Neosetophoma clematidis Wijayaw., Camporesi & K.D. Hyde, in Liu et al., Fungal Diversity: 10.1007/s13225-015-0324-y, [140] (2015)
Index Fungorum number: IF 505909; Facesofungi number: FoF 00419
Etymology: Named after host onwhich itwas first collected
Holotypus: MFLU 14–0746
Saprobic on branch of Clematis vitalba. Sexual morph: Undetermined. Asexual morph: Conidiomata 425–475 μm diam., 220–270 μm high, pycnidial, superficial, black, gregarious, unilocular, but occasionally multi-locular, with a papillate ostiole. Pycnidial wall 30–55 μm wide, thick at outer layer, brown to dark brown, with 4–10 cell layers, inner layer hyaline, 3–5 cell layers, cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 3–5 × 1–3 μm, simple, smooth, hyaline, integrated, enteroblastic, phialidic. Conidia 11–15 × 2–4 μm (x̄ = 12.71 × 2.95 μm, n = 20), slightly brown, straight to curve, continuous, with truncate base, with obtuse apex, 3-euseptate, often slightly narrower in the middle, smooth-walled, guttulate.
Culture characters: on PDA white from above and greyish white from reverse, cottony, circular, zonate, slow growing, attaining a diam. of 1.5 cm in 7 days at 18 °C.
Material examined: Italy, Province of Forlì-Cesena, Pietrapazza, Bagno di Romagna, on dead branch of Clematis vitalba L. (Ranunculaceae), 20 January 2013, E. Camporesi, IT1027 (MFLU 14-0746, holotype); ibid., GUHC 7204, isotype), ex-type living culture, MFLUCC 13-0734, GUCC 20.
GenBank: ITS: KP744450, LSU: KP684153, SSU: KP684154.
Notes: The phylogenetic tree showed that this species belongs to Neosetophoma and is a different species to N. italica and N. samarorum.
