云南省的糙孢孔菌属(糙孢孔目,担子菌门)一新种OA
A new species of Trechispora(Trechisporales,Basidiomycota)from Yunnan Province,Southwest China
木生真菌在森林生态系统中作为分解者发挥着关键作用.本研究基于形态特征与分子证据从云南发现一种新的木生真菌——景谷糙孢孔菌Trechispora jingguensis.该新种的主要特征为:担子果平伏,子实层表面具小短齿,新鲜时呈白色至淡米色,干燥后转为浅米色,菌丝系统一体系,生殖菌丝具锁状联合,担孢子椭圆形,具刺.通过 ITS 和 nLSU 分子片段测序,结合最大似然法、最大简约法与贝叶斯推断法,对研究标本进行了系统发育分析.分子系统学研究结果表明:景谷糙孢孔菌T.jingguensis聚类至糙孢孔菌属,并与晶体糙孢孔菌T.crystallina构成姊妹群.本文提供了该新种的详细形态描述、显微图片及系统发育分析结果,以支持其分类学地位.
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.
