A new genus, Neoaleurodiscus, is proposed as a segregate from Aleurodiscus (Basidiomycota), and the new species, Neoaleurodiscus fujii, is described. It was collected at the timberline of Mount Fuji, Japan. Specimens were found on trunks of Rhododendron sp. Morphological study and phylogenetic analysis based on sequence data derived from LSU nrDNA indicated that Neoaleurodiscus is separate from other segregate genera from Aleurodiscus s.l. Neoaleurodiscus is characterized by having a disciform basidiocarp; microscopically it has moniliform gloeocystidia, absence of acanthophyses, nodose-septate hyphae, hyphidia, and basidiospores, which are amyloid, smooth and +/- thick-walled. Among genera studied Acanthobasidium and Aleurodiscus (s.s.) are most closely related to Neoaleurodiscus, but these genera have warted or spiny basidiospores. Two new combinations, Acanthobasidium penicillatum and Neoaleurodiscus monilifer, are proposed.
一个新的属，新球腔菌属，被提议作为从球腔菌属（担子菌门）中分离出来的一个分类群，并且描述了一个新物种，富士新球腔菌。它是在日本富士山的林线处采集的。在杜鹃属植物的树干上发现了标本。基于 LSU nrDNA 序列数据的形态学研究和系统发育分析表明，新球腔菌与其他从球腔菌属（广义）中分离出来的分类群不同。新球腔菌的特征是具有盘状的担子果；微观上，它具有单生的拟珊瑚状胶质细胞，没有刺毛，节结状分隔的菌丝、刚毛和担子孢子，这些孢子是淀粉质的，光滑的，并且具有 +/-厚壁。在所研究的属中，刺球腔菌属和球腔菌属（狭义）与新球腔菌最接近，但这些属的担子孢子具有疣状或具刺状。提出了两个新的组合，即 penicillatum 刺球腔菌和 monilifer 新球腔菌。
