Peridium composed of membranaceous, brown cells of textura epidermoidea to textura angularis. Paraphyses absent. Asci 4- to 8-spored, unitunicate or bitunicate, broadly clavate, apex blunt to rounded and thickening, apical ring conspicuous after the ascospores released, pedicellate, evanescent. Ascospores overlapping at the apex, hyaline, aseptate to 1- or 2-septate, fusiform to cylindrical, sometimes slightly curved, smooth-walled, mostly with guttules. Asexual morph: Undetermined (adapted from Etayo 2002, Flakus et al. 2019).
Notes – Rhagadostomella, a lichenicolous genus, was introduced by Etayo (2002) based on R. gregaria from Colombia. A second species R. hypolobariella which has bitunicate asci and growing on Lobariella pallida in Bolivia was introduced (Flakus et al. 2019). This genus is placed in Nitschkiaceae but no molecular data is available for the Rhagadostomella (Etayo 2002, Flakus et al. 2019).
Type species: Rhagadostomella gregaria Etayo, Biblthca Lichenol. 84: 109 (2002)
Other accepted species: Species Fungorum – search Rhagadostomella.
