Memnoniella is one of the diverse genera in Stachybotryaceae and, 24 epithets listed in Index Fungorum (2022). Memnoniella members are characterized by having macronematous, mononematous, unbranched conidiophores, phialidic conidiogenous cells with conspicuous collarettes, and unicellular, aseptate, smooth to verrucose conidia arranged in dry chains or slimy masses (Lombard et al. 2016, Zheng et al. 2019). This study followed Tennakoon et al. (2021) as the latest treatment for this genus.

Type species: Memnoniella aterrima Höhn., Centbl. Bakt. ParasitKde, Abt. II 60: 16 (1923) [1924].

Other accepted species: Species Fungorum – search Memnoniella.
