Two new species of Calliderma, C. fibulatum and C. rimosum, collected in fragments of the Atlantic Rainforest, São Paulo, Brazil, are described and compared with similar taxa including Entoloma pruinatocutis, Inopilus entolomoides and E. tucuchense. After a morphological study of the existing holotypes two new combinations (viz. Calliderma pruinatocutis and C. tucuchense) are proposed. I. entolomoides is considered a synonym of C. pruinatocutis. The two new species are described, with illustrations and SEM photographs of basidiospores and pileipellis structure, including most of the holotypes examined. A key for the species of Calliderma occurring in Brazil is provided.
描述了在巴西圣保罗的大西洋雨林碎片中收集到的 Calliderma 的两个新物种，C. fibulatum 和 C. rimosum，并将它们与包括 Entoloma pruinatocutis、Inopilus entolomoides 和 E. tucuchense 在内的相似分类群进行了比较。在对现有的模式标本进行形态学研究后，提出了两个新的组合（即 Calliderma pruinatocutis 和 C. tucuchense）。I. entolomoides 被认为是 C. pruinatocutis 的同义词。描述了这两个新物种，包括插图和 basidiospores 和 pileipellis 结构的 SEM 照片，其中包括检查的大部分模式标本。提供了巴西出现的 Calliderma 物种的关键。
