Apiosphaeria Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 118: 1218 (1909)
Index Fungorum number: IF7566; 1 species with sequence data.
Type species – Apiosphaeria guaranitica (Speg.) Höhn.
Notes – Apiosphaeria has been traditionally placed in Phyllachoraceae, based exclusively on morphological studies, without supporting molecular evidence. Guterres et al. (2018) provided molecular data for the link between sexual and asexual states of the fungus and elucidate the phylogeny of A. guaranitica. Their results indicate a natural placement of Apiosphaeria within Diaporthaceae, where it represents an ancient lineage of the crown group of Diaporthaceae.
