MycoBank number: MB 7005; Index Fungorum number: IF 7005; Facesoffungi number: FoF 09021 – 3 morphological species (Species Fungorum 2020), molecular data unavailable.
Type species: Acarella costaricensis Syd., Annls mycol. 25(1/2): 123 (1927).
Notes: Acarella is characterized by scattered, small, completely superficial pycnidia, with a thin peridium, and ellipsoid to cylindrical conidia. The sexual morph of Acarella is undetermined. Perizomella was synonymised under Acarella based on the host relationship and morphological characters (Pem et al. 2019c). Acarella is placed in Vizellaceae due to the asexual species have ovoid to ellipsoidal or rarely subglobose, brown to dark brown, with transverse hyaline band, formed on phialidic, hyaline cells lining the inner cavity of the upper wall (Hyde et al. 2013; Pem et al. 2019c), pending fresh collections and molecular data.
