[Basidiomycota, distribution, ecology, naturalness, nature conservation, Czech Republic, Slovakia, ITS, taxonomy.] Czech Mycology 75(1): 35-52 (published: 4th May, 2023) Electronic supplement
abstract
The distribution and ecology of Mycena laevigata was evaluated in the Czech Republic and Slovakia. We collected data on records from 32 Czech and 32 Slovak localities, mostly from dead wood of spruce, but also fir and rarely pine. Mycena laevigata is a distinctly submontane to supramontane species with its distribution peak in the montane zone and rare occurrence in the subalpine zone. Preferred habitats are supramontane spruce forests, submontane/montane mixed forests (beech, spruce, fir) and submontane beech/fir forests. Several extrazonal habitats are known, namely waterlogged spruce forests, bog forests and ravine forests. Records of M. laevigata clearly dominate in old-growth forests under protection, which are rich in dead wood of spruce and/or fir, while records from managed forests are extremely rare. The species is able to fructify on wood of all decay stages, but most frequently at advanced stages, from May to November, with peaks in June and September. The prevailing occurrence in old-growth forests shows that the species requires not only presence of dead conifer wood in any cold and humid environment, but also some degree of habitat continuity, i.e. minor human impact on the forest ecosystem. The species can therefore be used as a good indicator of habitat preservation. Its taxonomic identity was verified molecularly using the ITS sequence from Czechia. Sequences of Asian samples are somewhat different from the European ones. Its distribution in Europe is summarised and its ecology in other parts of Europe discussed.
VAŠUTOVÁ M., DVOŘÁK D., BERAN M. (2013): Rare macromycetes from raised bogs in the Hrubý Jeseník Mts. (Czech Republic). [macrofungi, peatland, raised bog, distribution] Czech Mycology 65(1): 45-67 (published: 10th June, 2013)
abstract
During a mycobiota study of raised bogs in the Hrubý Jeseník Mts., the rare fungi Omphaliaster borealis, Galerina sphagnicola, Clavaria argillacea var. sphagnicola, Ramariopsis subarctica and Ascocoryne turficola were found. Descriptions and figures of microscopic characters, photos and a summary of the knowledge on the ecology and distribution of these species in Europe, and a brief comparison with similar species are given. The boreo-alpine species Omphaliaster borealis is reported from the Czech Republic for the first time. It can be confused with Arrhenia onisca in the field. Another species new to the Czech Republic, the strictly sphagnicolous Galerina sphagnicola, can be overlooked and confused with several other sphagnicolous Galerina species. The newly reported variety of Clavaria argillacea, var. sphagnicola, is distinguished from the nominate variety by shape and size of its spores, as well as its habit and ecology. Ramariopsis subarctica was known in the Czech Republic so far only from the Giant Mts. (Krkonoše). Within Europe, the two Czech localities, along with a find in the High Tatra Mts. (Slovakia), are the only ones known outside Fennoscandia. Ascocoryne turficola is reported from Moravia for the first time.
ANTONÍN V., BERAN M., BOROVIČKA J., DVOŘÁK D., HOLEC J. (2011): Clitocybula familia (Fungi, Agaricales) - taxonomy, distribution, ecology and first records in the Czech Republic and Slovakia. [var. familia, var. compressa, DNA studies, Europe, North America, old-growth forests, bioindication] Czech Mycology 63(1): 1-11 (published: 10th August, 2011)
abstract
The first records of Clitocybula familia from the Czech and Slovak Republics were studied and compared with the type specimen of C. familia var. compressa and several North-American collections of var. familia using macro– and microscopic characters as well as molecular data (LSU rDNA).All the collections were identical. Therefore, there is no need to recognise var. familia and var.compressa, as they represent the same taxon. Detailed macro– and microscopic descriptions are given.In Europe, the species grows on strongly decayed fallen trunks of Abies alba and Picea abies. All four Central-European localities represent valuable old-growth forests. Therefore, this species may be a bioindicator of such environments.
ANTONÍN V., BERAN M., DVOŘÁK D., HOLEC J. (2009): First records of Callistosporium pinicola in the Czech Republic and new findings on its ecology. [Callistosporium pinicola, taxonomy, distribution, bioindication, Ukraine] Czech Mycology 61(1): 1-12 (published: 29th September, 2009)
abstract
Callistosporium pinicola has been collected at ten localities in the Czech Republic. They represent the first records in this country. Three finds from Ukraine are published as well. Detailed macro– and microscopic descriptions of the species are provided. C. pinicola grows on strongly decayed fallen trunks of Abies alba and Picea abies, however, it has once also been found on a frondose tree. Its preference for old-growth forests with spruce and fir in the Czech Republic is discussed, including its possible usage as a local bioindicator of such forests. It is very interesting that all collections of C. pinicola in the Czech Republic are recent (collected in the period 2004–2008). It suggests that the species is spreading for unknown reasons. In Europe, C. pinicola usually occurs in localities fulfilling two conditions: a humid climate and strongly decayed wood.
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.
