中文摘要：

在云南紫溪山自然保护区的木材腐朽菌研究中发现87种多孔菌,其中多数是云南首次报道,给出了每种的寄主和生长基质。锥沃菲卧孔菌Wolfiporia castanopsis为一新种,其特点为子实体平伏,孔口表面奶油色至浅灰色,担孢子椭圆形至广椭圆形,且生长在元江锥腐朽木上;该种与茯苓沃菲卧孔菌Wolfiporia cocos具有相似的孔口,但后者的担孢子为圆柱形,且通常生长在菌核上。

英文摘要：

Eighty-seven polypore species were identified from materials collected in the Zixishan Nature Reserve,Yunnan Province,China.A checklist of these species is supplied and the host tree or substrate of each species is listed.Most of the species are reported for the first time in Yunnan Province.Wolfiporia castanopsis Y.C.Dai（Polyporales,Basidiomycota） is described as new.It is characterized by resupinate basidiocarps,cream to ash-grey pore surface,ellipsoid to broadly ellipsoid spores and by growth on wood of Castanopsis.It is similar to Wolfiporia cocos which,however,has cylindrical basidiospores（8-11＊3-4μm） and its basidiocarp is normally on sclerotia.
