Abstract

Relationships among East Asian, North American and European Laetiporus sulphureus s. lat., a cosmopolitan brown rot species complex, were assessed with phylogenetic analyses and incompatibility tests. Three East Asian taxa, Laetiporus cremeiporus sp. nov., Laetiporus montanus and Laetiporus versisporus, are described and illustrated as well as compared with related taxa from Southeast Asia, North America and Europe. Phylogenetic analyses showed that L. cremeiporus and L. versisporus are clearly distinct species among Laetiporus taxa. The three conifer inhabiting species, Laetiporus conifericola, Laetiporus huroniensis and L. montanus, are closely related to each other. The European population of L. montanus exhibits two sequence variants of the EF1α: one is the same as observed in L. sulphureus in Europe and the other is that observed in East Asian population of L. montanus. A key to the known species of Laetiporus in the northern hemisphere is provided.

东亚的担子菌属(担子菌科，多孢子目)

东亚、北美和欧洲硫斑蝶的亲缘关系。采用系统发育分析和不亲和性试验对一世界性褐腐病种复合体进行了评价。本文描述了东亚的三个分类群，即cremeiporus sp. nov.、Laetiporus montanus和Laetiporus versisporus，并与东南亚、北美和欧洲的相关分类群进行了比较。系统发育分析表明，cremeiporus和versisporus在李氏菌类群中是明显不同的种。三种针叶树栖种松柏Laetiporus conifericola、胡氏Laetiporus huroniensis和montanus之间亲缘关系密切。L. montanus欧洲种群的EF1α序列有两个变异，一个与欧洲的L. sulphureus相同，另一个与东亚的L. montanus相同。提供了北半球已知的雷氏菌种类的钥匙。
