SUKOVÁ M. (2004): Fungi on Juncus trifidus in the Czech Republic. I.   [Ascomycetes, anamorphic fungi, Hysteronaevia minutissima, Hysteropezizelladiminuens, Mycosphaerella perexigua var. minima, Naeviella paradoxa, Septoria, taxonomy, ecology]  Czech Mycology 56(1-2): 63-84   (published: 12th August, 2004)
  abstract   Fungi on Juncus trifidus were collected and studied during they ears 1998-2003, most intensively in 2002. Almost all known localities of this relict plant in the Czech Republic were visited. In this first contribution, 14 species of ascomycetes and anamorphic fungi are mentioned. Populations of Juncus trifidus in the Sudetes and Hercynian mountains are small in comparison with populations in the Alps and Carpathians. However, three species of arcto-alpine fungi (Hysteronaevia minutissima, Hysteropezizella diminuens, Naeviella paradoxa) and Lachnum roseum have been found there as new records for the Czech Republic. The richest localities of fungi on Juncus trifidus are Mt. Sněžka (Krkonoše Mts., Sudetes) and Jezerní stěna rock wall in the cirque of Černé jezero lake (Šumava Mts., Hercynicum).

  abstract   Three new species of Pyrenomycetes are described: Gnomonia alni-viridis, Mycosphaerella incomperta and Pleospora alnicola. These were collected on Alnus viridis, A. glutinosa, and A. incana in the vicinity of Kaplice, South Bohemia.

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.

ADAMČÍKOVÁ K., ONDRUŠKOVÁ E., PAŽITNÝ J., JÁNOŠÍKOVÁ Z. (2021): Divergence in culture morphology between two related species, Dothistroma septosporum and D. pini.   [Dothistroma needle blight, Pinus host, culture pigmentation.]  Czech Mycology 73(1): 109-119   (published: 24th May, 2021)   Electronic supplement
  abstract   Dothistroma needle blight (DNB) is one of the most important pine needle diseases worldwide. The disease is caused by two fungal species, Dothistroma septosporum and D. pini, which are similar not only in terms of their ecology, causing similar symptoms in hosts of the genus Pinus, but also in terms of their morphological characteristics. The morphologies of 353 cultured Dothistroma isolates from 11 different pine species in Slovakia and their relation to Dothistroma species and/or fungus origin (host) were studied and evaluated by means of the Chi-square test. The cultures were classified into eight categories according to pigmentation. Dothistroma pini isolates were assigned to 4 of the 8 categories, and D. septosporum isolates were assigned to all 8 categories with varying frequencies. The Chi-square test revealed that the culture morphology categories of D. pini and D. septosporum differed significantly. Interactions between the evaluated factors (culture morphology, Dothistroma and host species) were analysed and showed significant differences.

JAMALI S. (2020): First report of Paraconiothyrium fuckelii (Didymosphaeriaceae, Pleosporales), causing stem canker of Rosa hybrida, from Iran.   [Dothideomycetes, fungal disease, internal transcribed spacers, Iran mycobiota, pathogenicity.]  Czech Mycology 72(1): 71-82   (published: 29th May, 2020)
  abstract   In spring 2016, stem canker symptoms were observed on most Rosa hybrida plants in greenhouses of Kermanshah Province in Western Iran. Initial symptoms of the disease were brown necrotic lesions, mostly 8–10 mm long, on stems. The lesions eventually depressed and expanded to a long ellipse, resulting in yellowing and wilting of the foliage. Fungal colonies resembling those of Paraconiothyrium species were obtained from diseased tissues. Based on morphological and DNA sequence analysis of the internal transcribed spacers ITS1 and ITS2 and the 5.8S gene the fungal isolates were identified as Paraconiothyrium fuckelii. This is the first report of stem canker disease caused by this species in Iran. Pathogenicity tests were carried out on potted Rosa hybrida plants and detached branches under controlled conditions. Pathogenicity tests demonstrated that the fungus is able to infect and cause canker symptoms on inoculated branches of healthy plants after four weeks. The pathogen was re-isolated from all inoculated plants after observation of the symptoms, thus meeting Koch’s postulates.

MOUBASHER A.H., ABDEL-SATER M.A., SOLIMAN Z.S.M. (2018): Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt.   [fungal diversity, alkalinity, Wadi El-Natrun, lakes, Ibrahimia Canal, River Nile, molecular characterisation, ITS]  Czech Mycology 70(1): 1-32   (published: 26th January, 2018)
  abstract   The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi ElNatrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).

