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; Facesofungi number: FoF ***

Etymology: In honour of M.E. Barr, for her immense contribution to mycology.

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: Undetermined.

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

Notes: In our multi-gene phylogenetic analyses, strain MFLUCC 14-0652 of Allophaeosphaeria clematidis (Embarria clematidis in this study) groups with one of the novel strains, MFLUCC 14-0976. With both of these strains, forms a monophyletic lineage within Phaeosphaeriaceae with strong bootstrap support in the phylogenetic analyses. This clade has a sister relationship to Neosetophoma, but it is not statistically supported. Allophaeosphaeria clematidis and our new collection share similar morphological features and their dimensions of asci and ascospores are almost identical. Therefore, we introduce an additional strain for Allophaeosphaeria clematidis which was collected from Italy on Agrostis sp. and designate this clade as Embarria gen. nov.
