Index Fungorum number: IF 3746; Facesoffungi number: FoF 02323, 1 morphological species (Species Fungorum 2021), molecular data unavailable.
Saprobic or pathogenic on leaf. Sexual morph: Ascostromata epiphyllous, superficial, black, discrete, irregularly suborbicular, flat end-convex, with radiate ridges marking the position of the loculi, plurilocular, connected with the hypostroma in the epidermal cells of the leaf by numerous single hyphae which penetrate the cuticle. From the innermost cells of the hypostroma, 1-3 irregularly branched continuous hyphae penetrate the palisade cells and sometimes those of the mesophyll. Loculi numerous, opening linearly along the radiate ridges. Asci numerous, 8-spored, erect, ellipsoid to obovoid, rounded at the apex, sessile or shortly stipitate. Paraphyses branched. Ascospores conglobate or obliquely biseriate, smooth, brown, pyriform, unequally 1-septate, with the upper cell longer and broader than the lower cell, constricted at the septum. Asexual morph: Unknown. (Adapted from Sivanesan 1971).
Type species: Parmulariopsella burseracearum Sivan.
Notes: Parmulariopsella was introduced by Sivanesan (1971) with P. burseracearum as type species. Parmulariopsella differs from Parmularia in the way of attachment of the ascostromata. In Parmularia, the ascostromata has a not-like attachment consisting of several rows of cells while in Parmulariopsella the epistroma is linked to the hypostroma by numerous single hyphae rising from the uppermost cells of the hypostroma in the epidermis, in the presence of very much branched hyphae penetrating the palisade and sometimes the mesophyll cells, branched paraphyses and in the un equally septate ascospores. Sequence data is lacking for the genus.
