(2016): Fungi and lichens recorded during the Cryptogam Symposium on Natural Beech Forests, Slovakia 2011. [old-growth beech forests, diversity, conservation, indicator, red-list, Europe] Czech Mycology 68(1): 1-40 (published: 1st February, 2016)
abstract
In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchy Mts., Oblík in the Slanské vrchy Mts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.
CABOŇ M., ADAMČÍK S. (2014): Ecology and distribution of white milkcaps in Slovakia. [Lactarius controversus, Lactifluus bertillonii, Lactifluus glaucescens, Lactifluus piperatus, Lactifluus vellereus, Slovakia, ecology, fungi, Russulaceae] Czech Mycology 66(2): 171-192 (published: 23rd December, 2014)
abstract
The study deals with the occurrence and ecology of five white milkcap species in Slovakia, Lactarius controversus, Lactifluus bertillonii, Lactifluus glaucescens, Lactifluus piperatus and Lactifluus vellereus. Recent molecular studies have shown that the reliability of field characters traditionally used for identification of white milkcaps is very low. Comparison of our field observations with microscopical analyses confirmed that the colour change of the latex is not a reliable feature to distinguish Lactifluus glaucescens and Lactifluus piperatus. An interesting result is the discovery that Lactifluus bertillonii was not recognised in the past (until 2013) and has been consistently misidentified as Lactifluus vellereus (8 herbarium specimens). Surprisingly, older specimens of Lactifluus glaucescens and Lactifluus piperatus, although well represented in the herbaria, were not frequently confused. Possible reasons are discussed.
JANČOVIČOVÁ S., ADAMČÍK S. (2014): Exploring the limits of morphological variability and ecological preferences of Entoloma albotomentosum. [Agaricales, morphology, ecology, Slovakia, Europe] Czech Mycology 66(2): 121-134 (published: 23rd December, 2014)
abstract
The first and so far only known collection of Entoloma albotomentosum from Slovakia is described and illustrated. Because of discrepancies between various published descriptions of the species, our collection is compared with the material originating from the type collecting site in Austria.According to our observations, both studied specimens are similar in having a thin pileipellis made up of dispersed and narrow hyphal terminations arranged in a cutis or a cutis with transitions to a trichoderm, presence of coralloid hyphae in the pileipellis and spores no shorter than 9 μm. The delimitation of the species, variously interpreted in the literature, is discussed. The knowledge of the occurrence, ecology and threat of E. albotomentosum in Europe is also summarised.
CABOŇ M., ADAMČÍK S., VALACHOVIČ M. (2013): Diversity of the family Russulaceae in the Scots pine forests of Záhorská nížina (SW Slovakia). [Scots pine, ectomycorrhiza, fungal diversity, Russulaceae, Pinus sylvestris] Czech Mycology 65(2): 179-191 (published: 20th December, 2013)
abstract
The species diversity of the family Russulaceae was studied at four representative sites located in forests dominated by Pinus sylvestris on sandy soils in the Záhorská nížina lowland in the years 2010–2012. The diversity varies from 7 to 10 species per site. There is a high variation in species composition and frequency rates between the studied sites. At all four sites, members of two Russulaceae genera were represented: Lactarius with two recorded species in total, while Russula with 19 species.The species diversity of Russulaceae in the area of Záhorská nížina is estimated based on data from the representative sites, revision of herbarium material, and published data. Nineteen species were identified in the studied herbarium material, and together with the data from the representative sites this amounts to a total of 27 Lactarius and Russula species associated with Pinus and reported from the area. Published reports on the occurrence of three more species of these two genera, reported to be associated with pine trees in the area, have not been confirmed.

abstract
Entoloma jahnii – a species of the Entoloma subgen. Claudopus, sect. Claudopus – is reported from Slovakia for the first time. Diagnostic characters are discussed, illustrated and compared with those of similar and/or misidentified Entoloma taxa, especially of E. byssisedum. Data on the ecology and occurrence of E. jahnii in Europe are provided.
PETERSEN R.H., HUGHES K.W., ADAMČÍK S., TKALČEC Z., MEŠIĆ A. (2012): Typification of three European species epithets attributable to Strobilomyces (Boletales). [nomenclature, Boletaceae, Agaricomycotina, taxonomy, typification] Czech Mycology 64(2): 141-163 (published: 7th December, 2012)
abstract
One of the most easily recognized genera of boletes is Strobilomyces, represented by taxa on most continents. At least in the Northern Hemisphere, early European species epithets are being applied to local taxa. Among these epithets in common use are S. strobilaceus and S. floccopus, sanctioned (as Boletus) by Fries. Contemporary with these is also Boletus strobiliformis, although not sanctioned. All three names, however, have been without acceptable type specimens, so identifications and diagnoses have remained insecure. This paper designates type specimens for these epithets as a prerequisite for accurate assessment of taxa. Comparison of morphological characters and sequences of ITS region of nrDNA gathered from type and additional material suggest existence of only a single European species, correctly named S. strobilaceus.

