Knudsen K and Kocourková J. 2017. Acarospora toensbergii (Acarosporaceae), a new species from Alaska, U.S.A.. Opuscula Philolichenum. 16:317-321
Acarospora toensbergii is described from Alaska in North America. The new species grows on siliceous rock and is easily recognized by its dispersed, solitary apothecia with a thick brown thalline margin, its amyloid hymenium and subhymenium, its lack of secondary metabolites, and its large mature ascospores that often measure up to 7 × 3 μm. Reports of Acarospora gallica and A. variegata from North America (New Mexico) are misidentifications of Acarospora janae. Acarospora canadensis is removed from synonymy with Acarospora glaucocarpa
