Apiosporina Höhn., Sber. Akad. Wiss. Wien, Math.- naturw. Kl., Abt. 1 119: 439 (1910).

MycoBank number: MB 266; Index Fungorum number: IF 266; Facesoffungi number: FoF 06354; – 3 morphological species (Species Fungorum 2020), 2 species with molecular data.

Type species: Apiosporina collinsii (Schwein.) Höhn.

Notes: Apiosporina species are characterized by erumpent, subglobose, black ascomata, 8-spored bitunicate, subcylindrical or broadly clavate asci and hyaline to pale brown, clavate apiospores (Zhang et al. 2011). The asexual morph of A. collinsii was reported as Cladosporium sp. (Sivanesan 1984) and it was assigned as Fusicladium sensu lato by Braun et al. (2003). Dibotryon had been treated as a synonym of Apiosporina (von Arx and Müller 1975; Crous et al. 2007b). Although the black knots on branches of Prunis cultis formed by Dibotryon morbosum can readily be distinguished from the black spots on leaves formed by Apiosporina, their congeneric relationship was confirmed by molecular data (Winton et al. 2007). Sequence data are available for Apiosporina collinsii and Apiosporina morbosa.
