Rhamphoria Niessl, Verh. nat. Ver. Brünn 14: 204 (1876)
Index Fungorum number: IF4690; 13 morphological species (Species Fungorum 2020), 3 species with sequence data.
Type species – Rhamphoria delicatula Niessl
Notes – Rhamphoria is characterized by black, astromatic, perithecial ascomata with a distinct papilla or rostrate neck, unitunicate asci with a J-, apical ring and hyaline, dictyospores that may produce ascoconidia while still in the asci (e.g. Rhamphoria pyriformis). The species in Rhamphoria are mainly separated by the size of ascospores, number of transverse and longitudinal septa and to a lesser degree on spore shape (Réblová & Štěpánek 2018).
