摘　　要：基于形态学和分子系统学研究发现中国华东地区集毛孔菌一新种——武义集毛孔菌Coltriciawuyiensis。该新种在ITS和nLSU序列的系统发育分析中处于锈革孔菌目的集毛孔菌属中。武义集毛孔菌主要特征是担子果具中生菌柄;菌盖边缘全缘,表面新鲜时橘黄褐色至红褐色,具同心环区;孔口表面新鲜时土黄色至浅黄褐色;菌管菌丝疏松交织排列至近平行排列;拟担子偶尔具分隔;担孢子广椭圆形,大小为4.3–5.5×3.7–4.4μm。武义集毛孔菌在系统发育树上与小集毛孔菌C.minima具有亲缘关系,但后者的拟担子不分隔,且担孢子较大(6–7×4–5μmvs.4.3–5.5×3.7–4.4μm)。本研究提供了一个鉴定中国已知集毛孔菌种类的检索表。A new species,Coltricia wuyiensis,is described from eastern China on the basis of morphological examination and molecular phylogeny.Phylogenetic analysis based on the internal transcribed spacer(ITS)regions and nuclear large subunit(nLSU)ribosomal RNA gene regions indicates that the new species is nested within the genus Coltricia in the order Hymenochaetales.Coltricia wuyiensis is characterized by the centrally stipitate basidiomata with even margin,orange brown to reddish brown pileal surface with concentric zones and clay-buff to fawn pore surface when fresh,loosely interwoven to subparallel tramal hyphae,sometimes septate basidioles,and broadly ellipsoid basidiospores measuring 4.3-5.5x3.7-4.4μm.Phylogenetically it is closely related to C.minima,but the latter species has aseptate basidioles and bigger basidiospores(6-7x4-5μm vs.4.3-5.5x3.7-4.4μm).An identification key to accepted species of Coltricia in China is given.
