中国多孔菌一新记录种——韦氏小针层孔菌

摘要

根据中国的标本材料对中国多孔菌一新记录种--韦氏小针层孔菌[Phellinidium weirii(Murrill)Y.C.Dai]进行了详细描述,并讨论了该种与其相似种硫色小针层孔菌的区别:该种担子果多年生,管孔较小(5～7vs.4～5 per mm),管口全缘,担孢子不嗜蓝,只生长在柏树上.该种分布于青海省祁连山地区,生长在祁连圆柏上,造成祁连圆柏根部白色腐朽.%A new polypore, Phellinidium weirii (Murrill) Y. C. Dai, is reported from Northwest China. An illustrated description of the fungus is given from Chinese collection. Phellinidium weirii is closely related to P. sulphurascens (Pilát) Y. C. Dai, but differs by its perennial basidiocarps, smaller pores(5 ～ 7 vs. 4 ～ 5 per mm), entire tube mouths, acyanophilous basidiospores, and by living on species of the Cupressaceae. Phellinidium weirii lives on Sabina przewalskii,and causes laminated root rot of the trees.
