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.

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.

SANTIAGO K.A.A., DELA CRUZ T.E.E., TING A.S.Y. (2021): Diversity and bioactivity of endolichenic fungi in Usnea lichens of the Philippines.   [antibacterial, anticandidal, antioxidant, lichen-associated, Sagada.]  Czech Mycology 73(1): 1-19   (published: 14th January, 2021)   Electronic supplement
  abstract   Endolichenic fungi (ELF; asymptomatic microorganisms living inside healthy lichen thalli) were isolated from three Usnea species, namely U. baileyi, U. bismolliuscula and U. pectinata, collected near the town of Sagada, Philippines. A total of 101 ELF were recovered representing 12 genera (classes Sordariomycetes and Eurotiomycetes), with the genera Nemania (50.5%, 51 isolates) and Xylaria (22.8%, 23 isolates) being the most abundant. Comparative analyses on the antimicrobial activities of lichens and ELF revealed that lichen crude extracts were effective against the Gram-positive bacterium Staphylococcus aureus and the yeast Candida albicans, while ELF crude extracts were effective against S. aureus, C. albicans and the Gram-negative bacterium Escherichia coli. The broad-spectrum nature of ELF has provided medicinal and industrial advantages over the slow-growing lichens as shown on their respective bioactivities. Extracts from ELF also had a higher total flavonoid content (TFC; 6.29–85.69 mg QE/g of extract) and stronger antioxidant activities (IC₅₀: 0.57–19.63 mg/ml) than lichen-derived extracts. Although only culturable ELF were identified, this study provides the first evaluation of the diversity and bioactivities of culturable ELF from fruticose lichens of the genus Usnea in the Philippines.

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.

SAWMYA K., VASUDEVAN T.G., MURALI T.S. (2013): Fungal endophytes from two orchid species - pointer towards organ specificity.   [fungal endophytes, environment, orchids, Bulbophyllum neilgherrense, Pholidota pallida]  Czech Mycology 65(1): 89-101   (published: 10th June, 2013)
  abstract   Fungal endophytes may influence plant communities by altering the host’s fitness either positively or negatively. Little is known, however, about their host/organ specificity, life style and role in plantfungus symbiosis under varying environmental conditions. We compared the leaf and root endophyte assemblages of two orchids (Bulbophyllum neilgherrense and Pholidota pallida) from natural forests and greenhouse conditions. Xylariaceae species were consistently associated with leaf and root tissues, while Guignardia and Pestalotiopsis were found predominantly in the leaf tissues of both orchids. Correspondence analysis of the endophyte assemblages showed that the endophytes exhibited distinct organ but little host specificity. More endophytes were shared by the two different orchids growing in the same location when compared to endophyte assemblages of a single orchid from different locations. Considering the influence of endophytes in shaping the host’s community, diverse habitats must be screened vigorously to address questions regarding the role of endophytes in hostendophyte interactions.

  abstract   The present paper deals with new records of the heterobasidioid fungi Dacrymyces ovisporus Bref. and Tremella diaporthicola Ginns et M.N.L. Lefebvre in Europe. The taxonomical status of these species is considered and detailed descriptions and illustrations of specimens are given.

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.

PRÁŠIL K., ŠAŠEK V. (1977): Antibiotic activity of some Pyrenomycetes.  Česká Mykologie 31(1): 1-7   (published: 1st March, 1977)
  abstract   A set of cultures of stromatic lignicolous Pyrenomycetes was screened for antibiotic activity. From a total of 25 species (36 strains), the antibiotic activity was detected in 9 species. The most active species were Diaporthe impulsa, D. pustulata, Hypoxylon multiforme, Hypoxylon sp. and Valseutypella tristicha. However, the antibiotic activity lowered down in the course of re-inoculation, especially when the cultures were transferred into the submerged conditions. According to this finding, more appropriate test would be the direct screening of the submerged cultures.
