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.

RAMSHAJ Q., RUSEVSKA K., TOFILOVSKA S., KARADELEV M. (2021): Checklist of macrofungi from oak forests in the Republic of Kosovo.   [fungi, taxa, Balkan Peninsula, diversity, ecology, rare species.]  Czech Mycology 73(1): 21-42   (published: 12th February, 2021)   Electronic supplement
  abstract   In the period from 2017 to 2019 a survey of the diversity of fungi in oak forests in the Republic of Kosovo was conducted. The survey included 31 localities, mainly in Quercetum frainetto-cerris and Querco-Carpinetum orientalis communities. As a result of the fieldwork performed in various seasons, a first checklist of fungi from oak forests in the country is provided. A total of 220 taxa (219 species and one forma) were identified. The majority of the identified taxa belong to Basidiomycota (206) and only 14 species to Ascomycota. The paper provides a list of all recorded species with data on locality, altitude, time of collection, forest association and type of substrate. Distribution and ecology of selected rare or threatened species are briefly discussed.

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.

ZOTTI M., PAUTASSO M. (2013): Macrofungi in Mediterranean Quercus ilex woodlands: relations to vegetation structure, ecological gradients and higher-taxon approach.   [conservation biology, ectomycorrhiza (ECM), fungal diversity, multivariate analysis]  Czech Mycology 65(2): 193-218   (published: 20th December, 2013)
  abstract   Few studies have investigated the relationships between mycodiversity and plant communities in Quercus ilex (holm oak) woodlands. These are unique ecosystems in the Mediterranean basin of high mycological importance. The macrofungi of Q. ilex forests in Liguria, North-Western Italy, were studied: 246 species were observed in 15 permanent plots over four years. Some species were identified as typical of holm oak woodlands, e.g. Hygrophorus russula, Leccinellum lepidum, and Lactarius atlanticus.Correspondence analysis (CA) showed that the main ecological gradients shaping the fungal and plant communities are driven by soil pH and climatic factors. The CA confirms that the minimum sampling area for macrofungi is larger than for plant communities and that aggregation of multiple plots is suitable for data analysis. The data suggest that the higher-taxon approach can be successfully applied also to Q. ilex macrofungi, not only for total species and genus richness, but also within abundance classes. Further investigations are required to better characterise the mycodiversity of Mediterranean holm oak woodlands in relation to human impacts over various scales to plan effective conservation strategies.

ANTONÍN V., LEGON N.W. (2008): Gymnopus obscuroides (Agaricomycetes, Omphalotaceae), a new species of sect. Levipedes from England.   [Agaricales, Omphalotaceae, Alkalivirentes, Gymnopus obscuroides, new species, England]  Czech Mycology 60(1): 13-19   (published: 4th July, 2008)
  abstract   A new species, Gymnopus obscuroides Antonín & Legon (Agaricomycetes, Omphalotaceae), is described. It is characterised by having a very long, floccose stipe, an initially dark purplish-brown then more mahogany-brown pileus, pallid pinkish-beige lamellae, rather large, subfusoid, ellipsoid-fusoid, lacrimoid to pip-shaped basidiospores, cylindrical, clavate, (sub)fusoid, subutriform, regular, irregular to subcoralloid cheilocystidia, a pileipellis consisting of radially arranged, cylindrical, scatteredly diverticulate, cylindrical, narrowly clavate or narrowly lageniform caulocystidia, and distinctly incrusted ochraceous-brown (in H O) hyphae, these becoming brown-olivaceous in KOH. It belongs to 2 sect. Levipedes (Fr.) Halling, subsect. Alkalivirentes Antonín & Noordel.

  abstract   Rhodocollybia giselae Neville & Antonin is described as a new species from the Mediterranean region of Europe (Italy, France). It grows in thermophilous forests with Quercus ilex, Arbutus unedo and Pinus. Its features and differences from other members of the R. butyracea group are discussed.
