All species examined are described in detail and fully illustrated. Also a identification key to delimit the studied species is provided.

KUBIČKA J. (1973): Übersicht den bischer veröffentlichten Pilzarten aus dem Kubani Urwald (Boubín) in Böhmerwald.  Česká Mykologie 27(4): 212-228   (published: 1973)
  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., KOLAŘÍK M. (2017): First report of Mycena clavata (Fungi, Agaricales) in the Czech Republic including notes on its taxonomy, phylogenetic position and ecology.   [Europe, Boubínský prales virgin forest, Bohemian Forest, ITS-LSU rDNA sequences, Phloeomana]  Czech Mycology 69(1): 1-14   (published: 19th January, 2017)
  abstract   The rare gilled fungus Mycena clavata is reported from the Czech Republic for the first time. It was found on large fallen trunks of Picea abies in Boubínský prales virgin forest, the best preserved montane old-growth forest in the country. The basidiomata occurred in the lower half of the trunks, either on their upper or lateral sides, on bark covered by mosses, on bare bark, or directly on wood covered by mosses, in wet times of the year. Descriptions and photographs of macro- and microcharacters are provided and data on the distribution and ecology of M. clavata are summarised. The species was sequenced for the first time. ITS-LSU rDNA sequences confirmed the species’ distinct position and showed that M. clavata belongs to a moderately supported clade consisting of various Mycena and Hemimycena species, some of them recently transferred to the vaguely delimited genus Phloeomana.

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.

VAŠUTOVÁ M. (2004): Macromycetes of permanent plots in cultural forests in the Moravskoslezské Beskydy Mts. and Vsetínské vrchy hills (Czech Republic).   [Czech Republic, macromycetes, cultural beech and spruce forests, mycocoenology, permanent plots, ecology]  Czech Mycology 56(3-4): 259-289   (published: 22nd December, 2004)
  abstract   The mycoflora of cultural (artificial and managed subnatural) forests (i.e. beech, spruce and mixed forests) was studied in 18 permanent plots in the Moravskoslezské Beskydy Mts. and the adjacent part of the Vsetínské vrchy hills (Czech Republic) during they ears 1998-2000. Al together, 314 species of macromycetes were recorded. The highest number of species was recorded in plots in a young spruce forest on a former meadow (72 species ) and a waterlogged spruce forest (67 species ). Mycorrhizal fungi were the dominant group in older spruce forests (44.2 %), waterlogged spruce forests (43.3 %) and alder forest (45.6 %). A high percentage of terrestrial saprophytes was found in the young forest on a former meadow (43 %). Generally, common species prevailed.The main factor which influenced the species composition of all trophic groups was the composition of the tree layer. These results are compared with results from similar plots in the Czech Republic and neighbouring countries.

ANTONÍN V. (2003): A revision of the type specimens of new species of Delicatula (Agaricales, Tricholomataceae) described by Josef Velenovský.   [fungi, Agaricales, Tricholomataceae, Collybia, Delicatula, Hemimycena, Mycena, type studies, taxonomy, nomenclature]  Czech Mycology 54(3-4): 205-233   (published: 23rd May, 2003)
  abstract   The type specimens of 38 new species of the genus Delicatula Fayod described by Josef Velenovský were studied. Also the original notes and unpublished pencil drawings from the estate of J. Velenovský were used. All recognised species were taxonomically identical with already known species. As a nomenclatorical result, the following new combination is proposed: Hemimycena subtilis (Velen.) Antonin comb. nov. as the older name for a taxon known as Hemimycena cyphelloides (P. D. Orton) Maas Geest. (= Mycena pseudocrispula Kühner, forme bisporique).

MOREAU P.-A., COURTECUISSE R. (2003): Une réévaluation de Mycena radicifera J. Favre.   [Basidiomycota, Tricholomatales, Mycena radicifera, apogamie, variation intraspécifique, milieux xériques, taxinomie]  Czech Mycology 54(3-4): 161-175   (published: 23rd May, 2003)
  abstract   Mycena radicifera J. Favre est étudié sur la base de la récolte-type et de plusieurs récoltes récentes effectuées en France et au Groënl and . L’espèce apparaît caractéristique des milieux sablonneux à tendance nitrophile. L’existence de récoltes apogames est reconnue. La variabilité des caractères microscopiques: spores, cheilocystides, piléipellis est examinée. Le nom de M. radicifera var. apogama est proposé pour dénommer les for mes apogames, différant du type par la bisporie des basides, l’absence de boucles et la structure du suprapellis.

