Abstract

Abstract. The new species Roccella ramitumidula is described from a tropical dry forest in the Pacific Coast of Mexico. The new species is characterized by fertile thalli, saxicolous habit, irregularly swollen branches and erythrin and lecanoric acid as lichen products. It differs from R. decipiens by its narrower and longer ascospores, irregularly swollen branches, uneven surface, and smaller branches. Sequences of the genetic markers ITS, nuLSU and RPB2 from the new species were added to a phylogenetic tree based on four genetic markers that included all the Roccella species known for the Americas. The biogeography and ecology of the species is discussed. We reported R. gracilis for the first time for the state of Jalisco, Mexico.

墨西哥热带干燥森林的一新种——罗ccella ramitumidula

摘要新物种罗ccella ramitumidula来自墨西哥太平洋海岸的热带干燥森林。该新种的特点是:菌体肥沃，结砂习性，枝干不规则膨大，地衣产物为赤藓苷和lecanoric酸。它的子囊孢子较窄而长，分枝不规则膨大，表面不平整，分枝较小，与裂皮鼠不同。来自新物种的遗传标记ITS, nuLSU和RPB2序列被添加到基于四个遗传标记的系统发育树中，该遗传标记包含了美洲已知的所有罗ccella物种。讨论了该物种的生物地理学和生态学。本文首次在墨西哥哈利斯科州报道了该病菌。

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.
