HOLEC J., WILD J. (2011): Fungal diversity in sandstone gorges of the Bohemian Switzerland National Park (Czech Republic): impact of climatic inversion. [macromycetes, ecology, microclimate, boreal-montane fungi] Czech Mycology 63(2): 243-263 (published: 10th August, 2011)
abstract
The diversity of macrofungi in 8 sandstone gorges (narrow valleys bordered by sandstone walls, mostly covered by Picea forests with admixed Fagus, alt. 170–390 m) was assessed with respect to microclimatic data from 235 stations measuring temperature and soil moisture along the elevation gradient. In total, 253 species of macrofungi were found including some boreal-montane species, species preferring moist habitats and/or species of more or less natural vegetation. Microclimatically, the bottoms of gorges are significantly colder than their slopes and slope crests during the vegetation period (climatic inversion) and show higher soil moisture throughout the year. However, they are not significantly colder during the winter period and even show a higher average minimal temperature than the rest of gorges. Generally, bottoms of sandstone gorges function as „buffers“ maintaining a stable, humid and rather cold microclimate and enabling the occurrence of some boreal-montane fungi and species requiring humid conditions. Climatic inversion is a phenomenon markedly influencing the distribution of fungi in the landscape and enabling extrazonal occurrence of some species.
HOLEC J., ZEHNÁLEK P. (2020): Taxonomy of Hohenbuehelia auriscalpium, H. abietina, H. josserandii, and one record of H. tremula. [fungi, morphology, DNA study, ecology, distribution, Europe.] Czech Mycology 72(2): 199-220 (published: 8th October, 2020)
abstract
The taxonomy of Hohenbuehelia auriscalpium (Fungi, Basidiomycota, Pleurotaceae) and its putative synonym H. abietina is evaluated based on material from natural forests in the Czech Republic and Ukraine. The rare species H. josserandii is described in detail based on rich collections from Boubínský prales virgin forest in the Czech Republic. All specimens were studied both morphologically and molecularly (ITS and 28S nrDNA, EF1-α). The recently published conclusion that H. auriscalpium and H. abietina are conspecific was confirmed. The species grows on wood of deciduous trees as well as conifers. The thickness of the gelatinous pileus layer and the presence or absence of pileocystidia proved to be taxonomically irrelevant. One collection from the studied dataset significantly deviates by its DNA sequences and may represent a separate taxon close to H. auriscalpium. Another collection originally identified as H. auriscalpium turned out to be H. tremula. A higher range of some morphological characters was found in H. josserandii as compared with published data. The species prefers wood of Abies alba, namely branches of trees which fell 2–3 years ago.
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.
