Taxa are mostly saprobic in terrestrial and marine habitats and some are endophytes in plant roots (Ashrafi et al. 2018, Baral & Rämä 2015). Ascomata are apothecial. Apothecia are cupulate or rounded to elongated, sessile, erumpent or seemingly superficial, some are closed when immature and opening by slit-like or by lobes. The ectal excipulum is composed of cells of hyaline textura prismatica or textura angularis to globulosa and medullary excipulum is composed of cells of textura prismatica to porrecta. Paraphyses are filiform or lanceolate, apically slightly swollen, straight or flexuous and sometimes guttulate. Asci are mostly 8-spored, non-amyloid or amyloid and sometimes arising from croziers. Ascospores are ellipsoid to fusoid, aseptate or 1–3-sepatate and guttulate (Svrcek 1977b, 1976, 1982, Nannfeldt 1984, Baral & Räma 2015, Baral & Haelewaters 2015, Haelewaters et al. 2018, Ashrafi et al. (2018). Asexual morphs are hyphomycetous and sporodochial. Conidiogenesis is phialidic. Conidia are aseptate and globose to ellipsoid or fusoid (Jaklitsch et al. 2016).

Notes – In our phylogeny the genera Stamnaria, Belonioscyphella, Roseodiscus, Tetracladium, Cistella, Urceolella, Mycoarthris, Rodwayella, Psilachnum and Rommelaarsia, which were previously, classified under the other helotilian families, nested within Calloriaceae. Jaklitsch et al. (2016) suggested the genetic similarity of Tetracladium with Calloriaaceae.
