HOLEC J., KUNCA V., KŘÍŽ M., ZEHNÁLEK P. (2022): Cyphella digitalis (Fungi, Agaricales) – new data on ITS barcode, ecology and distribution in the Czech Republic and Slovakia. [Cyphellaceae, Abies alba, old-growth forests, substrate, phenology.] Czech Mycology 74(1): 77-92 (published: 22nd April, 2022) Electronic supplement
abstract
Records of Cyphella digitalis from the Czech Republic and Slovakia are summarised and discussed. ITS barcode of two collections was obtained to document their conspecificity with the only so far sequenced sample originating from the Alps. In the study area, C. digitalis is rare with ten localities known from the 20th century and nine recorded in the 21st century. They are situated in the Bohemian Forest and several mountain ranges of the Western and Eastern Carpathians. The elevation range of the records is 525–1200 m a.s.l. All records are from Abies alba, mostly branches attached to freshly fallen trunks and sticking out into the air. Basidiomata occur in Fagus-Abies or Fagus-Abies-Picea forests from September to March with a peak in September–November. Most stands represent old-growth forests under protection. Ecology and distribution are discussed in a broad European context. The much lower number of records in the Czech Republic and Slovakia compared to more western countries could have, among other things, also biogeographical reasons, i.e. decrease in occurrence with increasing continentality to the east.
KUNCA V., PEIGER M., TOMKA P., VAMPOLA P. (2022): Old-growth forest fungi – new localities and habitat and host preferences in Slovakia (I). [Amylocystis lapponica, Antrodia labyrinthica, Ionomidotis irregularis, Skeletocutis odora, Yuchengia narymica, decay stage, forest naturalness.] Czech Mycology 74(1): 33-55 (published: 28th February, 2022) Electronic supplement
abstract
“Old-growth forests” comprise habitats from untouched, primeval forests to partially man-influenced, near-natural forests. Some fungal species occur preferably in these forests with a high degree of naturalness. Occurrence data from Slovakia for five wood-inhabiting fungal species was processed. The numbers of known localities of these species in Slovakia range from 4 to 49. The five species prefer different stages of wood decay when producing fruitbodies. Records of the studied species indicate that Amylocystis lapponica and Ionomidotis irregularis occur only in old-growth forests, especially in the best-preserved virgin and natural ones, in Slovakia typically on wood of only one or two tree species. Antrodia labyrinthica occurs in natural and near-natural forests, while the remaining two species can survive in managed forests with a natural tree composition, localised close to forests of higher naturalness (Skeletocutis odora) or even in more intensively managed forests with a small amount of decaying wood and parks (Yuchengia narymica). The substantial increase in the number of records of some species in Slovakia can be related to more intensive research in montane old-growth forests (e.g. Amylocystis lapponica) or probably to a massive spread of species (Yuchengia narymica), even in a wide elevation range.
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.

(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.
KUNCA V. (2012): Boletus moravicus - ecological conditions of new localities in Slovakia. [red-listed species, ecology, pH values] Czech Mycology 64(2): 165-174 (published: 7th December, 2012)
abstract
Ecological conditions of four new localities where Boletus moravicus occurs are described. Oaks prevail in the studied forest communities. Our measurements of soil pH values showed that the localities, all on volcanic bedrock, have very acidic to mildly acidic soils. We can confirm the published fructification from July to October. Finds in Slovakia were recorded from altitudes of 210 m to 518 m a.s.l.mainly from Carpinion betuli forest communities.
KUNCA V. (2011): Ecology and incidence of Polyporus umbellatus in Slovakia. [Polyporus umbellatus, ecology, pH values, incidence, Slovakia] Czech Mycology 63(1): 39-53 (published: 10th August, 2011)
abstract
Research of the incidence of Polyporus umbellatus (Pers.) Fr. was carried out in 37 plots covering a diverse range of conditions in Slovakia. Based on measurements of soil pH values, this fungal species prefers acid soils. The highest number of sporocarps per plot during the three years of monitoring was detected every July. The majority of localities with incidence of P. umbellatus were located in hilly terrain, fewer in lowlands and very occasionally in uplands. Sclerotium and sporocarps predominantly occur at a specific distance from colonised beech, hornbeam and oak trees, with fewer individuals found in the vicinity of the host trees. Data from the research confirm that this species is well represented in Slovakia, nevertheless published data on its incidence and habitat are still rare.
