Index Fungorum number: IF 551256; Facesofungi number: FoF 00389
Etymology: Refers to the name of the province in Italy where the fungus was collected.
Holotypus: MFLU 14-0692
Saprobic on decaying grass stems of Juncus sp. Sexual morph: Ascomata 211–282 μm high × 121–187 μm diam. (x̄ = 244 × 158 μm, n = 5), superficial, solitary, scattered, black, globose to subglobose, not easy to remove from host, neck long, black. Peridium 10–27 μm, 1-layered, composed of small, light brown to dark brown, thin-walled cells of textura angularis. Hamathecium comprising numerous, 1.1–1.9 μm wide, long cellular, septate, hyaline, pseudoparaphyses, branching above the asci. Asci 55–70 × 9–11 μm (x̄ = 64 × 10 μm, n = 10), 8-spored, bitunicate, fissitunicate, narrowly cylindrical, short pedicellate or apedicellate, apically rounded, with an ocular chamber. Ascospores 18–21 × 4–6 μm (x̄ = 19 × 5 μm, n = 15), 1–2-seriate, brown, ellipsoidal-fusiform, narrowly fusoid with rounded ends, or fusiform, usually 6-septate, the cells above central septum often broader than the lower ones, with mucilaginous sheath, smooth-walled. Asexual morph: Undetermined.
Material examined: ITALY, Ravenna Province, Marina Romea, on stems of Juncus sp. (Juncaceae), 28 November 2013, E. Camporesi IT 1544 (MFLU 14-0692, holotype), ex-type living culture, MFLUCC 14–0005.
