MINTER D.W. (1981): Microfungi on needles, twigs and cones of pines in Czechoslovakia. Česká Mykologie 35(2): 90-101 (published: 1981)
abstract
One hundred and forty-seven species of microfungi are listed from rotting needles, twigs and cones of pines in Czechoslovakia (mostly from Bohemia). Thirty-seven of these are reported as new from this region. The Czechoslovak pine mycoflora is compared briefly with those of other countries and is found more varied than any previously recorded.
HOLUBOVÁ-JECHOVÁ V. (1970): The internal rots of Brazil nuts. Česká Mykologie 24(4): 207-214 (published: 29th October, 1970)
abstract
The author isolated and identified fungi causing the internal decay of Brazil nuts (Bertholletia excelsa). The fungi included Absidia blakesleeana, A. cylindrospora, Circinella muscae, Cunninghamella elegans, Rhizopus arrhizus, R. nigricans, R. oryzae, Aspergillus flavus, A. tamarii, A. wentii, Fusarium javanicum, Penicillium frequentans, P. cf. phialosporum, P. wortmanni, Trichoderma viride and Verticillium sp. These fungi were found in nuts with normal appearance but internal spoilage, and were responsible for rancidity and bitterness of the kernels.
KRUPODOROVA T., BARSHTEYN V., KIZITSKA T., RATUSHNYAK V., BLUME Y. (2023): Antagonistic activity of selected macromycetes against two harmful micromycetes. [ascomycetes, Aspergillus niger, basidiomycetes, dual-culture, Penicillium polonicum.] Czech Mycology 75(1): 85-100 (published: 23rd June, 2023)
abstract
Competition between 31 macromycete species and two harmful micromycetes Aspergillus niger and Penicillium polonicum was evaluated using dual-culture plate assay. All investigated fungi, except for Inonotus obliquus and Lepista luscina, possessed different levels of antagonistic activity against the tested micromycetes. Hypsizygus marmoreus and Lyophyllum shimeji were inactive against A. niger. Morchella esculenta and Oxyporus obducens were passive in the case of co-growth with P. polonicum. The study of fungal interactions showed variability in types of reactions and level of their visualisation. Co-cultivation of the studied species resulted in the following reactions: deadlock after mycelial contact and at a distance, partial or complete replacement after initial deadlock on contact. In general, the studied macromycetes showed moderate activity against the two micromycetes, as 11 species showed active and 7 species moderate antagonism. Results revealed higher antagonistic activity of macromycetes against P. polonicum than in A. niger co-cultures. Wood-decaying species Ganoderma lucidum and Trametes versicolor were the most active fungi against the two tested micromycetes with a maximal antagonism index. These findings provide valuable insights which can be further explored by means of in vivo assays to find a suitable agent for the biocontrol of diseases or spoilage caused by A. niger and P. polonicum.
NOVOTNÝ D. (2022): Contribution to the endophytic mycobiota of aerial parts of oaks. [endophytes, Czech Republic, Quercus robur, Quercus petraea, acorns, seeds, twigs.] Czech Mycology 74(2): 111-121 (published: 1st July, 2022)
abstract
The endophytic mycobiota inhabiting branches of Quercus petraea from two localities in the Křivoklát area, and branches, twigs and acorns of Quercus robur from one locality near the town of Semily were studied (all sites in the Czech Republic). Seventeen fungal taxa were isolated from branches of Q. petraea. Dominant fungi were found to be Colpoma quercinum and Phoma sp. as well as sterile dark mycelium and a black yeast-like fungus close to Sarcinomyces crustaceus. Eighteen fungal taxa were found in samples of aerial parts in Quercus robur. The most frequently isolated taxa were Pezicula cinnamomea, Colpoma quercinum, Alternaria alternata agg. and Acremonium sp.
