JANDA V., KŘÍŽ M., GRACA M. (2014): First records of Xerocomus silwoodensis (Boletaceae) in the Czech Republic. [Xerocomus silwoodensis, Boletaceae, description, ecology, Czech Republic] Czech Mycology 66(2): 135-146 (published: 23rd December, 2014)
abstract
The paper contains a report on the first collections of Xerocomus silwoodensis in the Czech Republic. The authors present a macro- and microscopic description of this species based on a study of material collected from one Bohemian and one Moravian locality. Characters distinguishing X. silwoodensis from related species of the genus Xerocomus Quél. s. str. (X. ferrugineus, X. subtomentosus, and X. chrysonemus) are discussed.
ŠUTARA J., JANDA V., KŘÍŽ M., GRACA M., KOLAŘÍK M. (2014): Contribution to the study of genus Boletus, section Appendiculati: Boletus roseogriseus sp. nov. and neotypification of Boletus fuscoroseus Smotl. [Boletus roseogriseus sp. nov., Boletus fuscoroseus, morphology, molecular phylogeny, neotypification, distribution] Czech Mycology 66(1): 1-37 (published: 4th June, 2014)
abstract
The paper deals with Boletus roseogriseus and Boletus fuscoroseus, two closely related species of the genus Boletus, section Appendiculati. B. roseogriseus is described as a new species based on a morphological and molecular study of collected material. B. fuscoroseus, validly published by Smotlacha in 1912, has been often incorrectly named Boletus pseudoregius. This name, however, does not have priority because B. pseudoregius was validly published as late as 1988. In order to contribute to clarification of some controversial questions concerning B. fuscoroseus, the authors have selected a neotype for this species. Descriptions of B. roseogriseus and B. fuscoroseus are accompanied by results of a molecular study (ITS and LSU rDNA sequences) and a discussion of characters distinguishing these species from other representatives of section Appendiculati.
HOLEC J., ANTONÍN V., GRACA M., MOREAU P.-A. (2003): Gymnopilus igniculus - find from the Czech Republic and notes on its variability. [fungi, Agaricales, Cortinariaceae, violet-coloured Gymnopilus, Europe, taxonomy, ecology, coal mine dumps] Czech Mycology 55(3-4): 161-172 (published: 22nd December, 2003)
abstract
Gymnopilus igniculus Deneyer, P.-A. Moreau et Wuilbaut (Agaricales, Cortinariaceae), a violet-coloured species described in 2002 from Belgium, was found in the city of Ostrava, part Radvanice, Czech Republic. The fruitbodies grew on decaying wood of Fraxinus in a unique habitat - a burning coal mine dump, the surface of which reached about 45'C. The most important characters of the fruitbodies are the purplish to vinaceous- or reddish-brown colour of the pileus covering which is tomentose-fibrillose when young and fibrillose-squamulose to distinctly scaly at maturity, they ellow pileus ground, the absence of any ring, the whitish membranaceous to fibrillose veil, the stipe distinctly longitudinally purplish brown fibrillose on the dirty white or slightly violaceous ground, the context yellowish with reddish-violaceous tinge and fungoid smell, there latively large spores [8.0-9.5(-ll) X 6.0-6.8(-7.2) fim] with rough verrucose to verrucose-rugulose ornamentation, the variable shape of cheilocystidia and the absence of pleurocystidia. A detailed description of macro- and microcharacters, colour photographs of fresh fruitbodies and line drawings are provided. Some characters deviating from the Belgian collections are discussed and remarks on other European finds of Gymnopilus with violet colours are added.