abstract
Two specimens from Germany and one from South Dakota, USA, were identified as Flammulina rossica during the examination of the München herbarium (M) material of the genus Flammulina.Micromorphological characters of these specimens are described and illustrated. The variability and delimitation of F. rossica is discussed and the knowledge of its distribution, ecology, morphology and biology is summarized.
RIPKOVÁ S., ADAMČÍK S., KUČERA V. (2007): New, rare and less known macromycetes in Slovakia II. [Ascotremella faginea, Hygrocybe laeta, H. russocoriacea, Melanotus phillipsii, Panellus violaceofulvus, Xylaria filiformis, occurrence, ecology] Czech Mycology 59(2): 185-199 (published: 28th December, 2007)
abstract
Data on ecology, occurrence and endangerment of six rare and/or less known macromycetes collected in Slovakia are given. Although described more than a hundred years ago, only recent collections of Ascotremella faginea are known from Slovakia. Hygrocybe laeta and H. russocoriacea are red-listed in most European countries. Melanotus phillipsii, so far known only from the Belianske Tatry Mts., is published from four other areas. A new host of Panellus violaceofulvus was found and Xylaria filiformis is considered an overlooked species.
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.
ADAMČÍK S., RIPKOVÁ S., ZALIBEROVÁ M. (2006): Diversity of Russulaceae in the Vihorlatské vrchy Mts. (Slovakia). [Russula, Lactarius, distribution, biodiversity, Slovakia, fungi] Czech Mycology 58(1-2): 43-66 (published: 10th August, 2006)
abstract
Russulaceae taxa were studied in selected (nine) localities in the Vihorlatské vrchy Mts. (Slovakia) in the years 2001–2003. The study was focused on their diversity, ecology and distribution. A total of 75 species were identified, from which four species, Lactarius romagnesii, Russula odorata, R. sericatula and R. zvarae, were not published from Slovakia before, and another eleven species are rare.
ADAMČÍK S., RIPKOVÁ S. (2004): First record of a Pseudobaeospora species from the Czech Republic. [fungi, Tricholomataceae, Pseudobaeospora] Czech Mycology 56(3-4): 239-246 (published: 22nd December, 2004)
abstract
During the fourth meeting of young mycologists in the Protected Landscape Area of Třeboňsko (16-19October2003) we found a taxon of the genusPseudobaeospora characterised by the absence of clamp-connections. Comparing our specimen with the two other European species with out clamp-connections, P. oligophylla (Singer) Singer and P. pillodii (Quél.) Wasser, we have come to the conclusion that our specimen does not fit either species. More specimens are needed for a definite delimitation of this presumably new taxon.
ADAMČÍK S., KUČERA V., LIZOŇ P., RIPKA J., RIPKOVÁ S. (2003): State of diversity research on macrofungi in Slovakia. [field research, overview, number of taxa, phytogeographical units, Slovakia] Czech Mycology 55(3-4): 201-213 (published: 22nd December, 2003)
abstract
Available published data on occurrence and distribution of macrofungi in Slovakia were collected and transferred into a database. Data reported in the checklist of Slovak fungi were complemented with additional data from published papers and books previously not included in the survey. The degree of knowledge of our mycoflora was extrapolated by comparing data in selected taxonomic groups and phytogeographical units, and is presented in schematic maps.
ADAMČÍK S. (2003): Russula faginea and similar taxa. [macrofungi, Russulales, taxonomy, Russula faginea] Czech Mycology 54(3-4): 177-191 (published: 23rd May, 2003)
abstract
A selection of five specimens of Russula faginea and very similar taxa was made, examined microscopically and compared. The studied material seems to be composed of two groups which differ in spore size, frequency of line connections among the spines of the spores and size and shape of the terminalcells of generative hyphaein the pileusepicutis. I consider the two groups to be taxa at the rank of species. The nomenclature of these two proposed species is discussed. The only valid names available for them are R. faginea and R. abietum. The types of these species names correspond probably to the two observed groups, but as I have not studied the type of R. abietum, I cannot conclude this for certain. R. faginea Romagnesi, nom. inval. is validated here.
