云南省的糙孢孔菌属(糙孢孔目,担子菌门)一新种
A new species of Trechispora(Trechisporales,Basidiomycota)from Yunnan Province,Southwest China
摘要
Abstract
Wood-inhabiting fungi play crucial roles as decomposers in forest ecosystems.In this study,a new wood-inhabiting fungus,Trechispora jingguensis,is proposed based on a combination of morphological features and molecular evidence.Trechispora jingguensis is characterized by resupinate basidiomata with grandinioid,white to slightly buff when fresh,turning slightly buff upon drying,a monomitic hyphal system,generative hyphae with clamp connections,and ellipsoid and aculeate basidiospores.Phylogenetic analysis was based on ITS and nLSU sequences,in combination with ML,MP,and BI methods.The results showed that the new species T.jingguensis was sister to T.crystallina.A full description,illustrations and phylogenetic analysis results of the new species are provided.关键词
