HOLEC J., BERAN M. (2007): Distribution, ecology and fructification of a rare ascomycete, Pseudorhizina sphaerospora, in the Czech Republic and its habitats in Europe.   [natural forests, virgin (primaeval) forests, man-made habitats, cold climate, mountains]  Czech Mycology 59(1): 51-66   (published: 28th June, 2007)
  abstract   Pseudorhizina sphaerospora (Ascomycota, Pezizales, Discinaceae) belongs to the rarest fungi of the Czech Republic (CR). At each of the three known localities its occurrence is quite different in character. There is a historical locality where the species was observed only once a long time ago (Plešný = Plechý Mts.), a locality with continuous occurrence for more than 80 years (Boubínský prales virgin forest) and a new locality, where the fungus was found in 2005 (Žofínský prales virgin forest). All records of P. sphaerospora in the CR originate exclusively from montane virgin forests representing rare remnants of natural vegetation almost untouched by man. However, in Nordic countries, Switzerland, Germany and Slovakia the species is known from man-made or man-influenced habitats. It seems that P. sphaerospora does not prefer natural forests but either cold and humid climatic conditions or dead wood with a stable high water content. Such conditions are met in Nordic countries, in high mountains, in virgin forests with a stable humid mesoclimate and in dead conifer woods supplied by water from streams, etc.

  abstract   A comprehensive overview of fungal species published from the Boubín primeval forest in the Šumava mountains is presented. The author compiled records from ca. 50 mycological excursions since 1906 and integrated them with modern taxonomy. This basic inventory serves as a foundation for future studies of fungal succession in this protected forest.

HOLEC J., ZEHNÁLEK P. (2021): Remarks on taxonomy and ecology of Dentipratulum bialoviesense based on records from Boubínský prales virgin forest in the Czech Republic.   [Fungi, Basidiomycota, Russulales, Auriscalpiaceae, ITS rDNA, natural forests.]  Czech Mycology 73(2): 121-135   (published: 1st July, 2021)
  abstract   Two recent records of the rare fungus Dentipratulum bialoviesense from Boubínský prales virgin forest in the Czech Republic were documented morphologically and molecularly. One collection from the type locality, Białowieża virgin forest in Poland, was used for morphological comparison.The Boubínský prales collections agree with the Białowieża collection in macro- and micromorphological characters and ecology, namely their growth on decaying wood of Picea abies in natural forest. Simultaneously, Boubínský prales collections clearly differ in their ITS rDNA region from the only published Dentipratulum sequence based on a collection from France, originally identified as D. bialoviesense but currently representing a paratype of the recently described species D. crystallinum. Consequently, the Boubínský prales sequences most likely represent the first sequence data of D. bialoviesense. Notes on the taxonomy and ecology of D. bialoviesense and D. crystallinum are added, suggesting that the identity of all collections should be verified molecularly in future, especially those from wood of broadleaved trees in France. Photographs of dried basidiomata and key micromorphological characters of D. bialoviesense from Boubínský prales and Białowieża are provided.

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.

Abstracts of the International Symposium „Fungi of Central European Old-Growth Forests“.  Czech Mycology 67(1): 95-118   (published: 18th June, 2015)
  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.

  abstract   The author examines the occurrence of leaf spot disease on chestnut (Castanea) in Slovakia, caused by the conidial stage of Mycosphaerella maculiformis (syn. Cylindrosporium castaneae). Symptoms, economic significance, and spore morphology are described based on samples from 12 localities. Suggested protective measures are also presented.

SVRČEK M., MORAVEC J. (1972): Über die Helvella fastigiata Krombholz (Farbtafel Nr. 81).  Česká Mykologie 26(1): 1-8   (published: 27th January, 1972)
  abstract   This paper deals with the taxonomy of Helvella fastigiata Krombholz = Gyromitra fastigiata (Krombh.) Rehm. This species was several times recently found in Europe and erroneously identified as the North American Neogyromitra caroliniana (Bose ex Fr.) Imai. The European collections, published under this name, are identical with the true Helvella fastigiata Krombholz, which was macroscopically well described and illustrated by its author in 1834. The type species of Krombholz remained unknown or misunderstood by most mycologists. A number of new collections made in 1971 in Moravia (Czechoslovakia) contributed to the clarification of this species, which belongs to the group of discomycetes placed in the genera Neogyromitra and Discina. Because — in the opinion of the authors — no essential differences between both genera exist, Helvella fastigiata is transferred to the genus Discina. With Discina fastigiata are identical: Gyromitra pratensis Velen., G. inflata sensu Velen., and Discina brunnea (Underw.) Raitviir.