DEEPTHI A.S., RAY J.G. (2021): Ecological relevance of the endophytic fungal diversity in velamen roots of tropical epiphytic orchids. [epiphytes, Orchidaceae, root-associated endophytes, Trichoderma, Endomelanconiopsis, Lasiodiplodia.] Czech Mycology 73(1): 91-108 (published: 17th May, 2021)
abstract
The velamen roots in epiphytic orchids are rather complex, and their environmental role remains poorly understood. Fungal associates are known in the velamen roots of tropical orchids, but the magnitude of their diversity in particular species remains unknown. The primary aim of this work was to explore endophytic fungal species associated with the velamen roots of three tropical epiphytic orchids. Velamen roots were collected from 30 plants of Rhynchostylis retusa and 25 plants each of Epidendrum radicans and Oncidium sphacelatum. Endophytic fungi were isolated from 2160 segments. Twenty species of velamen-root-associated fungal endophytes were separated with a culture technique. The isolated strains were grouped into morphotypes, subsequently identified morphologically and by means of ITS DNA barcoding. Ascomycota were the dominant group with 18 species. Trichoderma cf. asperellum, Endomelanconiopsis endophytica, Trichoderma cf. atroviride and Lasiodiplodia theobromae were the most frequent taxa isolated. A majority of the identified fungi were common to more than one orchid. Colonisation rate, isolation rate, Shannon-Wiener diversity index, species richness and species evenness of the endophytic fungi from different orchids were studied and were tested for significance with the Kruskal-Wallis H test. The colonisation rate and isolation rate of fungal associates in the velamen roots were found to be distinctly the lowest in Rhynchostylis retusa.
ABDEL-SATER M.A., MOUBASHER A.H., SOLIMAN Z.S.M. (2016): Diversity of filamentous and yeast fungi in soil of citrus and grapevine plantations in the Assiut region, Egypt. [Mycobiota, biodiversity, phenotypic and biochemical characterisation, ITS sequence, Coniochaeta canina, Aspergillus stella-maris] Czech Mycology 68(2): 183-214 (published: 20th December, 2016)
abstract
An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25 °C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species).Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9–100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1–83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3–100% on DRBC and 38.9–50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.
PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review. [biological control, postharvest diseases, microbial pesticides, rosaceous fruits] Czech Mycology 68(1): 41-66 (published: 1st February, 2016)
abstract
This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.
HASHEM M. (2004): Biological control of two phytopathogenic fungal species isolated from the rhizoplane of soybean (Glycine max). [biological control, soybean, Macrophominaphaseolina, Rhizoctonia solani] Czech Mycology 56(3-4): 223-238 (published: 22nd December, 2004)
abstract
Two hundred isolates representing 31 fungal species (20 genera) were recovered from soybean roots. Samples were collected from 12 localities at 3 different growth stages of the crop. The most dominant species were Aspergillus flavus, Fusarium oxysporum, Fusarium solani (Nectria haematococca), Macrophomina phaseolina and Rhizoctonia solani. Pathogenicity tests have proved the ability of Macrophomina phaseolina and Rhizoctonia solani to infect soybean roots and produce the symptoms of damping-off and root-rot diseases.The efficacy of three antagonists (Trichodermaharzianum, Epicoccum nigrum and Paecilomyceslilacinus) as well as two organic compounds (Strom and F-760) was evaluated as to their control of pathogenic fungi . Biocontrol fungi significantly suppressed Macrophominaphaseolina and Rhizoctonia solani in vitro and in vivo. Epicoccum nigrum and Paecilomyces lilacinus suppressed the growth of the pathogens by producing an inhibition zone while Trichoderma harzianum suppressed them by overgrowing. Strom and F-760 showed lower reduction effect of diseases in comparison with the antagonists.
Colloquium "Fungi as Model Organisms in Research and Biotechnology - II", Olomouc, Czech Republic, September 5th–6th, 2002. Czech Mycology 55(1-2): 103-149 (published: 23rd July, 2003)
abstract
The colloquium was a continuation of a previous scientific meeting that took place in Olomouc in 1999 (Czech Mycology 52: 139-178, 2000). It was organised by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: biochemistry, biotechnology and genetics of fungi; phytopathogenic fungi; fungi pathogenic to humans and animals; and mycology of food and mycotoxins. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides five plenary lectures, 20 short communications and 24 posters were presented. In total 42 researchers took part in the colloquium and discussed various topics important for the further direction of experimental mycology. Abstracts of the contributions are given here.
