The genus Omphalotus (Omphalotaceae) in China * YANG Zhu-Liang FENG Bang Key Laboratory of Biodiversity and Biogeography, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming, Yunnan 650201, China Abstract: Specimens of Omphalotus (including Lampteromyces) in China were studied and four species, viz. O. flagelliformis sp. nov., O. guepiniformis, O. mangensis and Lampteromyces luminescens, were reported. Based on holotype observation, it is found that L. luminescens is very close to O. guepiniformis (O. japonicus) if they are not conspecific. Because no additional materials of L. luminescens from the type locality or its adjacent areas are available for morphological or molecular phylogenetic comparison, we keep L. luminescens as distinct for the time being. The transfer of L. luminescens to Omphalotus requires further investigation. Microscopic characters of O. guepiniformis from newly collected materials in northeastern China showed that crassospores were as common in O. guepiniformis as in O. mangensis and L . luminescens. Surfaces of crassospores are finely rough to uneven under microscope, which is probably due to the non-uniform density of the spore wall. Paxillus yunnanensis was also considered as a species of Omphalotus. Reexamination of the holotype of P. yunnanensis indicated, however, that it is likely congeneric with Tricholomopsis, with prominently large cheilocystidia.
