Two new species of Trichoderma with hyaline ascospores from Anhui of China
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 relatively small part-ascospores.Trichoderma yui has brownish orange or golden brown stromata with well-defined brownish to reddish-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.