NOVÁKOVÁ A., PIŽL V. (2003): Mycoflora in the intestine of Eisenia andrei (Oligochaeta, Lumbricidae) and in vermiculture substrates. [cattle manure, saprotrophic and cellulolytic microfungi, earthworms] Czech Mycology 55(1-2): 83-102 (published: 23rd July, 2003)
abstract
Mycoflora of three commercial vermiculture systems based on cattle manure derived sub strates and Eisenia andrei earthworms was studied using several isolation methods. A total of 172 taxa of saprotrophic micromycetes were isolated (19 taxa of Zygomycetes, 9 taxa of Ascomycetes and 144 taxa of mitosporic fungi). Aspergillus fumigatus was the most frequent microfungal species in the intestine of Eisenia andrei. In vermicuture substrates, Aspergillus flavus and Aspergillus fumigatus were among species isolated very frequently by the soil dilution method, while Rhizopus stolonifer was estimated as frequent species using the soil washing isolation technique.
NOVOTNÝ D. (2003): A comparison of two methods for the study of microscopic fungi associated with oak roots. [Quercus robur, oakdecline, Czech Republic, mycobiota, ophiostomatoid fungi] Czech Mycology 55(1-2): 73-82 (published: 23rd July, 2003)
abstract
Roots of four trees with symptoms of oak decline and roots of one healthy tree of Quercus robur were examined for the presence of fungi by using two methods (moist chambe rmethod and strong surface sterilisation method). Forty-five species were isolated in this project. Significant differences in composition of mycobiota based on the used method were detected. Fusarium solani, F. proliferatum, Sphaerostilbella aureonitens, Cylindrocarpon destructans, Pénicillium simplicissimum, P. purpurogenumvar. rubrisclerotium, Trichodermaviride, Ophiostomapiceae s.l. and Pénicillium glandicola were the most frequent fungi isolated by the moist chamber method. Cryptosporiopsis radicicola, dark sterile mycelium sp. 1, Cylindrocarpon destructans, ChaetomiuM globosum, Cylindrocarpon didymum, Pénicillium simplicissimum and Trichoderma koningii were dominant species observed by the method of strong surface sterilisation.
NOVOTNÝ D. (2002): Contribution to the knowledge of the mycoflora in roots of oaks with and without tracheomycotic symptoms. [Quercus robur, Q. petraea, Q. rubra, oak decline, ophiostomatoid fungi, Penicillium, Czech Republic, Moravia] Czech Mycology 53(3): 211-222 (published: 10th January, 2002)
abstract
The mycoflora of roots of three species of oak (Quercus robur, Q. petraea, Q. rubra) from two localities near Moravské Budějovice (southwest Moravia, Czech Republic) with and without tracheomycotic symptoms was studied. Fifty-seven species of fungi were identified from the samples. The most frequently isolated were Fusarium solani, Penicillium gl and icola, P. glabrum, P. simplicissimum and Acremonium curvulum. In the roots of trees with tracheomycotic symptoms two species of ophiostomatoid fungi were recorded. Abiotic condiontions (insufieciency of precipitation and higher average temperature) are considered to be primary reasons of oak decline.
