| 中文摘要: |
| 作者对国产类脐菇属Omphalotus（含亮菌属Lampteromyces）标本进行了研究，报道4种，即鞭囊类脐菇O. flagelliformis、日本类脐菇O. guepiniformis、莽山类脐菇O. mangensis 和亮耳菌 Lampteromyces luminescens，其中鞭囊类脐菇为新种。作者对亮耳菌的模式标本进行了研究，发现它与日本类脐菇即使不是同一物种也是很近缘的，但由于没有亮耳菌模式产地或其附近地区的更多标本用于形态和分子系统发育的比较，故不对其进行分类处理。利用新近采自我国东北的标本，作者对日本类脐菇的显微特征进行了较为详细地研究，发现日本类脐菇、莽山类脐菇和亮耳菌都具有厚壁担孢子，厚壁担孢子的孢子壁外表在显微镜下看上去粗糙至不平滑，这可能是因为孢子壁不同区域的密度不同所致。云南桩菇Paxillus yunnanensis曾被猜测为类脐菇属的物种，作者对该种的模式标本进行了研究，发现模式标本具有巨大的褶缘囊状体，应是假白蘑属Tricholomopsis的成员。 |
| 英文摘要: |
| 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. |