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.

GANNIBAL P.B., KAZARTSEV I.A. (2013): Development of a PCR assay for amplification of mating-type loci of Alternaria spp. and related fungi.   [population genetics, recombination, Ulocladium]  Czech Mycology 65(1): 69-78   (published: 10th June, 2013)
  abstract   A large number of ascomycete anamorphs including Alternaria spp. are considered asexual, but carry structurally conserved genes in a mating-type locus (MAT1) with two alternate idiomorphs, MAT1-1 and MAT1-2. Since the locus has lost its main function in many species, different directions of natural selection acting on the idiomorphs can be observed. Thus identification of mating types can be used in population biology studies. Also analysis of MAT1 locus sequences is needed for evolution and phylogeny reconstruction. Eighteen primers from previous works and this study were assessed for their ability to amplify MAT1 in 25 Alternaria and 7 Ulocladium, Embellisia and Alternariaster species. The most suitable primer pairs for 6 sections of Alternaria and several Ulocladium species were revealed.

JOHNOVÁ M. (2009): Diversity and ecology of selected lignicolous Ascomycetes in the Bohemian Switzerland National Park (Czech Republic).   [ascomycetes, lignicolous pyrenomycetes, biodiversity, ecology, endangered species]  Czech Mycology 61(1): 81-97   (published: 29th September, 2009)
  abstract   Lignicolous pyrenomycetes, their anamorphs and asexually reproducing Ascomycetes were investigated on deciduous and coniferous wood at 10 localities of the Bohemian Switzerland National Park (České Švýcarsko in Czech) during 2003–2005. A total number of 109 species was recorded, 11 species were found both as teleomorph and anamorph. Individual localities were evaluated from the viewpoint of Ascomycetes diversity. Ecological demands, relationship with the type of substratum, and microhabitat preferences were noted and several ecological groups are suggested. Rare and endangered species and factors affecting Ascomycetes diversity are discussed. Several species new to the Czech Republic were recorded, viz. Apiorhynchostoma altipetum, Camarops pugillus, Crassochaeta fusispora, Lophiotrema boreale, and Togniniella acerosa.

Colloquium „Fungi as Model Organisms in Research and Biotechnology - III“ Olomouc, Czech Republic, 2 September 2005.  Czech Mycology 57(3-4): 307-323   (published: 10th February, 2006)
  abstract   The colloquium was a continuation of the previous scientific meetings that took place in Olomouc in 1999 and 2002 (Czech Mycology 52: 139-178, 2000 and 55: 103-149, 2003). It was organised by the 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 aim of the colloquium was to provide a platform for a broad discussion on experimental mycology in all branches of basic and applied research. Besides two plenary lectures, 8 short communications and 8 posters were presented. In total 32 researchers from the Czech and Slovak Republics took part in the colloquium and discussed various topics important for the further development of experimental mycology. Abstracts of the contributions are given here.

SUKOVÁ M., CHLEBICKI A. (2004): Fungi on Juncus trifidus in the Czech Republic (II) with taxonomical notes to some species.   [Ascochyta, dark septate endophyte (DSE), Pseudoseptoria, Pycnothyrium, Septoria, Stagonospora, Unguicularia]  Czech Mycology 56(3-4): 203-221   (published: 22nd December, 2004)
  abstract   In this second contribution, other eight species of ascomycetes and anamorphic fungi on Juncus trifidus collected in the Czech Republic are described (Ascochyta junci, Lachnum diminutum, Phaeosphaeria vagans, Phialocephalasp., Pseudoseptoria sp., Pycnothyrium junci, Stagonosporajunciseda, Unguicularia sp.). Additional localities of Arthrinium cuspidatum and Niptera eriophori described in the first contribution are given. A fungus previously published as Septoria sp. was identified as Septoria chanousiana. Additional material of some fungi (Ascochyta junci, Septoria chanousiana, S. minuta, Unguicularia millepunctata) from other substrata and countries was studied with the aim to compare it with material from Juncus trifidus from the Czech Republic. Numbers of fungi on Juncus trifidus at studied localities are discussed.