HÝSEK J., BROŽOVÁ J. (2001): The role of some saprophytic micromycetes and fungus Micromucor ramannianus var. ramannianus in forest soil. [humic horizon, soil fungi, saprophytic micromycetes, Micromucorramannianusvar. ramannianus, biological soil functions, respiration, ammonification, nitrification] Czech Mycology 53(2): 161-171 (published: 20th February, 2002)
abstract
Different saprophytic micromycetes were isolated from the humic horizon (H-A 02) of different types of forest soils (barren l and of reforested waste dumps, cambisol of spruce, birch, European mountain ash, and blue spruce forests) in several areas (at Most in the Krušné hory (Ore Mts.), Jizerské hory (Izera Mts.)). Besides the spectrum of common species of soil micromycetes (Penicillium spp., Humicola spp., Trichoderma spp., Paecilomyces spp., Scopulariopsis spp., Aureobasidium spp., Mucor spp., Absidia spp.), the fungus Micromucor ramannianus (Möller) Arx var. ramannianus (Mortierella ramanniana (Möller) Linneman, Mucor ramannianus Möller) was regularly isolated from all types of soils, except barren soils of was te dumps. The biological quality of forest soils in connection with other biological characteristics was evaluated in relation to the presence and quantity of this fungus in forest soils. Basic biological processes (basal and potential respiration, ammonification, nitrification) show an increased intensity in forest soils in which the proportion of Micromucorramannianus v. ramannianus was not present in the soil of the worst biological quality (lower values of biological soil parameters), e.g. in of was te dumps. It is a topic for discussion whe the r this fungus can also be an indicator of environmental pollution.
MOSTAFA M.E., ZOHRI A.A., KOTBY R.S. (2001): Lipid, sterol and ergosterol accumulation in isolates of dematiaceous Hyphomycetes. [Lipid, sterol, ergosterol, dematiaceous hyphomycetes] Czech Mycology 53(2): 149-159 (published: 20th February, 2002)
abstract
Mycelial dry weight, lipid and sterol contents of fungi tested varied with fungalgenus, species and even with isolate of one species. Their dry mass fluctuated between lll.6±l0.7-457.0±41.5 mg/50 ml medium. Lipids, sterols and ergosterol accumulated by the isolates tested ranged from 4.52±0.5-29.04±2.76%, 1.23±0.16-10.63±l.24% and 0.43±0.057-7.13±0.695% of their dry mass, respectively. Cochliobolus spicifer isolate No. 35 was the highest lipid-producer while Ulocladium atrum No. 90 proved to be superior in the production of sterols and ergosterol. TLC technique and chemical analysis of lipid classes produced by U. atrium No. 90 revealed that the lipid fractions are composed of free sterols, free fatty acids, sterol esters, glycolipids, phospholipids and squalene.
GHERBAWY Y.A.M.H., PRILLINGER H. (2000): Root mycoflora of pepper (Capsicum annuum) antagonistic to Verticillium dahliae. [Frequency of root fungi, Verticillium dahliae, Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, Trichoderma harzianum, pepper seed germination] Czech Mycology 52(3): 219-226 (published: 7th December, 2000)
abstract
Thirty-two species belonging to 19 genera of fungi were collected from 30 soil samples from the rhizosphere of pepper plants. The fungal colonies were characterised using classical morphological methods following identification keys. The most frequently isolated fungi were Chaetomiumglobosum, Fusarium oxysporum, Gliocladium roseum, Mucor racemosus, Myrothecium verrucaria, Penicillium aurantiogriseum, P. expansum and Trichoderma harzianum. The crude culture filtrate of Verticillium dahliae at 100% concentration caused sharp decrease in pepper seed germination. Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, and Trichoderma harzianum produced a metabolite that retarded radial growth of Verticillium dahliae.

Abstracts of the contributions are given here.
REINPRECHT L. (1998): Loss of antifungal activity of selected fungicides in treated wood due to natural ageing. Part 1: Activity against moulds. [2-thiocyanomethylthiobenzothiazole, organotin fungicides, beechwood, natural ageing, moulds] Czech Mycology 50(4): 249-258 (published: 12th July, 1998)
abstract
The activity of 2-thiocyanomethylthiobenzothiazole (TCMTB) and selected organotin com pounds (OTC = TBTO, TBTS, TBTCA and TBT-DEDTK) against moulds was evaluated by means of mycologicaltestsin which treated and subsequently naturally aged beechwood samples were exposed to the effect of a mixture of six moulds under laboratory conditions. Natural ageing of the treated samples took place under an angle of 45’, and during periods of 0, 2 or 4 months. TCMTB was characterized as the relatively most stable fungicide with antimould activity.
