摘要
报道了采自我国安徽省金寨县天堂寨的木霉属Trichoderma两个新种。新种天堂寨木霉T.tiantangzhaiense位于Hypocreanum分支,子座黄褐色至淡褐色,平垫状至盘状,子囊孢子相对较小;新种余氏木霉T.yui与沃格玛木霉T.voglmayrii亲缘关系较近,具有橙褐色至金棕色子座,褐色至红褐色孔口区和绿色分生孢子。本文提供了这两种木霉宏观和微观特征的详细描述及图示,并探讨了其分类地位。
Collections of Trichoderma species having hyaline ascospores from Tiantangzhai, Jinzhai, Anhui Province were examined. Using combined analyses of morphological data, culture characters and molecular phylogeny, two new species are recognized and described. Trichoderma tiantangzhaiense, as a member of the Hypocreanum clade, is characterized by flat pulvinate to discoid, yellow to light brown stromata and relative or golden brown stromata with well-defined brownish to reddis ly h- small part-ascospores. Trichoderma yui has brownish orange brown ostiolar dots and green conidia, and is closely related to but distinct from T. voglmayrii. The distinctions between the new species and their close relatives are discussed, and their phylogenetic positions are explored
