Embarria

Embarria Wanas., Camporesi & K.D. Hyde, in Wanasinghe et al., Fungal Diversity: 10.1007/s13225-018-0395-7, [119] (2018).

 Index Fungorum number: IF 554169; Facesoffungi number: FoF 08331, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic in terrestrial habitats. Sexual morph: Ascomata immersed to erumpent, solitary, scattered, globose or subglobose, dark brown to black, coriaceous, ostiolate. Ostiole papillate, inconspicuous or in a shallow depression, black, smooth, comprising brown cells. Peridium with 2–3 layers, heavily pigmented, thin-walled, comprising brown to dark brown cells of textura angularis. Hamathecium comprising numerous, filamentous, branched, septate, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, clavate, short pedicellate, thick-walled at the apex, with minute ocular chamber. Ascospores overlapping biseriate, muriform, cell above central septum widest, hyaline when young, becoming dark brown at maturity, ellipsoidal to fusoid, asymmetrical, with one side flattened, muriform, with 4–6-transverse-septate and 1-longitudinal-septum except at the end cells, constricted at the septa, conical and narrowly rounded at the ends, slightly curved, guttulate, with smooth surface, with or without a thick mucilaginous sheath. Asexual morph: Unknown (adapted from Wanasinghe et al. 2018).

Type species: Embarria clematidis (Wanas., Camporesi, E.B.G. Jones & K.D. Hyde) Wanas. & K.D. Hyde

Notes: Embarria resembles Dematiopleospora in ascospore shape and septation, but they differ in ascomatal characters. Embarria lacks setae while Dematiopleospora has brown setae on their ostioles. Embarria is morphologically and phylogenetically a distinct and well-defined genus in Phaeosphaeriaceae. Molecular markers available for Embarria include ITS, LSU, SSU, TEF-1 and RPB2.