ABDEL-MALLEK A.Y., MAZEN M.B., ALLAM A.D., HASHEM M. (1997): Specific responses of some phytopathogenic fungi to fungicides. [fungicides, phytopathogenic species, Egypt] Czech Mycology 50(1): 35-44 (published: 29th September, 1997)
abstract
Laboratory experiments were carried out to examine the effect of four fungicides on spore germinating potentialities, radial growth and survival of viable propagules in soil of five phytopathogenic fungal species. The test organisms were achieved from infected roots of wheat plants cultivated in the Assiut area, Egypt. These were: Altemaria alternata, Cochliobolus sativus, Drechslera halodes, Fusarium moniliforme and F. oxysporum. The fungicides reduced germ tube production and radial growth of all fungi, and the reduction increased with increase in concentration. The maximal reduction was recorded at 50 μg/ml. At this concentration, Homai prevented spore germination of all test species. Neither F. moniliforme nor F. oxysporum can grow on agar medium supplemented with 50 μg/ml of either Benlate or Homai. The suppressive effect of fungicides on spore survival in soil cultures was also noticed but seemed to be lower than in agar application. In certain treatments, the numbers of viable propagules of tested fungi were not significantly affected in autoclaved nor non-autoclaved soil.
FASSATIOVÁ O. (1995): Micromycetes in archives and book depositories in the Czech Republic. [Micromycetes, archives, allergies, Czech Republic] Czech Mycology 48(1): 77-86 (published: 16th May, 1995)
abstract
Species representation of micromycetes and their frequency were studied in the period 1981-1988 in four archives in Prague and near Prague and in one depository in West Bohemia. Representants of genera Penicillium, Cladosporium, Alternaria, Aspergillus, Mucor and Rhizopus isolated by sediment plate method and from the surfaces of the archive depots were the most frequent in all observed spaces. The higher number of the most frequent species was always found in older and for the archive purposes less convenient buildings, while inside the new building the number of the most frequent species was very low. In suitable conditions only a limited number of species for which the given specific conditions are convenient, act as destructive. They are mostly Penicillium which form coherent growing covers on the backs of the books and cartons. Spores of these fungi released by their growth contaminate the atmosphere of these spaces and can cause allergies in sensitive persons.
NOVÁKOVÁ-ŘEPOVÁ A., CHALUPSKÝ J. (1993): Microscopic fungi isolated from Fridericia galba (Oligochaeta, Enchytraeidae). Česká Mykologie 46(3-4): 251-255 (published: 25th August, 1993)
abstract
Microscopic fungi were isolated from the enchytraeid Fridericia galba (Hoffmeister, 1843), and from surrounding soil. Isolation was done from aseptically squashed enchytraeid bodies and from enchytraeid excrements prepared by defaecation into sterile conditions. The cultivation media were soil extract agar, cherry decoction agar and beer wort agar. A total of 39 fungal species was found, 29 in the excrements and 19 in the soil. In most cases, fungi isolated from the soil differed from those isolated from the excrements. Feeding preference and seasonal variation were not demonstrated. Spores of fungi were viable after passage through the enchytraeid gut. The biochemical activity of the isolated fungi indicates preferential feeding on plant remains where the degradation of cellulose, pectin and xylose predominates.

abstract
On five localities in vallies Krížna, Koprová and Furkotská (High Tatra Mts.) we investigated the species structure of soil microscopic fungi and the similarity of mycocenosis. The arenic podzol and podzolic ranker soils were studied. The soils had low to very low acid reaction and very low content of organic matter. In the global number of isolated soil microscopic fungi species (48), the cosmopolitan genus Penicillium of the family Moniliaceae was dominantly represented. The species of the family Mucoraceae were suppressed as the result of the soil quality decreasing, which reflects the degradation of the quality of the whole environment in High Tatra Mts. The highest index of similarity – S = 0.6 – was proved between the localities in the neighboring vallies.
