摘要

摘要南瓜属的模式种有两个变种，即绞股蓝和亚四里叶绞股蓝。在这项研究中，对这两个变种的系统发育和分类学分析表明，亚四轮叶S.var.sicetrioides值得作为一个独立于舞毒藻的物种进行处理。因此，我们将该品种提高到物种水平，称为S.subcetrarioides（Zahlbr.）Y.Y.Zhang。在系统发育上，次四边角鲨与舞毒藻的亲缘关系并不密切，与该物种的不同之处在于年轻时形成玫瑰花结的铊，后来变得有裂纹和轮廓不规则，并由许多小鳞片组成。

Squamarina subcetrarioides comb. & stat. nov. (Stereocaulaceae), a separate species from the type species of Squamarina

Abstract The type species of Squamarina has two varieties, S. gypsacea var. gypsacea and S. gypsacea var. subcetrarioides. In this study, a phylogenetic and taxonomic analysis of these two varieties shows that S. var. subcetrarioides merits treatment as a species separate from S. gypsacea. Therefore, we raise this variety to species level as S. subcetrarioides (Zahlbr.) Y. Y. Zhang. Squamarina subcetrarioides is phylogenetically not closely related to S. gypsacea and differs from that species in the thallus forming rosettes when young, later becoming cracked and irregular in outline, and consisting of numerous small squamules.

期刊介绍： The Lichenologist is the premier scientific journal devoted exclusively to the study of lichens worldwide. As the leading forum for the dissemination of new concepts and topical reviews, The Lichenologist reaches more scientists concerned with the study of lichens and lichen symbionts than any other single journal. All aspects of lichenology are considered including systematics and phylogenetics; molecular biology; ultrastructure, anatomy and morphology; secondary chemistry, effects of pollutants and use as bioindicators; biogeography. In addition to standard length research papers, the journal also publishes Short Communications and Book Reviews. A monthly issue may occasionally be devoted to papers deriving from a symposium.
