摘要
利用形态学和分子数据修订了Acarospora molybdina的命名法和分类法。提出了新的组合 Myriospora molybdina，Acarospora hysgina 被认为是一个独特的种，而 A. brunneola 则与 A. hysgina 降为同义。molybdina 是一个北极种，在斯堪的纳维亚半岛仅分布于挪威最北部。格陵兰岛、俄罗斯、斯瓦尔巴特群岛和美国（阿拉斯加）也有分布。Acarospora hysgina 是分布在瑞典和挪威西海岸的一个物种的正确名称，以前被认为属于 A. molybdina。加拿大（新不伦瑞克）、格陵兰岛和美国（缅因州）也有地方报道。以下名称已进行了标本分型：Acarospora brunneola、A. molybdina var. confusa、Lecanora ereutica β microcyclos、Parmelia ereutica、P. hysgina 和 P. molybdina。
Myriospora molybdina comb. nov. and the identity of Acarospora hysgina
The nomenclature and taxonomy of Acarospora molybdina is revised using morphological and molecular data. The new combination Myriospora molybdina is proposed and Acarospora hysgina is recognized as a distinct species while A. brunneola is reduced to synonymy with A. hysgina. In its new circumscription M. molybdina is an arctic species, in Scandinavia only occurring in northernmost Norway. Further localities are reported from Greenland, Russia, Svalbard and the USA (Alaska). Acarospora hysgina is the correct name for a species distributed along the west coast of Sweden and Norway, formerly thought to belong to A. molybdina. Localities are also reported from Canada (New Brunswick), Greenland and the USA (Maine). The following names are lectotypified: Acarospora brunneola, A.molybdina var. confusa, Lecanoraereutica β microcyclos, Parmelia ereutica, P. hysgina and P. molybdina.
