Sexual morph ascomata: 125-267 mm high, 110-300 mm in diam, ampulliform to subglobose, immersed, confined to cystocarps and tetrasporic pustules of Chondrus crispus, ostiolate, papillate, coriaceous, pale, except for the black pseudoclypeus, gregarious. Peridium: composed of interwoven hyphae, small-celled, indistinct above, particularly in the ostiolar region. Necks: elongate, conical or cylindrical. Pseudoparaphyses: thin, septate, simple or branched, attached at both ends. Asci: 70-94 x 10-15 mm, 8-spored, subcalvate to subcylindrical, short pendunculate, thick-walled, bitunicate, physoclastic; developing at the base and lower side of the ascomata venter. Ascospores: 33-40 x 5-7 mm, irregularly biseriate, elongate fusiform, 1-septate below the center; lower cell cylindrical, rounded; upper cell broad in the lower half and pointed apically; slightly constricted at the septum, hyaline, but also becoming pale yellowish in age, no sheath or appendages. Spermagonia: 100-192 x 63-113 mm. Spermatiophores: 16-18 mm long. Spermatia: 4 x 1 mm, oblong to ellipsoidal, 1-celled, hyaline, originating in mucilaginous, basipetal strings at the apices of the spermatiophores. The genus is monotypic (Jones et al., 2009a). Asexual morph: Undetermined (Description: Based on Kohlmeyer & Kolhmeyer (1979)).
