Abstract

Abstract. Sticta is a subcosmopolitan, predominantly epiphytic lichenizing fungal genus characteristic of open sites in humid late-successional ecosystems. Recent molecular analysis has shown that the laminally isidiate species S. fuliginosa, long assumed to be well delimited, encompasses >20 phylospecies which, taken together, constitute the S. fuliginosa morphodeme. Here we elucidate the northwestern North American members of this morphodeme based on a rich sampling from throughout the Pacific Northwest regions of the U.S.A. and Canada: Alaska, British Columbia, California, Oregon and Washington. Our results support recognition of five species, three of which – S. arenosella sp. nov., S. fasciculata sp. nov. and S. torii – appear to be endemic. Of the remainder, S. globulifuliginosa was described from Colombia, while S. gretae sp. nov. occurs also in the Canary Islands and China. Two of our new species – S. fasciculata and S. gretae comprise a new phylogenetic lineage and is referred to as the S. gretae clade. New taxonomically informative thallus characters are introduced and a key to the genus Sticta in northwest North America is provided.

清除北美西北部的fuliginosa Morphodeme Sticta

摘要Sticta是一个亚群落，主要为附生地衣真菌属，在潮湿的演替后期生态系统中具有开放场所的特征。最近的分子分析表明，长期以来被认为是界限明确的层间介体物种黄颡鱼包括20多个门，这些门合在一起构成了黄颡虫形态结构。在这里，我们根据从美国和加拿大的整个太平洋西北地区（阿拉斯加、不列颠哥伦比亚省、加利福尼亚州、俄勒冈州和华盛顿州）进行的丰富采样，阐明了该地貌区的北美洲西北部成员。我们的研究结果支持了对五个物种的识别，其中三个物种——沙氏菌S.arenosella sp.nov.、束状菌S.cyculata sp.nov..和托里氏菌S.torii——似乎是地方病。在其余的物种中，球孢S.glombifuliginosa来自哥伦比亚，而S.gretae sp.nov.也出现在加那利群岛和中国。我们的两个新种——束状S.chuculata和灰蝶S.gretae组成了一个新的系统发育谱系，被称为灰蝶分支。介绍了新的分类信息铊特征，并提供了北美洲西北部Sticta属的一个关键。

期刊介绍： The Bryologist is an international journal devoted to all aspects of bryology and lichenology, and we welcome reviews, research papers and short communications from all members of American Bryological and Lichenological Society (ABLS). We also publish lists of current literature, book reviews and news items about members and event. All back issues of the journal are maintained electronically. The first issue of The Bryologist was published in 1898, with the formation of the Society. Author instructions are available from the journal website and the manuscript submission site, each of which is listed at the ABLS.org website. All submissions to the journal are subject to at least two peer reviews, and both the reviews and the identities of reviewers are treated confidentially. Reviewers are asked to acknowledge possible conflicts of interest and to provide strictly objective assessments of the suitability and scholarly merit of the submissions under review.
