In the explanation of the colored plate accompanying this issue, the author discusses the distribution of Cortinarius orellanus Fr. in Czechoslovakia. A specimen from North America, reported under the same name, is probably not identical with the European species. Even within Europe, taxa labeled as C. orellanus vary significantly, particularly in pigmentation. The systematic value of many segregates is thus unclear, and even the toxicology of C. orellanus remains unresolved. The second species illustrated, C. speciosissimus Kühner & Romagn., has not yet been found in Czechoslovakia.