ŠIMONOVIČOVÁ A. (1992): Microfungal community structure in forest soil of North Slovakia. I. Similarity of mykocenosis (The Valley Tichá). Česká Mykologie 46(1-2): 99-105 (published: 1st April, 1993)
abstract
Microfungal community structure in four forest localities in the Valley Tichá in the High Tatra Mountains was studied. Podzolic and ranker soils are poor in organic matter, physically and chemically unfavourable. The pH values are lower – by 1.0 to 1.5 – than values in 1962, which means that the quality of the soils has degraded. These differences correspond with the quality of mycocenosis, which has also worsened. 41 species of soil micromycetes were isolated. The occurrence of the representatives of the genus Penicillium (fam. Moniliaceae) was the highest. The occurrence of the representatives of the family Mucoraceae was suppressed. The similarity of the neighbouring mycocenoses was higher than that of those more distant from each other.

abstract
The changes of fungal growth in laboratory experiments (estimation of mycelial biomass and colony diameter) were studied by cultivation of 10 species of soil fungi on media with different concentrations of the herbicides Basagran, Labuctril 25 and Oxytril CM. The subject fungi responded to increased concentrations of herbicide in different ways. Cladosporium herbarum (colony diameter) and Penicillium janthinellum (mycelial biomass) were the only investigations to show a similar response to all the herbicides. Penicillium janthinellum (mycelial biomass) was the only example of a significant stimulation of fungal growth. Changes in colony pigmentation and sporulation were also recorded.

abstract
In the course of the years 1988–1991 the author used to visit large-scale greenhouses at Paskov near Ostrava (NE Moravia, Czechoslovakia) and surveyed not only the abundant growth of particularly higher fungi there, but in 1989 he tried to summarize the weight of biomass of the most frequent species. The results of the observation of biomass, frequency, abundance and phenology are presented in the tables. Altogether 95 macrofungi taxons, 1 species of Hyphomycetes and 1 species of Myxomycetes were recorded and they are given in the systematic summary, potentially with comments.

RYPÁČEK V. (1986): Some interesting ways of wood infection by fungi. Česká Mykologie 40(4): 193-202 (published: 7th November, 1986)
abstract
Infections caused by wood-decay fungi proceed in various ways depending not only on the fungal species but also on the substrate's chemical and physical properties. Spores released from hymenia may reach hundreds of thousands per hour per square decimeter, attacking both living and dead wood. Successful colonization is influenced by microbial antagonists like Trichoderma viride or Bacillus asterosporus. Spores may lose viability within days if they fail to germinate. In trees, wounds allow entry, and anatomical structure affects spore migration.
BETINA V. (1986): Fungi in biotechnology-history, present times, perspectives. Česká Mykologie 40(2): 65-73 (published: 10th May, 1986)
abstract
A review of applications of fungi in biotechnology from the old ages to the present times is presented. Origins of vine and beer fermentation as well as leavened bread making are lost in the mist of antiquity and records of the production of Roquefort cheese go back about a thousand years. On the other hand, commercial production of yeast began in the last century and the production of single-cell proteins (SCP) was born in our century. Nowadays, fungi are further used in commercial production of enzymes, organic acids, vitamins, antibiotics and plant growth regulators, in biotransformations of steroids and antibiotics, in the ephedrin synthesis and in preparation of other pharmacologically useful substances. Great achievements were obtained by applying classical genetic methods. Possibilities of the use of protoplast fusion and recombination, gene amplification or recombinant DNA technology using restriction enzymes are discussed.

STANĚK M. (1984): Microorganisms in the hyphosphere of fungi. I. Introduction. Česká Mykologie 38(1): 1-10 (published: 10th February, 1984)
abstract
The surface and immediate surroundings of fungal hyphae affected by their activity is termed the „hyphosphere“. Differences between microorganisms colonizing the hyphosphere and those colonizing a substrate is termed „hyphosphere effect“. The more extensive area of fungal effect on substrate, on the surface and surroundings of fruit-bodies, i.e. the environment affected by the activity of fungi is termed „mycosphere“. The nomenclature proposed is in agreement with the classification of the phytosphere of higher plants. The brief literary survey presents data on incidence of microorganisms in hyphosphere and on their importance, taking into account the results obtained in the Czechoslovak research institutions.

