新科Rhizoplacopsidaceae中的新属及新种Rhizoplacopsis weichingii(英文)

A new genus and species Rhizoplacopsis weichingii in a new family Rhizoplacopsidaceae (Ascomycota)

本文描述了位于新科盾叶科 Rhizoplacopsidaceae(Umbilicariales,Lecanoromycetes,Ascomycota)中的新属盾叶属 Rhizoplacopsis 和新种蔚青盾叶 Rhizoplacopsis weichingii。蔚青盾叶取名于著名中国真菌学家王云章教授之字“蔚青”,作为庆祝教授百岁生日之纪念。该新种在外形上与 Rhizoplaca 属地衣极为相似,但位于地衣体上的子囊盘却为网衣型。此外,它的子囊顶器结构非常接近于 Umbilicaria-type。基于分子数据,对 Rhizoplacopsis weichingii 及其它相关地衣进行的系统发育分析支持成立新属盾叶属 Rhizoplacopsis 和新科盾叶科 Rhizoplacopsidaceae。

A new genus and species Rhizoplacopsis weichingii in a new family Rhizoplacopsidaceae within Umbilicariales, Lecanoromycetes, Ascomycota are described in this paper. The new species is similar morphologically to species of Rhizoplaca, from which it is different by lecideine apothecia located mainly in the center of the thallus among several peltate scales. Also, its ascus apex structure belongs to the Umbilicaria-type. The phylogenetic analyses of Rhizoplacopsis weichingii and other umbilicate lichens based on the molecular data support our conclusion to describe the new family Rhizoplacopsidaceae.
