新疆原类梅属地衣的初步研究

Preliminary Study on the Lichen Genus Protoparmeliopsis in Xinjiang,China

该文对新疆原类梅属(Protoparmeliopsis M.Choisy)地衣进行了分类学研究。采用形态解剖学、化学及分子生物学方法,鉴定了采样区原类梅属地衣的4个种:凹盘原类梅[Protoparmeliopsis laatokkaensis(Räsänen)Moberg&R.Sant],戛氏原类梅[P.garovaglii(Körb.)Arup,Zhao Xin&Lumbsch]、石墙原类梅[P.muralis(Schreb.)M.Choisy]和盾原类梅[P.peltata(Ramond)Arup,Zhao Xin&Lumbsch],其中凹盘原类梅(P.laatokkaensis)为中国新记录种。该种最主要的辨别特征是具沉陷入地衣体生长的子囊盘和很明显的黑色下地衣体。对以上4种地衣的形态解剖、化学特征和生境进行了描述,同时提供了分种检索表和相关彩色图片。

In this paper,a taxonomic study on the Lichen genus Protoparmeliopsis M.Choisy from Xinjiang were conducted.Four species of Protoparmeliopsis,P.laatokkaensis(Räsänen)Moberg&R.Sant,P.garovaglii(Körb.)Arup,Zhao Xin&Lumbsch,P.muralis(Schreb.)M.Choisy,P.peltata(Ramond)Arup,Zhao Xin&Lumbsch,collected in sampling area were identified by morphological,anatomical,chemical and molecular biological methods.Among them,Protoparmeliopsis laatokkaensis is new to China.P.laatokkaensis distinguished by having an areolate to weakly lobate thallus,semi-immersed apothecia and with visible black prothallus.The morphological,anatomical,chemical and ecological descriptions of species are given.Photos of Protoparmeliopsis species occurred in study area of Xinjiang and key are also presented.
