Notes – The genus comprises insect parasitic fungi. The sexual morphs are hypocrella-like (Mongkolsamrit et al. 2009). Some species may control insect pests (Meekes et al. 2002, Wei et al. 2016). Rossman et al. (2016) recommended protecting Hypocrella over Aschersonia although Aschersonia is an earlier name. However, the name Aschersonia was wildly used and many molecular data were provided to the species of this genus. To respect the earlier name Aschersonia, we suggest preserving Aschersonia over Hypocrella. Species infect scale insect and whiteflies and produce bright, pulvinate or discoid stromata or conidiomata, superficial or embedded perithecia, cylindrical asci, non-disarticulating ascospores, and fusiform conidia with acute ends (Chaverri et al. 2008). In this entry we illustrate Aschersonia insperata. 

Type species: Aschersonia tahitensis Mont. [as ‘Aschersonia taitensis’], (1848).

Other accepted species: Species Fungorum – search Aschersonia.
