PARVEEN S., WANI A.H., BHAT M.Y., PALA S.A. (2018): Comparative study of the antimycotic activity of aqueous and ethanolic extracts of Berberis lyceum and Rumex obtusifolius against selected rot fungi. [plant extracts, phytochemicals, antimycotic effectiveness, minimum inhibitory concentration, inhibition zone] Czech Mycology 70(1): 47-56 (published: 16th March, 2018)
abstract
Two medicinal plants, Berberis lyceum and Rumex obtusifolius, were screened for the presence of various phytochemicals and for their antifungal activity. The phytochemical tests carried out in the present study demonstrated the presence of phenols, alkaloids, tannins, flavonoids, quinones and terpenoids in the plant extracts. Therefore, ethanolic and aqueous extracts of these medicinal plants were evaluated for their antifungal activity against Penicillium chrysogenum, Aspergillus niger, Cladosporium herbarum and Trichothecium roseum, using the agar well diffusion method. All the plant extracts at different concentrations showed significant antifungal activity against the tested fungi. Of the two plant extracts, B. lyceum showed stronger antifungal activity than R. obtusifolius. Ethanolic extracts of both plants showed stronger mycelial growth inhibition than aqueous extracts. The ethanolic extracts of B. lyceum showed the strongest antifungal activity against Penicillium chrysogenum (inhibition zone diameter of 41 mm) followed by the ethanolic extracts of R. obtusifolius against P. chrysogenum (inhibition zone diameter 39 mm). Hence, it is concluded that these medicinal plants have a broad-spectrum antifungal activity and are a potential alternative to reduce various fungal pathogens.

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.
ONDRÁČKOVÁ E., ONDŘEJ M., PROKINOVÁ E., NESRSTA M. (2013): Mycoparasitic fungi reducing the incidence and virulence of Bipolaris sorokiniana. [mycoparasitic activity, mycoparasitic fungi, Clonostachys, Trichoderma, Bipolaris sorokiniana] Czech Mycology 65(1): 103-112 (published: 10th June, 2013)
abstract
The mycoparasitic efficiency of 28 strains/isolates of Clonostachys rosea f. rosea and Clonostachys rosea f. catenulata against the pathogenic fungus Bipolaris sorokiniana was determined in dual cultures on Czapek-Dox nutrient agar. Strains with low and medium efficiency were antagonistically inhibited by B. sorokiniana, and inhibitory zones were formed between the colonies of both fungi. The mycelium of Clonostachys strains with high efficiency overgrew and degraded B. sorokiniana colonies without formation of an inhibitory zone. In dual cultures, Trichoderma sp. and the most effective Clonostachys strains degraded B. sorokiniana colonies within 3 to 5 and 12 to 15 days, respectively.When rye seeds were treated with a mixture of C. rosea f. rosea, Trichoderma sp. and B. sorokiniana, development of B. sorokiniana on both seeds and seedlings was reduced when compared with a B. sorokiniana treatment. The treatment of rye seeds with Clonostachys and Trichoderma had a positive effect on seed germination and seedling length.
KUNCA V. (2011): Ecology and incidence of Polyporus umbellatus in Slovakia. [Polyporus umbellatus, ecology, pH values, incidence, Slovakia] Czech Mycology 63(1): 39-53 (published: 10th August, 2011)
abstract
Research of the incidence of Polyporus umbellatus (Pers.) Fr. was carried out in 37 plots covering a diverse range of conditions in Slovakia. Based on measurements of soil pH values, this fungal species prefers acid soils. The highest number of sporocarps per plot during the three years of monitoring was detected every July. The majority of localities with incidence of P. umbellatus were located in hilly terrain, fewer in lowlands and very occasionally in uplands. Sclerotium and sporocarps predominantly occur at a specific distance from colonised beech, hornbeam and oak trees, with fewer individuals found in the vicinity of the host trees. Data from the research confirm that this species is well represented in Slovakia, nevertheless published data on its incidence and habitat are still rare.
KAUTMANOVÁ I., KAUTMAN V. (2006): Cordyceps rouxii (Ascomycetes, Clavicipitales) in Slovakia and Czech Republic, with notes to distribution, ecology and taxonomy. [Cordyceps capitata, Cordyceps longisegmentis, epitype] Czech Mycology 58(3-4): 173-188 (published: 29th December, 2006)
abstract
Cordyceps rouxii, a new species for Slovakia and Czech Republic was recorded in 2004. Revision of herbarium collections revealed that this species has been often misidentified as C. capitata and is more common than was expected. After revision of the type material the authors propose an epitype based on a Slovak collection.
HOSHINO T., PROŃCZUK M., KIRIAKI M., YUMOTO I. (2004): Effect of temperature on the production of sclerotia by the psychrotrophic fungus Typhula incarnata in Poland. [sclerotium size, snow mold fungi, Typhula incarnata] Czech Mycology 56(1-2): 113-120 (published: 12th August, 2004)
abstract
Isolates of the snow mold fungus Typhula incarnata from Radzików, Blonie, near Warsaw in Poland formed many small-sized sclerotia (< 1 mm) at 0°C. This phenomenon was not observed in other isolates from different locations that have regions with annual snow cover. The formation of small-sized sclerotia by Polish isolates decreased with rising temperature, but the formation of large-sized sclerotia increased.
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.
ŠIMONOVIČOVÁ A. (2001): Supplement to the Checklist of non-vascular and vascular plants of Slovakia. The species of microscopic fungi of the order Eurotiales. [new records of microscopic fungi (Eurotiales), Checklist of non-vascular and vascular plants of Slovakia] Czech Mycology 53(2): 173-188 (published: 20th February, 2002)
abstract
Submited are 50 species of microscopic fungi of the order Eurotiales, which are not listed in the Checklist of non-vascular and vascular plants of Slovakia, part Fungi (Lizoň and Bacigálová 1998). The first group is presented by those microscopic fungi which were isolated only once so far. So we consider them to be scarce or rare. From among 30 species of microscopic fungi more than a halfbelongs to the genus Penicillium (16 species ) or genus Aspergillus (6 species ). The genera Eupenicillium, Eurotium and Paecilomyces have two new species, Emericella and Merimbla only one species. The second group is presented by more frequently isolated species of microscopic fungi. From among 20 species the genus Penicillium dominates with 8 species, followed by the genus Aspergillus with 4 species. Other genera(Byssochlamys, Dichotomomyces, Eupenicillium, Eurotium, Fennellia, Paecilomyces and Talarornyces) are presented with one or two species. From the total number of 50 species of microscopic fungi the prevailing part was isolated from different soils (73.3-75.0 %), from different food stuffs (3.3-30.0 %) and from other sources (23.3-45.0 %), including drinking water, dwellings and different materials in depositories and archives.
HUŇKOVÁ Z., KUBÁTOVÁ A., WEIGNEROVÁ L., KŘEN V. (1999): Induction of extracellular glycosidases in filamentous fungi and their potential use in chemotaxonomy. [glycosidases, induction, Aspergillus, Penicillium, Fusarium] Czech Mycology 51(1): 71-87 (published: 29th January, 1999)
abstract
Data on the occurrence and inducibility of extracellular β-N-acetylhexosaminidase, α-galactosidase, α- and β-mannosidase and α-L-fucosidase, including inductors, are given for selected Aspergillus, Penicillium and Fusarium strains. These data represent additional information on the strains in the Culture Collection of Fungi, Department of Botany, Charles University, Prague, and in the Culture Collection of the Institute of Microbiology, Prague, Czech Republic, thus extending their usability in biochemistry and biotechnology. With respect to these biochemical data a taxonomic evaluation of the examined strains is presented. Several strains were re identified after biochemical and morphological comparisons with the type strains. The strains of A. niveus CCF 544, A. terreus CCF 76, CCF 869, and CCIM USA were re-identified as A. flavipes, the strain A. oryzae CCF 1301 as A. wentii.

