Notes: Catinella was established by Boudier (1907). Several authors have misidentified this fungus and placed it within Leotiomycetes (Durand 1922). However phylogenetic study of Greif et al. (2007) strongly supported its placement within Dothideomycetes. Catinella formed a distinct lineage within Dothideomycetes in Hongsanan et al. (2020), thus we introduced this new order to accommodate Catinella and allied species in the class Dothideomycetes. The divergence time for Catinellales is estimated as 163 MYA (Hongsanan et al. 2020).

Accepted families: Catinellaceae.
