Two new species of Pluteus collected in Kerala State (India) are described based on morphological and molecular (nrITS) characters. Pluteus brunneosquamulosus of sect. Celluloderma is characterized by the squamulose, ‘Lepiota-like’, pileus, subglobose to broadly ellipsoid spores, cheilocystidia with a long flexuous neck and lageniform or narrowly utriform caulocystidia. Pluteus velutinus belongs in sect. Hispidoderma and is unique in its shallowly depressed, hygrophanous, orange-brown, \velvety, squamulose pileus, the pleurocystidia very commonly provided with an apical digitate projection up to 10 μm long or tapering towards apex and the pileipellis as a trichoderm or trichohymeniderm. P. chrysaegis from India and P. conizatus var. africanus from Africa are considered synonymous based on morphological and molecular evidence.