abstract
The fungi Gliocladium roseum, Trichothecium roseum, Trichoderma harzianum, Trichoderma viride, Penicillium cyclopium and Acremoniella atra were isolated from onion bulbs infected with parasitic fungi Botrytis allii, Botrytis cinerea, Botrytis squamosa, Sclerotium cepivorum and Fusarium oxysporum. Some of them exhibited antagonistic effects on the pathogens causing storage rots under in vitro and in vivo conditions.
BRILLOVÁ D., ŠUŤÁKOVÁ G. (1984): Viruslike particles in hyphae of parasitic fungus Cercospora beticola Sacc. Česká Mykologie 38(4): 193-196 (published: 15th November, 1984)
abstract
In the present paper we summarize the results of electron microscope investigation of the hyphae of three singlespore isolates of Cercospora beticola and a sterile mutant. In ultrathin sections of hyphal cells we have found two types of viruslike particles of spherical shape, 30—35 and 50—55 nm in diameter. They were dispersed in the cytoplasm and occasionally in the vacuoles as well. Viruslike particles of both types occurred together in the hyphal cells of the strain Mss2, whereas the hyphal cells of strain PR13 contained viruslike particles only one dimension, i.e. there were cells containing 30—35 nm and others 50—55 nm viruslike particles. In the infected cells we observed changes of mitochondria, the occurrence of lamellar structures, changes of cell walls leading to the disruption and liberation of viruslike particles from the cells. The sporulation of infected strains was considerably lower than in healthy one.

abstract
The effect of UV radiation on the germination of conidia and the growth of Erysiphe graminis f. sp. hordei on barley was studied. UV radiation affected fungal vitality and reproduction capacity depending on the development stage. The most sensitive phase to radiation was identified, showing significant physiological impact during the asexual cycle of this common parasite.