BABU S., NANDAKUMAR R., SRIRAM S., RAGUCHANDER T., BALASUBRAMANIAN P., SAMIYAPPAN R. (2003): Phytotoxin production and rice sheath blight development by Rhizoctonia solani mutants derived from gamma irradiation.   [gamma rays, mutants, phytotoxin, Rhizoctonia solani, rice, sheath blight]  Czech Mycology 55(3-4): 261-271   (published: 22nd December, 2003)
  abstract   To evaluate the role of the RS-toxin, a phytotoxin produced by the fungus Rhizoctonia solani that causes sheath blight disease of rice, varying doses of gamma irradiation were used to generate mutants of the fungus. All the mutants showed reduced mycelial growth compared to the wild isolate RS7 in liquid culture. The mutants exhibited significant differences in virulence on detached leaf sheath and intact rice plants, the toxin produced and sclerotial formation in culture media and infected leafsheaths. The amount of toxin produced was positively correlated with disease development. SDS-PAGE analysis of mycelial proteins showed that the mutants and wild isolate produced many proteins of different molecular weights at different stages of mycelial growth. In the mutants resulting from higherdoses of gamma rays, the amount of toxin produced and their ability to induce disease symptoms were also greatly reduced.

SUKOVÁ M., SCHEUER C., BURYOVÁ B. (2003): New records and ecology of Naeviopsis carneola in Central Europe with notes on other fungi growing on Juncus filiformis.   [fungi on Juncus filiformis, Naeviopsis carneola, ecology, distribution, ta­xonomy, Central Europe, Czech Republic]  Czech Mycology 55(3-4): 223-239   (published: 22nd December, 2003)
  abstract   Naeviopsis carneola (Ascomycetes, Helotiales, Dermateaceae), earlier known only from three localities in Sweden and Poland, is reported from further localities in the Czech Republic, Poland, Germany and Austria. The ecology of the species in Central Europe is evaluated (habitat, altitude, period of fructification, occurrence on various parts of Juncus filiformis shoots and presence of associated juncicolous fungi). Known localities are mapped. A description based on recent collections, a drawing and for the first time also microphotographs (TLM) are provided.

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., ABDELZAHER H.M.A. (1999): Isolation of fungi from tomato rhizosphere and evaluation of the effect of some fungicides and biological agents on the production of cellulase enzymes by Nectria haematococca and Pythium ultimum var. ultimum.   [Biologicalcontrol, root-rot, fungicides Nectria haematococca, Pythium ultimum var. ultimum]  Czech Mycology 51(2-3): 157-170   (published: 25th May, 1999)
  abstract   Forty-five species and two species varieties belonging to twenty-six genera of fungi were isolated from 30 soil samples from the rhizosphere of tomato plants. The fungi most frequently isolated were Aspergillus flavus, A.fumigatus, A. niger, A. terreus, Gibberella fujikuroi, Nectria haematococca and Rhizopus stolonifer. Ridomil and Vitavax-captan (10, 50 and 100ppm) had no significant effects on the activity of Cl and Cₓ enzymes of Nectria haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but slightly decreased at 100ppm. Vitavax-captan (10, 50 and 100ppm) significantly decreased Cl enzyme activities of N. haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but at 100 ppm it showed a slightly inhibitory effect. Ridomil caused a slight increase in the activity of Cₓ and Cl enzymes by Pythium ultimum var. ultimum at low and moderate doses but the highest dose of Ridomil caused a slight reduction. Vitavax-captan slightly increased the activity of Cₓ and Cl enzymes in P. ultimum var. ultimum. Normal and sterilised filtrates of Myrothecium verrucaria, Penicillium oxalicum and Trichoderma harzianum induced a small decrease in Cl enzyme activity of Nectria haematococca. The sterilised filtrates of the three fungi tested caused greater inhibition compared to the normal filtrate. The production of Cₓ enzyme was slightly increased with normal and sterilised filtrates of Penicillium oxalicum and Trichoderma harzianum, but was significantly increased by both types of filtrates of Myrothecium verrucaria. The two types of filtrate of all fungi tested did not significantly affect the activity of Cl and Cₓ enzymes by lithium ultimum var. ultimum. Production of extracellular protein by Nectria haematococca was not significantly affected by any dose of the tested fungi cides. It was slightly increased by the two types of filtrate of the three tested fungi but significantly increased by the normal filtrate of Myrothecium verrucaria. The normal filtrate of all the fungi tested enhanced extracellular protein production to a greater extent than the sterilised filtrate. Extracellular proteins of Pythium ultimum var. ultimum were slightly increased by all doses of Vitavax-captan and low doses only of Ridomil, also two types of filtrate of all tested fungi caused a slightly increasing effect.

