摘　　要：本文根据形态学特征和分子系统学分析报道了产于中国西南山地温带森林的棒瑚菌属新种2个。第一个新种金黄棒瑚菌Clavariadelphus aurantiacus具有亮橙黄色的子实体和不育的子实体顶部,第二个新种纤细棒瑚菌C.tenuis具有细长的子实体并且菌丝不具锁状联合。为两个新种提供了详细的描述、绘制了黑白线条图、拍摄了彩色照片,并且与类似的物种进行了比较。运用核糖体转录区间序列分析了棒瑚菌属的系统发育关系。提供了中国已知棒瑚菌的检索表。Two new club fungi of Clavariadelphus(Clavariadelphaceae,Gomphales,Basidiomycota)from alpine temperate forests in southwestern China are substantiated based on morphological evidence and molecular phylogenetic analyses.Clavariadelphus aurantiacus is characterized by its turbinate,bright orange-yellow basidiomata with a sterile apex.Clavariadelphus tenuis has slender basidiomata and clampless hyphae.The two species are described in detail and illustrated with line drawings and photographs.Comparison between the new species and similar species is made.Phylogenetic relationships in Clavariadelphus are analyzed based on internal transcribed spacer r DNA sequences.A key to known Clavariadelphus species in China is provided.
