ADAMČÍK S., RIPKOVÁ S., ZALIBEROVÁ M. (2006): Diversity of Russulaceae in the Vihorlatské vrchy Mts. (Slovakia). [Russula, Lactarius, distribution, biodiversity, Slovakia, fungi] Czech Mycology 58(1-2): 43-66 (published: 10th August, 2006)
abstract
Russulaceae taxa were studied in selected (nine) localities in the Vihorlatské vrchy Mts. (Slovakia) in the years 2001–2003. The study was focused on their diversity, ecology and distribution. A total of 75 species were identified, from which four species, Lactarius romagnesii, Russula odorata, R. sericatula and R. zvarae, were not published from Slovakia before, and another eleven species are rare.
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.
ADAMČÍK S. (2003): Russula faginea and similar taxa. [macrofungi, Russulales, taxonomy, Russula faginea] Czech Mycology 54(3-4): 177-191 (published: 23rd May, 2003)
abstract
A selection of five specimens of Russula faginea and very similar taxa was made, examined microscopically and compared. The studied material seems to be composed of two groups which differ in spore size, frequency of line connections among the spines of the spores and size and shape of the terminalcells of generative hyphaein the pileusepicutis. I consider the two groups to be taxa at the rank of species. The nomenclature of these two proposed species is discussed. The only valid names available for them are R. faginea and R. abietum. The types of these species names correspond probably to the two observed groups, but as I have not studied the type of R. abietum, I cannot conclude this for certain. R. faginea Romagnesi, nom. inval. is validated here.