abstract
In three forest sites of the Nature reserve “Voděradské bučiny” soil microfungi were studied in the period from September 1978 to July 1979. A total of 66 species was identified, 9 of which belonged to Mucoraceae and 57 to Moniliales. The most common species were Penicillium albidum Sopp emend. Fass. (all sites) and Trichoderma viride Pers. ex S. F. Gray (beech forest, beech forest with Dicranum), Absidia cylindrospora Hagem (beech forest), P. spinulosum Thom (beech forest with Dicranum, spruce forest), P. chrysogenum Samson, Hadlok et Stolk (beech forest, spruce forest). The greatest number of species was found in the spruce forest. The highest biomass values of mycelium and of spores were ascertained in stony soil of the beech forest with Dicranum scoparium.

abstract
Within the framework of the 1973 Czechoslovak expedition in the Makalu Mountain region in the Himalayas (East Nepal) a total of 43 soil samples were collected for mycologic examination. Fourteen genera with 37 species of soil fungi were isolated from the samples. Though the spectrum of the isolated microscopic fungi was not wide, it contained 2 genera (Acremonium and Tolypocladium) and 15 species described for the first time amongst the Himalayan mycoflora. Some of the species were collected in the area for the second time. Among the keratinophilic microscopic fungi, Chrysosporium lucknowense was isolated. The investigation and the collection of soil samples took place at the altitudes of 1000–4900 m in the sites where the presence of terrestrial mammals was established, or direct from lair openings. The aim was to detect potentially pathogenic or keratinophilic microscopic fungi. Various species of microscopic fungi were isolated for the first time from the extreme climatic conditions of the high mountains characterized by an increased occurrence of UV radiation, great temperature fluctuations, strong air flow, a decrease in the air pressure and oxygen content and extreme abiotic and biotic factors influencing the specific existence of the organisms.

abstract
During investigations of colonization of healthy emerged sugar beet roots by microorganisms, the fungus Pythium oligandrum Drechsler was found on the root surface of sugar beet seedlings which already had true leaves, in Semčice (Central Bohemia) in 1972. Infection tests proved a low degree of pathogenicity of this fungus towards sugar beet seedlings. In laboratory conditions, Pythium oligandrum showed strong parasitism against Pythium ultimum Trow and Pythium debaryanum (Hesse) De By., which are significant root rot pathogens of sugar beet. In dual cultures with these fungi, P. oligandrum usually dominated the substrate within 24 hours after inoculation and completely destroyed or strongly suppressed the other fungus growing with it on agar medium. Because Pythium oligandrum exhibits only very weak pathogenicity towards sugar beet but is a strong parasite of P. ultimum and P. debaryanum, which it shares the rhizosphere with, its potential use for biological control of sugar beet root rot is discussed, using biopreparations applied to sugar beet seed.

abstract
Extensive growths of Armillaria mellea rhizomorphs were observed in timber supports in a coal mine shaft in Kladno, Bohemia. Laboratory and in situ experiments on wood protection were conducted. The fungicides Lastanox Q and Universal proved effective. Imperfect fungi such as Trichoderma viride, Aspergillus niger, and Cladosporium avellaneum also showed inhibitory effects on rhizomorph development.

abstract
A total of 122 species of soil micromycetes were identified in 1963 in Ždánický les and the Pouzdřany steppe (South Moravia), including 25 species of Mucorales and 57 of Moniliales. Species diversity was proportional to soil temperature but not to humidity. Steppe was dominated by Aspergillus and Fusarium; forests by Chrysosporium pannorum.
PŘÍHODA A. (1965): Essai expérimental d’une protection biologique du bois dans les mines. Česká Mykologie 19(3): 175-179 (published: 1965)
abstract
Experimental infections were conducted in the Kladno coal mines using several strains of Trichoderma viride to control wood-decay fungi. Only one strain, isolated from a poplar branch parasitizing Chondroplea populea and Cytospora chrysosperma, was effective against Serpula lacrymans, Heterobasidion annosus, and Fomitopsis pinicola. This early biological wood protection attempt, though discontinued, offers potential for renewed research.
