摘要

Based on an exhaustive sampling of all known Lepidostromatales, a lineage of clavarioid lichen-forming basidiomycetes, we assess (i) the phylogenetic affinities of the six Chinese species currently accommodated in Multiclavula (Cantharellales) based on inferences from the 18S and 28S subunits of the nuclear ribosomal DNA repeat and (ii) the phylogenetic structure among Chinese populations of Lepidostromatales, based on the nuc rDNA ITS1-5.8S-ITS2 (internal transcribed spacer [ITS]) regions. Multiclavula fossicola and M. sinensis belong to the Lepidostromatales and are transferred to Sulzbacheromyces. Chinese reports of M. clara and M. vernalis belong to species of Lepidostromatales, and specimens identified as M. mucida belong to the nonlichenized genus Clavaria. Hence, evidence of Multiclavula occurring in China is lacking. Similarly, L. calocerum is excluded from the Chinese flora. The recently described L. asianum should be regarded as conspecific with S. sinensis. Three new species of Sulzbacheromyces are described: S. bicolor and S. yunnanensis from China and S. miomboensis from the Democratic Republic of Congo. Consequently, Sulzbacheromyces is new to Asia and Africa. A worldwide key to the species of Lepidostromatales is provided.

Sinensis属于鳞片孢子瘤,并转移到Sulzbacheromyces。中国克拉拉和M.Vernalis的中国报告属于鳞翅粒瘤的种类,并确定为M. mucida的标本属于非粘性属克拉维亚。因此,缺乏在中国发生的多套管的证据。同样,L. Calocerum被排除在中国植物群中。最近描述的L. Asianum应该被视为与S.Inensis的熟食。从刚果民主共和国的中国和S.Miomboonensis中描述了三种新的Sulzbacheromyces物种,来自中国和S. yunnanensis。因此,Sulzbacheromyces对亚洲和非洲是新的。提供了Lepidostromatales种类的全球关键。
