摘要

Buellia numerosa and B. subnumerosa are described as new from Japan. These two corticolous species share common morphological characters: whitish, smooth to rimose thallus; adnate apothecia; flat, epruinose disc; dispersa-type proper exciple; numerous ascospores per ascus; and Buellia-type ascospores. In addition, they share chemical characters: presence of fumarprotocetraric acid and atranorin. They are clearly distinguishable from previously-described Buellia species based on their ascospore numbers and metabolites, and from each other by the number of ascospores per ascus and characters of the asci. Buellia numerosa has 20-64 ascospores per ascus while B. subnumerosa produces 8-36. Also, brown overmature asci are always found in B. subnumerosa, but not in B. numerosa. A phylogenetic analysis based on the ITS region confirmed that they should be recognized as two different species.

Subnumerosa被描述为来自日本的新型。 这两种皮质物种分享常见的形态特征:发白,光滑为rimose thallus; adnate apothecia; 平,乙烯酶圆盘; Dispersa型适当的激光; 众多囊孢孢子; 和Buellia型囊孢子。 此外,它们分享化学特征:存在富马丙酸和阿氨酸。 它们在基于先前描述的Buellia物种,基于其Ascospore号和代谢物和代谢物,以及通过ASCI的囊孢子的数量和ASCI的特征,它们是明显的。 Buellia Numerosa每亚ascus有20-64个囊孢子,而B. subnumerosa产生8-36。 此外,棕色过度成熟的ASCI始终在B. subnumerosa中找到,但不是在B. Numerosa。 基于其区域的系统发育分析证实,它们应该被认为是两种不同的物种。
