Abstract

Abstract As part of a revision of the genus Acanthothecis s. lat. (Graphidaceae) in Brazil, an updated world key to the known species of the genus is presented. From Brazil, the following ten new species are described: A. latispora, with single-spored asci, large, muriform ascospores, and norstictic and stictic acids; A. megalospora, with single-spored asci, very large, transversely septate ascospores, and norstictic and protocetraric acids; A. multiseptata, with 8-spored asci, medium-sized and narrow, transversely multiseptate ascospores, and lacking secondary substances except terpenoids; A. norstictica, with 1–2-spored asci, large, muriform ascospores, and norstictic acid; A. oryzoides, with 8-spored asci, medium-sized, transversely septate ascospores, and norstictic acid; A. rimosa, with 2-spored asci, small to medium-sized, muriform ascospores, and stictic acid; A. roseola, with 1–2-spored asci, large, muriform ascospores, and norstictic, stictic and subnorstictic acids; A. saxicola, with 8-spored asci, small, 3-septate ascospores, and norstictic acid; A. subfarinosa, with 8-spored asci, small, 6–8-septate ascospores, and norstictic acid; and A. submuriformis, with 8-spored asci, small, submuriform ascospores, and lichexanthone. In addition, three further species are formally validated, namely A. bicellulata, A. farinosa and A. subabaphoides, and the new combination A. bicellularis is proposed, based on Acanthotrema bicellularis.

棘棘属世界检索表的更新。(子囊菌纲:石墨科)，附10新种

摘要作为对巴西棘皮猴属（Graphidaceae）进行修订的一部分，提出了该属已知物种的最新世界索引。在巴西，描述了以下十个新种：宽孢A.latispora，具有单孢腹水，大的鼠形子囊孢子，以及北欧和北欧酸；A.大孢子虫，具单孢腹水，非常大，横向有隔膜的子囊孢子，以及北向和原四烯酸；A.多裂，具8孢子的子囊，中等和狭窄，横向多裂的子囊孢子，除萜类外缺乏次生物质；A.norstictica，具有1-2孔的腹水、大的、鼠形的子囊孢子和norsticic酸；A.oryzoides，具有8孢子的子囊，中等大小，横向有隔膜的子囊孢子，和北欧酸；A.rimosa，具2孔腹水，小到中等大小，鼠形子囊孢子，和Stitic酸；A.roseola，具有1-2孔的腹水，大的、鼠形的子囊孢子，以及北向、北向和亚北向酸；A.saxicola，具有8个孢子的子囊，小的3个正庚子囊孢子，和北欧酸；A.亚科，具8孢子的子囊，小的，6-8间隔的子囊孢子，和北欧酸；和A.submuriformis，具有8个孢子的asci、小的submuriform子囊孢子和地衣。此外，还正式验证了另外三个物种，即A.bicellularata、A.farinosa和A.subabaphoides，并在Acanthotrema bicellularis的基础上提出了新的组合A.bicellular。

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.
