MycoBank number: MB 7191; Index Fungorum number: IF 7191; Facesoffungi number: FoF 01427; 12 morphological species (botryosphaeriales.org 2020), 10 species with molecular data.

Type species: Aplosporella chlorostroma Speg.

Notes: Aplosporella was introduced by Spegazzini (1880). This genus has frequently been incorrectly referred to as “Haplosporella” (Tilak and Rao 1964; Petrak and Sydow 1927; Tai 1979; Wei 1979). About 340 epithets for Aplosporella are listed in Index Fungorum (July 2019). This genus is characterised by multiloculate pycnidia, brown, aseptate, spinulose conidia, hyaline, aseptate spermatia and fusiform paraphyses (Du et al. 2017). Its sexual morph is not common (Ekanayaka et al. 2016). Slippers et al. (2013) indicated that Aplosporella should be separate from Botryosphaeriaceae as a distinct family, which they named Aplosporellaceae, and confirmed that Aplosporella is well-resolved with species described from living culture. They also found a close genetic relationship between the genera Aplosporella and Bagnisiella and considered that Bagnisiella represents the sexual morph and should be reduced to synonymy with Aplosporella (Schoch et al. 2009a; Slippers et al. 2013). Ekanayaka et al. (2016) introduced a new species Aplosporella thailandica from Thailand with morphology corresponding to Bagnisiella. Phillips et al. (2019) formally placed Bagnisiella as a synonym of Aplosporella. The most recent phylogenetic tree of species in Aplosporella is provided by Hyde et al. (2020a).
