Höhnel (1919) introduced Keissleriella to accommodate K. aesculi (Höhn.) Höhn.
(≡ Pyrenochaeta aesculi Höhn.). This genus is characterized by ascomata with ostiolar necks filled with black setae, and one to multi-septate, hyaline to pale brown ascospores (Barr 1990, Liu et al. 2015, Wanasinghe et al. 2018b, Phookamsak et al. 2019). The asexual morph comprises unbranched or branched, smooth, flexuous, hyaline conidiophores, phialidic conidiogenous cells and hyaline to brown, aseptate or septate conidia (Hyde et al. 2020). Munk (1957) placed Keissleriella in Lophiostomataceae, and then von Arx & Muller (1975) included it in Pleosporaceae. Subsequently, Barr (1990) placed it in Melanommataceae, while Lumbsch & Huhndorf (2007) transferred Keissleriella in to Massarinaceae. Zhang et al. (2009) included the genus in Lentitheciaceae, and this is followed by many subsequent authors (Zhang et al. 2012, Hyde et al. 2013, Wijayawardene et al. 2014, Tanaka et al. 2015, Wanasinghe et al. 2017b, 2018b, Phookamsak et al. 2019, Hyde et al. 2020).

Type species: Keissleriella aesculi (Höhn.) Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 128(7-8): 582 (1919).

Other accepted species: Species Fungorum – search Keissleriella.
