Abstract

Two species of Pluteus, namely P. brunneoalbus and P. sepiicolor, from China are reported and illustrated. Pluteus brunneoalbus is described as a new species in P. sect. Celluloderma. This species is characterized by a shallowly depressed pileus, a white stipe, ellipsoid to broadly ellipsoid basidiospores 67  56.5μm, the presence of few scattered cheilocystidia, the presence of mostly clavate pleurocystidia, and a cutis type pileipellis. In the phylogenetic analysis based on the internal transcribed spacer region (ITS), the new species appears as sister to P. hirtellus and P. squarrosus. In addition to the new species, another species, P. sepiicolor, is reported here as a new record for China. Molecular data support its conspecificity with a collection from Russia. Detailed morphological descriptions including illustrations of the two species from China, and their comparisons with the related taxa of Pluteus are also provided with phylogenetic placement.
