The genus was considered to be similar to Schizothyrium, but it differs in having subcuticular ascomata, while Schizothyrium has epicuticular ascomata (Kohlmeyer et al. 1998). Doilom et al. (2018) re-examinded the holotype specimen of Rivilata ius and included Rivilata in Phaeothecoidiellaceae and noted that it is similar to Translucidithyrium. Rivilata is characterized by brown, flattened thyriothecia, developing under the cuticle and becoming superficial, a hymenium covered by an epithecium, and ellipsoidal, uniseptate, upper cell, wider than the lower one, and hyaline ascospores, with oil droplets (Doilom et al. 2018).

Type species: Rivilata ius Kohlm., Volkm.-Kohlm. & O.E. Erikss., Can. J. Bot. 76(3): 472 (1998).

Other accepted species: Species Fungorum – search Rivilata.
