Type species – Leptosphaerulina australis McAlpine, Fungus Diseases of stone-fruit trees in Australia: 103. 1902.

Notes – Leptosphaerulina was introduced to accommodate the type species L. australis (McAlpine 1902). It was first accommodated in Pleosporaceae (Inderbitzin et al. 2000, Kodsueb et al. 2006) but Kodsueb et al. (2006) assigned this genus under Didymellaceae. Only the sexual morph has been observed. Leptosphaerulina is distinct from Macroventuria and Didymella even though they have hyaline ascospores. Leptosphaerulina produces large, longitudinally and transversally septate ascospores (Aveskamp et al. 2010). There are ten species assigned to this genus (Tennakoon et al. 2019) while there are 62 associated records in Index Fungorum (2020) and 69 records in MycoBank (2020).
