KUČERA V., DVOŘÁK D., FEDOSOVA A.G., FULJER F. (2023): First record of earth tongue Hemileucoglossum pusillum (Geoglossales) in the Czech Republic.   [Ascomycota, Geoglossaceae, Řeka Nature Reserve, fen meadows, distribution.]  Czech Mycology 75(2): 179-190   (published: 13th December, 2023)
  abstract   In 2015, during a visit to Řeka Nature Reserve, an interesting earth tongue fungus was found in a fen meadow. It was later identified as Hemileucoglossum pusillum, a recently described species. Its occurrence on the site was also confirmed in 2021, when abundant material was collected. In the Czech Republic, it is the only known locality of this rare species, previously reported from Slovakia, Norway and Spain only. Its identity was verified both morphologically and molecularly by sequencing the ITS and LSU regions of nuclear ribosomal DNA. Its macro- and microscopic characters are presented and the variability, distribution, ecology and phenology of the species are discussed. A Czech name is proposed for the species.

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.
