Two new species of Pluteus, P. densifibrillosus and P. puttemansii, are described and illustrated from specimens collected in two remnants of the Atlantic forest in the city of São Paulo, SP, Brazil. Pluteus densifibrillosus is characterized by a densely fibrillose pileus with spinulose fibrils at the center and almost globose basidiospores. Pluteus puttemansii has a stipe with a grayish brown subbulbous-marginate base and a strigose basal mycelium. Pluteus densifibrillosus belongs to section Hispidoderma and P. puttemansii to section Pluteus. Pluteus longistriatus and P. umbrinoalbidus, which were collected in the same area, also are described and illustrated. Pluteus longistriatus represents a new record for Brazil.
本文描述并图示了两种新的 Pluteus 物种，即 P. densifibrillosus 和 P. puttemansii，它们均来自于巴西圣保罗市两个大西洋森林遗迹中的标本。P. densifibrillosus 的特征是菌盖具有密集的纤毛状绒毛，中央有刺状的绒毛，并且担孢子几乎呈球形。P. puttemansii 的菌柄基部为灰棕色，具有亚鳞片状边缘，基生菌丝具糙丝状。P. densifibrillosus 属于 Hispidoderma 节，而 P. puttemansii 属于 Pluteus 节。本文还描述并图示了在同一地区采集的 P. longistriatus 和 P. umbrinoalbidus。P. longistriatus 是巴西的一个新记录。
