Observations on species of Pluteus from Idaho, U.S.A.
Pluteus (Agaricales, Basidiomycota) is a cosmopolitan eugaric genus characterized by free lamellae, pinkish brown basidiospores (in mass), convergent lamellar trama, and the lack of a universal veil as well as its typically xylophilic habit. During the recent NAMA foray in Idaho, U.S.A., some new collections of Pluteus were obtained. Data from morphological examinations and DNA sequences (ITS region & nLSU rRNA gene) suggest these represent undescribed taxa. Historically, these taxa may have been confused with Pluteus cervinus, a lumping ground of wide ranging degrees for superficially similar taxa. Descriptions and illustrations of these Idaho collections are presented.
