Phaeodimeriella Speg., Revta Mus. La Plata 15(2): 13 (1908).

MycoBank number: MB 3908; Index Fungorum number: IF 3908; Facesoffungi number: FoF 01927; 27 morphological species (Species Fungorum 2020), molecular data unavailable.

Type species: Phaeodimeriella parvula (Cooke) Hansf.

Notes: Phaeodimeriella was lectotypified by P. occulta (Theissen 1912). However, P. occulta was synonymized under P. parvula by Hansford (1946), therefore the current name of the type species is P. parvula. Mapook et al. (2016a) provided molecular data of P. cissampeli and P. dilleniae. In their analyses, the clade of Phaeodimeriella is related to the clade of Lentitheciaceae with moderate support. However, Phaeodimeriella differs from genera in Lentitheciaceae (see Mapook et al. 2016a). Boonmee et al. (2017) included this genus in the new family Phaeodimeriellaceae based on its morphology and phylogeny. Phaeodimeriella comprises three species, P. parvula, P. dilleniae and P. cissampeli
