Abstract

A phylogenetic analysis recovered Acarospora oreophila in the monophyletic Trimmatothelopsis clade and a new combination was made. Trimmatothelopsis oreophila is closely related to T. terricola. Acarospora benedarensis and A. sphaerosperma are transferred to Trimmatothelopsis based on morphological and anatomical analyses. Globose apothecia with the disc usually less 0.5 mm in diam., a high hymenium, narrow paraphyses, and long conidia (3–6 × 1–1.5 µm) are diagnostic characters of the genus. Five species occur in North America.
