摘要

我们描述了 Diploschistes stereocaulorum，它是生长在北美洲西北太平洋地区 Stereocaulon 植物叶柄和茎秆上的地衣化真菌新物种。该物种较大的腹孢子、没有明显的菌柄以及 ITS 条形码位点将其与 D. muscorum 区分开来，后者曾被报道生长在 Stereocaulon 上，但其腹孢子较小，且有明显的菌柄。在系统发育重建中，该新种是 D. diacapsis 的姊妹种，但没有得到支持。

A new species of Diploschistes (Lecanoromycetes) occurring on Stereocaulon from the Pacific Northwest of North America

We describe Diploschistes stereocaulorum as a new species of lichenized fungi growing on phyllocladia and stalks of Stereocaulon in the Pacific Northwest of North America. The larger ascospores of this species, the absence of a noticeable thallus, and the ITS barcode locus distinguish it from D. muscorum, which has been reported as growing on Stereocaulon, but has smaller ascospores and a distinct thallus. In phylogenetic reconstruction, the new species is sister to D. diacapsis, albeit without support.
