Index Fungorum number: IF 554231; Facesofungi number: FoF 04012
Saprobic on Agrostis stolonifera L. Sexual morph: Ascomata 130–170 μm high 150–200 μm diam. (x̄ = 157.1 × 168.9 μm, n = 5), 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 5–10 μm wide at the base, 10–15 μm wide at the sides, with 2–3 layers, heavily pigmented, brown to dark brown cells of textura angularis. Hamathecium comprising numerous, 1.5–2.5 μm wide, filamentous, branched, septate, pseudoparaphyses. Asci 75–90 × 18–22 μm (x̄ = 81 × 21 μm, n = 30), 8-spored, bitunicate, fissitunicate, clavate, short pedicellate, thick-walled at the apex, with minute ocular chamber. Ascospores 20–25 × 9.5–11 μm (x̄ = 23.5 × 10.7 μm, n = 50), 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, surrounded by a thick mucilaginous sheath. Asexual morph: Undetermined.
Material examined: ITALY, Province of Forli-Cesena [FC], Montecoronaro, Verghereto, on dead aerial stems of Agrostis stolonifera L. (Poaceae), 26 July 2014, Erio Camporesi IT 2015 (MFLU 16-0212, new host record); ex-type living culture, MFLUCC 14-0976.
GenBank Numbers: ITS: MG828871, LSU: MG828987, SSU: MG829099, TEF: MG829194.
Notes: Embarria clematidis is similar to taxa in Dematiopleospora in ascospore shape and septation, but they differ in ascomata characters as Dematiopleospora has brown setae on their ostioles, while setae are absent in Embarria clematidis.
