Description

Endophytic or saprobic on Arundo plinii (Poaceae, Monocotyledons). Sexual morph: Unknown. Asexual morph: Conidiomata 90–150 μm diam., 130–180 μm high, pycnidial, subepidermal to superficial, solitary to gregarious, globose or subglobose, unilocular, dark brown to black. Conidiomata wall 20–30 μm thick, several-layered, outer layer thick in above, thin at bottom, composed of thick-walled, brown cells of textura angularis, inner layer composed of thin-walled, hyaline cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 2–5×1–3 μm, holoblastic, proliferating 1–2 times percurrently but mostly only 1 time, cylindrical to funnel-shaped, unbranched, discrete, indeterminate, hyaline to pale brown, smooth. Conidia 6–10 × 4–6 μm (x = 9.3 × 4.5 μm, n = 20), ellipsoidal or oblong to irregular, rounded apex, truncate base, 0–1-septate, pale to dark brown, guttulate or eguttulate, thin-walled, verrucose.

Material examined: Italy, Forlì-Cesena [FC] Province, near Bertinoro, on dead stems of Arundo plinii Turra (Poaceae), 4 March 2012, Erio Camporesi, NTIT148 (MFLU 13–0315, holotype).
