中国奥氏衣属地衣三个新记录种
Three new records of the lichen genus Oxneriaria from China
摘要
Abstract
In order to explore the diversity of Oxneriaaria in Xinjiang,morphological,anatomical,chemical analyse,and combined with phylogenetic analysis based on rDNA-ITS sequences,are used to conduct a detailed taxonomic study on Oxneriaria specimens collected from Xingjiang,China.The results are as follows:(1)A total of three Oxneriaria lichens belong to the Chinese new record species,namely O.supertegens(Arnold)S.Y.Kondr.& Lökös,O.verruculosa(Kremp.)S.Y.Kondr.& Lökös,and O.permutata(Zahlbr.)S.Y.Kondr.& Lökös.Detailed descriptions and anatomical diagrams of the internal and external morphological structures of these three new record species are provided.In addition,similar species are compared and discussed.(2)O.supertegens is characterized by the dark gray to gray-brown with a slightly purple tinge,with black prothallus,apothecium dictyoplast,lecanorine,hymenium 89.5-135.0 μm,8-spored asci,ellipsoid ascospores(16.0-25.5)μm ×(12.0-16.5)μm;O.verruculosa is characterized by a wart-like thallus and like altar-shaped apothecium,apothecium aspiciloid,hymenium 70.5-95.0 μm,8-spored asci,ellipsoid ascospores(12.0-17.5)μm ×(7.5-13.5)μm,and contains stictic acid;O.permutata is characterized by the uneven and rough surface of thallus,apothecium aspiciloid,hymenium 100-115 μm,8-spored asci,ellipsoid ascospores(15.0-22.0)μm ×(9.0-12.5)μm.The research results have increased the number of Oxneriaria species in China from 3 to 6,accounting for 32％of the total global species,enriching the basic data of Oxneriaria lichens in China.关键词
