SINGER R., KUTHAN J. (1980): Comparison of some lignicolous white-spored American agarics with European species. Česká Mykologie 34(2): 57-73 (published: 15th April, 1980)
abstract
Hypsizygus tessulatus (Bull. ex Fr.) Sing. is redescribed from American material and compared with some European data on this species. Description of three European species of the Hohenbuehelia petaloides group are provided and slight differences between European and American collections of H. petaloides are pointed out. It is suggested that a species typified by a Mexican collection, H. recedens spec. nov., may be part of Ricken’s concept of Pleurotus geogenius. H. portegna is described from both American and European collections and closely related species are discussed. Pseudoclitocybe beschidica spec. nov. is compared with European and American representatives of this genus. Since the type species of Nothopanus must be transferred to Pleurotus, the European representative of this genus has to be known (again) as Pleurocybella porrigens (Pers. ex Fr.) Sing.
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.
AL-TOUBI A.S.S., AL-SADI A.M., AL-MAHMOOLI I.H., AL-HARRASI M.M.A., AL-SABAHI J.N., VELAZHAHAN R. (2022): Volatile organic compounds emitted by mycoparasitic fungi Hypomyces perniciosus and Cladobotryum mycophilum suppress the growth of Agaricus bisporus. [antifungal, cobweb, ethanol, wet bubble, white button mushroom.] Czech Mycology 74(2): 141-152 (published: 14th November, 2022)
abstract
Hypomyces perniciosus and Cladobotryum mycophilum are mycoparasitic fungi infecting Agaricus bisporus and causing wet bubble and cobweb diseases, respectively. In this work, the role of volatile organic compounds (VOCs) emitted by these fungal mycoparasites in the suppression of A. bisporus was investigated. The VOCs of H. perniciosus and C. mycophilum effectively reduced the mycelial growth of A. bisporus by 60% and 73% after 5 days of incubation, respectively, compared to that of the control as assessed by the two-sealed-base-plates assay. Further, the VOCs of H. perniciosus and C. mycophilum were collected in a headspace solid-phase microextraction procedure, and their components analysed by means of gas chromatography-mass spectrometry. Ethanol was identified as the major volatile component in H. perniciosus and C. mycophilum. Ethanol vapour significantly retarded the growth of A. bisporus in an in vitro assay. The results of this study suggest that ethanol produced by H. perniciosus and C. mycophilum could be involved in the suppression of A. bisporus.
PRYDIUK M.P., LOMBERG M.L. (2021): First record of Coprinopsis strossmayeri (Psathyrellaceae) in Ukraine: morphological and cultural features. [Basidiomycetes, Agaricales, SEM, mycelium, morphological characteristics, growth rate.] Czech Mycology 73(1): 45-58 (published: 25th February, 2021)
abstract
The article presents data on the first record of the rare wood-rotting species of the Coprinopsis strossmayeri aggregate in Ukraine. A full description of its macro- and micromorphological features as well as an original drawing are provided. Morphological characters and data on mycelial growth on different agar media are reported. The growth optimum was observed on compost agar medium. Mycelial colonies of C. strossmayeri are white, cottony, very dense with fluffy aerial mycelium growing in concentric zones. Colonies have a characteristic yellow pigmentation and stain the agar yellowish. Microscopic features of vegetative mycelia are described. In the mycelium of C. strossmayeri, spherical structures inside storage hyphae, clamp connections, anastomoses, chlamydospores, and crystals on hyphae were observed.
HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi. [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution] Czech Mycology 67(2): 157-226 (published: 10th September, 2015)
abstract
Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.

abstract
The illegal status of family names published with vernacular termination is discussed. Six families which are devoid of names agreeing with nomenclatural Code are treated and provided here with validation diagnoses or other necessities: Amanitaceae Heim, Asterostromataceae (Donk) Pouz., Coprinaceae Heim, Cortinariaceae Heim, Faerberiaceae Pouz. and Tricholomataceae Heim.
