A was investigated using molecular data (ITS) and the lectotype and a supporting epitype are designated for Pluteus consequences for taxonomy, nomenclature and morpho- cervinus, the type species of the genus. The name Pluteus logical species recognition in these groups were evaluated. chrysophlebius is accepted as the correct name for the Conflicts between morphological and molecular delimitation species in sect. Celluloderma, also known under the names were detected in sect. Pluteus, especially for taxa in the P.admirabilis and P. chrysophaeus. A lectotype is designated cervinus-petasatus clade with clamp-connections or white for the latter. Pluteus saupei and Pluteus heteromarginatus, basidiocarps. Some species of sect. Celluloderma are from the USA, P. castri, from Russia and Japan, and apparently widely distributed in Europe, North America Volvopluteus asiaticus, from Japan, are described as new. A and Asia, either with (P. aurantiorugosus, P. chrysophlebius, complete description and a new name, Pluteus losulus,are A. Justo (*) N.
