SOUČEK J., HOLEC J., BOROVIČKA J., DVOŘÁK D., FORMAN P., HROUDA P., KOLAŘÍK M. (2025): A DNA-based checklist of the stipitate hydnoids (Bankeraceae s.l.) of Czechia. [Thelephorales, ITS, LSU, taxonomy, ecology, GlobalFungi, Czech Republic.] Czech Mycology 77(1): 37-88 (published: 24th June, 2025) Electronic supplement
abstract
Based on a long tradition of field research aimed at this group, stipitate hydnoid fungi belong to the best explored macromycetes in Czechia. However, following groundbreaking taxonomic changes emerging from recent molecular studies, previous knowledge of particular taxa and their features has been questioned. To resolve this issue, selected specimens of Czech hydnoids were sequenced to confirm their identity. Generally, the presence of 39 taxa of Boletopsis, Hydnellum, Phellodon, and Sarcodon in the Czech Republic was confirmed, including the recently described species Boletopsis mediterraneensis, Hydnellum bomiense, H. fagiscabrosum, H. rubidofuscum, Phellodon aquiloniniger, P. castaneoleucus, and two so far undescribed taxa of Boletopsis and Hydnellum, as well as the recently reported Hydnellum gracilipes, H. illudens, Phellodon secretus and Sarcodon quercinofibulatus. Ecological requirements of newly delimited species are specified based on collection data from Czech localities, and GlobalFungi data are presented to supplement the current knowledge of the global distribution of particular species. Taxonomic issues, identification limits in species complexes, ecology, and threats to the species are discussed in relevant cases. Several more species, documented from or probably present in Czechia but not sequenced yet, are commented as well.
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.
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.
KLÁN J., ŘANDA Z., BENADA J., HORYNA J. (1988): Investigation of non-radioactive Rb, Cs, and radiocaesium in higher fungi. Česká Mykologie 42(3): 158-169 (published: 12th August, 1988)
abstract
The concentration factors for non-radioactive Rb, Cs, and radiocaesium in the fruit bodies of mushrooms were determined. The difference between the concentration factors of non-radioactive and radioactive Cs from the last fallout was one order of magnitude. No significant differences were found between the concentration factors of stable Rb and Cs for mushrooms and vascular plants. The highest accumulation of radiocaesium was observed in Boletus spp., Laccaria spp., Paxillus involutus, Cortinarius armillatus, and Lactarius rufus. The contribution of older weapon-test fallout and the more recent 1986 Chernobyl fallout could be differentiated by isotopic ratio. The radiation dose from consumption of 10 kg fresh mushrooms did not exceed 20% of the dose from natural background radiation in Czechoslovakia.
MICKA K., KLÁN J. (1980): Chemical spot tests of macromycetes with benzidine. Česká Mykologie 34(2): 74-81 (published: 1980)
abstract
Macrochemical colour reactions of benzidine were studied mainly with the species of genera Agaricus, Amanita, Lactarius, Russula, and Tricholoma. With the genus Lactarius, differences were found between the reactions of the milk and the context. Oxidation enzymes, which give a blue-green, blue, or black reaction, were detected in many species of the genera Agaricus, Lactarius, and Russula, whereas with Amanita and most species of Tricholoma they were absent. In the case of the genus Russula, only species with a burning taste give a yellow or ochre reaction. The reactions of benzidine are suitable as complementary characteristics for the determination of some mutually similar species.
HERINK J. (1965): Der Riesen-Ritterling, Tricholoma colossus (fr.) Quél. In der Tschechoslowakei (tab. 59). Česká Mykologie 19(4): 197-200 (published: 18th October, 1965)
abstract
The Swedish mycologist E. M. Fries described the mushroom Tricholoma colossus in 1836 as remarkable for its large size and tough flesh. He called it “maximus et durissimus Agaricus in orbe” – the largest and hardest gilled fungus in the world. Later detailed descriptions and illustrations confirmed this species, which has been found sporadically across Europe. The first correct report in Czechoslovakia is credited to R. Veselý in 1930. An earlier mention by J. Velenovský (1920) is considered a misidentification, possibly of Hygrophorus russula. The paper reviews past reports and confirms T. colossus as rare but valid in the region.
