Acarella
Wijayawardene et al. (2012) listed Acarella in Asterinaceae. Pem et al. (2019b) transferred Acarella to Vizellaceae based on the ovoid to ellipsoidal or rarely subglobose, brown to dark brown ascospores, with a transverse hyaline band, formed on phialidic, hyaline cells lining the inner cavity of the upper wall (D. Pem).
