Description: taken from Ariyawansa et al. (2015)

Saprobic on dead branch of Vitis vinifera L. Sexual morph: Undetermined. Asexual morph: Conidiomata 220–239 μm high × 154–202 μm (x̄ = 237 × 177 μm, n = 10) diam., solitary, pycnidial, unilocular, scattered, immersed to erumpent, subglobose, dark brown to black. Pycnidial wall 13–35μm (−40μm at apex), externally merging with host tissues, composed of brown cells of textura angularis with a hyaline inner lining bearing conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 2–10 × 2–9 μm (x̄ = 4×5 μm, n = 20) diam., enteroblastic, phialidic, determinate, solitary, doliform, smooth-walled, hyaline. Conidia 7–12 × 2–6 μm (x̄ = 9 × 4 μm, n = 50), initially hyaline, dark brown at maturity, oblong, sub-fusiform, occasionally curved at the apex, with slight abscission scar at base of conidia, with 1–3 longitudinal septa, constricted at some septa, narrowly rounded at both ends, smooth-walled.

Culture characteristics: Colonies on PDA reaching 20 mm diam. after 4 weeks at 16 °C, cream to orangish-white at the margins; reverse white to cream and orangish white at the center, medium dense, circular, umbonate, fimbriate, fluffy, slightly radiating in the lower part, without diffusible pigments.

Material examined: ITALY, Province of Forlì-Cesena, near Galeata, on dead branch of Vitis vinifera (Vitaceae), 16 October 2014, E. Camporesi (MFLU 15–1404, holotype), (isotype in HKAS, under the code of HKAS88971), ex-type living culture, MFLUCC 15–0039.

GenBank Numbers: ITS: KT305997, LSU: KT305993, SSU: KT305995.

Note: Ariyawansa et al. (2015) introduced Floricola viticola to Floricolaceae and Jaklitsch et al. (2016) provided a new combination as Teichospora viticola to Teichosporaceae.
