中国西南地区脊革菌属(担子菌门)两个新种
Two new species of Lopharia(Basidiomycota)from southwest China
摘要
Abstract
Wood-decaying fungi play crucial roles as decomposers in forest ecosystems.In this study,two new Lopharia species from Yunnan Province in southwest China,Lopharia minispora and Lopharia punctata,are described and illustrated based on the morphological and molecular evidence.L.minispora is characterized by its slightly brown and cracked basidiomata when dry,a monomitic hyphal system with clamp connections,and oblong-ellipsoid basidiospores measuring 5.5-6.7×2.7-3.3 µm;L.punctata is characterized by its membranous,white to cream basidiomata,a monomitic hyphal system with simple-septa on generative hyphae and subglobose to globose basidiospores measuring 9.5-12×7.5-10.1 µm.Sequences of ITS and nLSU rDNA markers of the studied samples were employed,and phylogenetic analyses were performed with maximum likelihood,maximum parsimony and Bayesian inference methods,ensuring the reliability of our findings.The dataset analyses showed that the two new species clustered into the genus Lopharia,in which L.minispora was sister of Lopharia erubescens;L.punctata grouped with the lineage of Lopharia ayresii and Lopharia resupinata.关键词
