A new record of the rare agaric species Gymnopilus stabilis from the Czech Republic is described morphologically and genetically. The basidiomata show good agreement with the recently published epitype and diagnostic characters of the species. While the robustness of the basidiomata, the presence of a pink hue, and a distinct sweetish aromatic smell are typical characters, though not always present, the predominantly warm orange colour of adult pilei seems to be stable character. The combination of fleshy basidiomata and typical pileus colour distinguishes G. stabilis from G. penetrans/hybridus and G. decipiens, which are taxa sometimes confused with G. stabilis. Comparison of the nearest ITS rDNA sequences from GenBank confirmed the identity of our record and showed that the species is distributed not only in Europe and Siberia, but also in Pakistan and India. The ecological characterisation of G. stabilis is updated, showing that it is a saprotrophic species on dead wood of conifers, both Pinus and Picea, but also a facultative anthracophilous fungus able to grow on burnt wood and ash.