  abstract   The teleomorph-anamorph connections of Chaetosphaeria are discussed. On the basis of there vision of the type and other herbarium material, Zignoëlla crustacea, Lasiosphaeria britzelmayri subsp. fennica, Sphaeria decastyla and Melanomma macrosporum proved to be members of Chaetosphaeria. The new combinations Chaetosphaeria crustacea, Chaet. fennica and Chaet. decastyla, are proposed, Melanomma macrosporum is included in the synonymy of the latter. Chaetosphaeria crustacea has an anamorph intermediate between Chloridium and Cylindrotrichum, Chaetosphaeriafennica has a Chloridium-like anamorph, and Chaetosphaeria decastyla has Cacumisporium capitulatum as its anamorph. Two new species, Chaetosphaeria tulasneorum associated with the anamorph Cylindrotrichum oligospermum and Chaetosphaeria acutata associated with a Cylindrotrichum anamorph, are described. The teleomorph-anamorph connections of all accepted Chaetosphaeria species, except for Chaet. fennica, were confirmed by culture studies. Chaetosphaeria abietis and Chaet. fusi for mis are also considered, and the connection with the Chloridium cylindrosporum anamorph of the latter is confirmed by culture studies for the first time. The genus Cylindrotrichum and its relationship to Chloridium and other related genera is discussed. A key to the species of Chaetosphaeria with Cylindrotrichum and Cacumisporium anamorphs is provided.

  abstract   Revision of the type and other herbarium material of seven species previously placed in Chaetosphaeria Tul. et C. Tul. revealed that they need to be transferred to modern genera. Two new species, Calonectria rajasthanensis sp. nov. and Eriosphaeria subtomentosa sp. nov. are described and a new combination, Pseudotrichia xanthotricha (Berk, et Broome) comb. nov. is proposed. Four synonymous names are mentioned under other species names: Chaetosphaeria patelliformis Rick is identified with Byssosphaeria rhodomphala (Berk.) Cooke and Chaetosphaeria africana Saccas, Chaetosphaeria coffeae Saccas and Chaetosphaeria rehmiana (P. Henn.) Kirschst. are identified with Melanochaeta hemipsila (Berk, et Broome) E. Mull., Harr et Sulmont.

  abstract   Ascochyta avenae, Ascochyta tritici and Didymella sp. were identified on oats, wheat and barley leaves collected in 10 localities near Tachov (West-Bohemian region) in the spring of 1984. In our material yellow-and-brown lesions on oats were marginated dark red and contained irregularly dispersed pycnidia of Ascochyta avenae (Petr.) Sprague et Johns, [syn. Pseudodiplodia avenae (Petr.) Petr.]. Pycnidia were sized in average 139.5 x 134.25 µm, pycnospores 24.5 x 6.2 µm, having 1–2 septa. Infected spots of wheat and barley leaves were spindle-shaped, dark brown marginated. Ascochyta tritici Hori et Enjoji identified in wheat had pycnidia 138.5 x 130 µm in average, pycnospores 15.5 x 4.6 µm, normally having one central septum, two or even three septa were rare. In barley perithecia of fungus Didymella sp. were found 128 x 147 µm in average, with asci 55 x 11.5 µm and ascospores 15.5 x 6.2 µm, with one central septum. The above-mentioned fungi were cultivated on maltose-dextrose agar at 20–25°C, for 14 days under UV-light (365 nm).

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

  abstract   The production of uredia and telia in Uromyces pisi is shown to depend on the pH of the host tissue. Uredia and telia develop in tissues with pH above and below 6.3–6.5 respectively, confirming previous findings in cereal rusts and extending them to dicotyledons.

JECHOVÁ V. (1965): Some fungal parasits of Digitalis lanata Ehrh.  Česká Mykologie 19(1): 57-63   (published: 1965)
  abstract   The fungi causing diseases of cultivated Digitalis lanata in 1962–1963 include Colletotrichum fuscum, Fusarium oxysporum, and Botrytis cinerea. Their morphology, biology, and symptoms are described. These pathogens spread mainly through seeds and plant debris and further by rain, wind, insects, or cultivation activities.
