KUNCA V., ČILIAK M., LUPTÁK R. (2018): Fruitbody production of Hericium erinaceus and its distribution in Slovakia   [fructification, phenology, Quercus petraea, wood decay stage]  Czech Mycology 70(2): 211-224   (published: 14th December, 2018)
  abstract   The relationships between selected log parameters and occurrence of Hericium erinaceus fruitbodies as well as its phenological aspects and distribution in Slovakia were studied for the first time. The research was conducted with two datasets. The first dataset is based on 15-year monitoring of 20 oak logs with the aim to relate H. erinaceus preference to selected log variables. The other one comprises records obtained from 63 different localities in Slovakia. The monitoring data confirmed continual fruitbody production on the same dead log and at the same position for three consecutive years. Furthermore, the fruitbodies were observed for five continual years in the same section of a living oak tree trunk. Of the studied log characteristics, H. erinaceus showed preference for smaller log sizes. Based on the second dataset, the main fructification period is dated from August to November, but fruitbodies can be found until February. Logs with fruitbodies were predominantly classified into the initial wood decay stage (Stage 2). The majority (92%) of the localities were situated in areas with a mean annual temperature above 6 °C.

ADAMČÍK S., CHRISTENSEN M., HEILMANN-CLAUSEN J., WALLEYN R. (2007): Fungal diversity in the Poloniny National Park with emphasis on indicator species of conservation value of beech forests in Europe.   [wood-inhabiting fungi, indicator species, beech forests, biodiversity, Slovakia, macromycetes]  Czech Mycology 59(1): 67-81   (published: 28th June, 2007)
  abstract   This paper lists recent finds of macrofungi from the Poloniny National Park in Slovakia. The list contains data on the occurrence of 62 taxa of macrofungi, 35 of which are new to Poloniny, and 15 have not previously been recorded from Slovakia. Additionally, 17 rare species generally considered as threatened in large parts of Europe were found. The study increases the number of fungal indicator species proposed for assessment of the conservation value of European beech forests known from selected nature reserves in Poloniny. The results of this study combined with previously published data shows that Stužica and Rožok National Nature Reserves are the sites with the highest number of these indicator species in Europe.

GRYGANSKI A.P., KIRCHHOFF B., MOLITORIS H.P. (2000): Fruitbody quality and enzyme production of strains of Hericium erinaceus, an edible mushroom of medicinal relevance.   [Fruitbody colour, fruit body quality, Hericium erinaceum, laccase, tyrosinase]  Czech Mycology 52(3): 195-207   (published: 7th December, 2000)
  abstract   Cultivation experiments of 14 heterokaryotic strains of the edible and medicinally relevant mushroom Hericium erinaceus have shown a large variation in yield, quality and colour of the fruitbodies (Kirchhoff 1996). To determine the reasons for different fruitbody colours, phenoloxydases in the vegetative mycelium on agar and liquid media were investigated. It was shown that the colour of the fruitbodies correlates with the presence and activity of the phenoloxidase laccase. There is no correlation between fruitbody colour and presence of the phenoloxidase tyrosinase, responsible for browning of white button mushroom fruitbodies, Agaricus bisporus. The data obtained are important for selection or breeding of new H. erinaceus strains with good fruitbody qualities.

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.

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.

PASAILIUK M.V., SUKHOMLYN M.M., GRYGANSKYI A.P. (2019): Patterns of Hericium coralloides growth with competitive fungi.   [fungal interactions, direct confrontation, antagonism, xylotrophic fungi.]  Czech Mycology 71(1): 49-63   (published: 22nd May, 2019)
  abstract   Growth and morphological patterns of cultures were examined for two strains of Hericium coralloides during competitive colonisation of different nutrient media. The nutrient chemical composition of the medium was found to play an important role in the manifestation of antagonistic potencies of cultures. On the nutrient-poor Czapek medium with cellulose, radial growth of the monoculture was very slow. However, in triple confrontation cultures, the rate of substrate colonisation increased, and a positive effect on H. coralloides growth was observed. On all the examined media, Fomes fomentarius was consistently antagonistic to H. coralloides. The less suitable the medium for H. coralloides growth, the greater inhibitory effect was observed, but only in the combination of H. coralloides and F. fomentarius. This effect was observed for both strains of Hericium. Schizophyllum commune displayed both an antagonistic and a stimulating influence on H. coralloides, depending on the medium used and the strain of Hericium. The morphology of cultures H. coralloides 2332 and 2333 on media of different compositions in dual confrontation cultures was typical of the strains, but the colony growth was mostly uneven. The obtained results will be used to reintroduce native strains of Hericium coralloides into the ecosystem of Hutsulshchyna NNP. The interrelations between different fungi should be taken into account for successful colonisation of natural substrate.

  abstract   Held on the occasion of the 50th anniversary of the autonomous Mycological Department, National Museum, Prague (herbarium PRM, formerly a part of PR herbarium). The symposium takes place in Český Krumlov (south Bohemia, Czech Republic), a UNESCO World Heritage Site, and former residence of the aristocrat Schwarzenberg family who declared the famous Boubínský virgin forest a protected site in 1858. Two days of presentations are followed by excursions to the nearby Boubínský and Žofínský virgin forests, the best-preserved old-growth forests in the Czech Republic. The abstracts are arranged in alphabetical order according to the surname of the first (presenting) author.