LAGANÀ A., SALERNI E., BARLUZZI C., PERINI C., DE DOMINICIS V. (2000): Mycocoenological studies in Mediterranean forest ecosystems: calcicolous deciduous oak woods of central-southern Tuscany (Italy).   [mycocoenology, calcicolous deciduous oak woods, Mediterranean]  Czech Mycology 52(1): 1-16   (published: 21st January, 2000)
  abstract   The results of mycocoenological studies carried out in calcicolous deciduous oak woods of central-southern Tuscany are reported. Comparison with there sults of studies in other for est ecosystems of the same area revealed exclusive differential species of deciduous oak woods and clarified the knowledge on mycocoenoses of central-southern Tuscany. The obtained in formation on individual species is also useful for understanding the relatively unexplored field of the ecology of macrofungi.

STERNER O., ANKE H. (1995): Toxic terpenoids isolated from higher fungi.   [Terpenoids, toxicity, biological activity, higher fungi, Basidiomycotina]  Czech Mycology 48(1): 39-52   (published: 16th May, 1995)
  abstract   A large number of toxic terpenoids have been isolated from cultures and fruit bodies of higher fungi. The chemistry, biological activity and possible natural functions of some of them are discussed in this paper. Especially interesting in this respect are natural defensive compounds that possess for example antibiotic and antifeedant activities and are likely to be toxic. The sesquiterpenoids of the pungent Lactarius species (e.g. L. necator, L. piperatus, L. rufus and L. vellereus) constitute an interesting example of this. In the fruit bodies of these species within seconds after a physical injury, an apparently inactive precursor is converted enzymatically into a range of pungent sesquiterpenes with an unsaturated dialdehyde functionality possessing potent antimicrobial and cytotoxic activities. The injury brings the precursor, which is present as an emulsion in the latex of specialised hyphae of the fruit bodies, in contact with the enzyme systems that are kept apart in the intact fruit body. Fruit bodies of non-pungent and edible Lactarius species (e.g. L. deliciosus and L. flavidulus) contain precursors with completely different chemical structures that also are converted as a response to injury, although to products with less striking biological activities and with uncertain function.

SVRČEK M. (1990): A report on mycological trips to Krkonoše Mts. (Giant Mts.), Bohemia, in the years 1986-1989.  Česká Mykologie 44(2): 77-91   (published: 22nd June, 1990)
  abstract   The results of mycological trips undertaken by me in the years 1986–1989 to the east part of the highest Bohemian mountains are published in this paper. At present, Krkonoše Mts. (Giant Mts.), the only one National Park (KRNAP) in Bohemia, belong to the most damaged territories by air pollution (SO₂) and acid rainfalls. The excursions were realized every year in August and September. In this time the fructification of macromycetes is maximal. The fungi were collected in more than 70 localities often repeatedly, with special regard to Agaricales, Aphyllophorales and Ascomycetes, occasionally also to other groups, and most attention was paid to their ecology. The species of Agaricales examined and determined hitherto are alphabetically arranged and supplemented by numbers of records according to years, localities and altitude above sea level. The ecological and taxonomic notes will be published in the second and third part of this report.

POUZAR Z. (1983): Taxonomic and nomenclatural notes on some families of larger fungi.  Česká Mykologie 37(3): 172-176   (published: 1983)
  abstract   The illegal status of family names published with vernacular termination is discussed. Six families which are devoid of names agreeing with nomenclatural Code are treated and provided here with validation diagnoses or other necessities: Amanitaceae Heim, Asterostromataceae (Donk) Pouz., Coprinaceae Heim, Cortinariaceae Heim, Faerberiaceae Pouz. and Tricholomataceae Heim.

KOTLABA F. (1981): Excursio mycologorum Bohemicorum in Karlštejn anno 1980.  Česká Mykologie 35(2): 108-111   (published: 1981)
  abstract   A mycological excursion to Karlštejn in 1980 is reported. Due to dry weather, few fungi were found. A complete list of all observed species is published, including common ones, unlike previous reports that listed only rare taxa.
