中文摘要：

在四川青城山风景区发现木材腐朽菌60种,给出了每个木材腐朽菌的寄主和生长基质。拟黄薄孔菌Antrodia subxantha为一新种,其特点为子实体平伏,孔口表面黄色,担孢子圆柱形至窄椭圆形（3-4×1.6-2.1μm）,菌髓主要由生殖菌丝组成;该种与黄薄孔菌Antrodiaxantha具有相似的孔口表面,但后者的担孢子为腊肠形（4-5×1.2-1.5μm）,且其菌髓主要有骨架菌丝组成。

英文摘要：

Sixty wood-decaying fungi were identified from materials collected from four field trips in the Qingcheng Mts.,Sichuan Province,southwestern 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 the studied area.Antrodia subxantha Y.C.Dai X.S.He（Polyporales,Basidiomycota） is described as new.It is characterized by resupinate basidiocarps,yellow pore surface,generative hyphae dominant in tube trama,cylindrical to oblong-ellipsoid basidiospores（3-4×1.6-2.1μm）.It is very similar to Antrodia xantha in macromorphology,but the latter has allantoid basidiospores（4-5×1.2-1.5μm）,and its trama is dominated by skeletal hyphae.
