LYTVYNENKO YU.I., HAYOVA V.P., AKULOV O.YU., DZHAGAN V.V., ROMANOVA D.A. (2022): An update on the occurrence of the Sporormiaceae (Pleosporales) in Ukraine.   [coprophilous fungi, distribution, morphology, Preussia, Sporormia, Sporormiella.]  Czech Mycology 74(2): 195-226   (published: 12th December, 2022)
  abstract   The article provides an update on the dung-inhabiting members of the Sporormiaceae in Ukraine. Overall, 26 species of Sporormia and the Preussia/Sporormiella species complex have been recorded in the country to date. Based on examination of specimens collected in 2007–2020, we report one species of Sporormia (S. fimetaria), two of Preussia s. str. (P. fleischhakii, P. funiculata) and 11 of Sporormiella (S. affinis, S. commutata, S. grandispora, S. heptamera, S. kansensis, S. leporina, S. longisporopsis, S. megalospora, S. muskokensis, S. octomera and S. pulchella). Of these, the genus Sporormia and four species of the other genera (P. fleischhakii, S. affinis, S. commutata and S. longisporopsis) are newly recorded in Ukraine. For all fourteen species, their morphological characters are described, illustrated and discussed; occurrence records, habitat and distribution data are also provided. This study extends the distribution ranges of these fungi eastwards within Europe and contributes to their substrate list.

DELGADO G., KOUKOL O., HEREDIA G., PIEPENBRING M. (2020): Texas microfungi: Hermatomyces amphisporus (Pleosporales, Dothideomycetes) revisited.   [anamorphic ascomycete, phylogenetic placement, saprobic, taxonomy, genotypic variability, Hermatomyces bauhiniae.]  Czech Mycology 72(1): 95-107   (published: 22nd June, 2020)
  abstract   The pleosporalean anamorph Hermatomyces amphisporus is recorded for the first time from the U.S.A. based on several specimens collected on Sabal minor (Arecaceae) during mycological surveys carried out in the state of Texas. Phylogenetic analyses of novel DNA sequence data belonging to four nuclear regions (ITS rDNA, EF1-α, RBP2, β-TUB) revealed its taxonomic position within the monotypic family Hermatomycetaceae (Pleosporales, Dothideomycetes) in congruence with its morphological features. A description of the fungus in culture is provided here for the first time. Interestingly, apart from the lenticular conidia, also cylindrical conidia were formed together with chlamydosporous structures and pycnidia producing hyaline, nonseptate conidia. Further notes on the morphology on natural substrate, ecology and distribution in the U.S.A. and worldwide of this rare fungus are provided. The recently introduced species H. bauhiniae, which presents morphological characteristics different from the typical Hermatomyces spp., is found to be based on a confusing description, thus a different genus should be found to accommodate it.

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.

KOLAŘÍK M. (2018): New taxonomic combinations in endophytic representatives of the genus Nigrograna   [Biatriospora, taxonomy, endophytic fungi]  Czech Mycology 70(2): 123-126   (published: 28th September, 2018)
  abstract   Nigrograna (Ascomycota: Pleosporales), with the type species N. mackinnonii, has been considered a synonym of Biatriospora. Recently, it was shown that these two genera are distinct. In this study, four species earlier described in Biatriospora, i.e. B. antibiotica, B. carollii, B. peruviensis and B. yasuniana, which are phylogenetically related to N. mackinnonii, are combined in Nigrograna. Recently, three teams of authors published eight Nigrograna species almost simultaneously (2016–2017), thus some were not compared phylogenetically. A comparison of available sequences showed that all nine accepted species are unique. It can be concluded that Nigrograna is ecologically diverse, comprising species living as endophytes or saprobes of plants (some of them associated with other fungi living on those plants) as well as species living in marine or estuarine environments.Interestingly, all associations with vascular plants concern angiosperms.

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.

ABDEL-HAFEZ S.I.I., ABO-ELYOUSR K.A.M., ABDEL-RAHIM I.R. (2015): Leaf surface and endophytic fungi associated with onion leaves and their antagonistic activity against Alternaria porri.   [phyllosphere, phylloplane, endophytes, purple blotch disease, antagonism]  Czech Mycology 67(1): 1-22   (published: 10th April, 2015)
  abstract   Sixty-eight fungal species belonging to 29 genera were isolated as leaf surface and endophytic fungi from healthy and purple blotch diseased onion leaves. The fungal populations associated with diseased onion leaves (1.360 × 103 CFU/g leaf in the phyllosphere, 2.614 CFU/leaf segment in the phylloplane and 1.324 CFU/leaf segment in the surface-sterilised diseased leaves) were higher than those in healthy samples (0.804 × 103 CFU in the phyllosphere, 1.184 CFU in the phylloplane, and 0.35 CFU as endophytes). Endophytic fungi of healthy leaves were represented by 12 genera and 15 species, while fungi of surface-sterilised diseased leaves included 17 species from 13 genera. The mycobiota associated with surface-sterilised diseased leaves were different from the endophytic fungi of healthy samples, whereas the disease may stimulate colonisation of opportunistic fungi causing secondary infections such as Botrytis cinerea, Penicillium aurantiogriseum, Alternaria alternata and Cladosporium spp. In contrast, healthy leaves were a source of antagonistic endophytic fungi such as Trichoderma harzianum and T. koningii. Testing the antagonistic effect of 91 fungal isolates against Alternaria porri showed that nine isolates of Trichoderma produced the highest suppressive potential (73.1%) depending on competition and mycoparasitism. Epicoccum nigrum and Penicillium oxalicum exhibited antibiosis against A. porri producing a 12 mm broad inhibition zone. In conclusion, the quantitative and qualitative compositions of fungi associated with onion leaves were distinctly influenced by A. porri infection. Mycobiota associated with asymptomatic onion leaves such as Epicoccum nigrum, Penicillium oxalicum and Trichoderma harzianum are a natural source of eco-friendly bioagents. They showed an effective antagonistic potential against A. porri, and may thus be applied as an alternative to fungicides.

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.

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.
