Basionym: Wojnowicia dactylidicola Wijayaw., Camporesi & K.D. Hyde, in Liu et al., Fungal Diversity: 10.1007/s13225-015-0324-y, [142] (2015) (Liu et al. 2015)

Index Fungorum number: IF 552973; Facesofungi number: FoF 03193

Etymology: Named after the host Dactylis.

Holotypus: MFLU 14-0743. (Description from Liu et al. 2015)

Saprobic on branch of Dactylis sp. Sexual morph: Undetermined. Asexual morph: Conidiomata 70–100 μm diam., 100–130 μm high, pycnidial, superficial, black, gregarious to solitary, unilocular, with an eccentric papillate ostiole. Pycnidial wall 18–20 μm wide, with thick outer layer, dark brown, 5–6 cell layered, with inner most layer hyaline, 2–3 cell layered, with cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 1–2.5 × 1.5–3 μm, simple, smooth, hyaline, short, integrated, holoblastic to phialidic. Conidia 25–35 × 3.5–6.5 μm (x̄ = 28.38 × 4.87 μm, n = 20), pale brown, fusiform to cylindrical, straight to curved, with obtuse apex and base, 3–5-septate, discrete, smooth-walled, guttulate.

Culture characters: Colonies on PDA olive brown from above and brown from reverse, with thin mycelium, zonate, slow growing, attaining a diam. of 2.5 cm in 7 days at 18 °C.

Material examined: Italy, Province of Forlì-Cesena, Fiumicello, Premilcuore, on dead branch of Dactylis glomerata L. (Poaceae), 15 March 2013, E. Camporesi, NNW IT1259 (MFLU 14-0743, holotype); ibid., (GUHC (Guizhou University Herbarium Collection) 7201, isotype), ex-type living culture, MFLUCC 13–0738, GUCC 11.

GenBank: ITS: KP744469, LSU: KP684147, SSU: KP684148.

Notes: Wojnowicia dactylidicola was introduced by Liu et al. (2015), however recent phylogenetic studies showed the ex-type strain of W. dactylidicola (MFLUCC 13-0738) clustered outside of the genus (Crous et al. 2015). In the present phylogenetic analysis, W. dactylidicola forms a sister clade to Galiicola pseudophaeosphaeria (MFLUCC 14-0524). Unfortunately, no asexual morph has been reported for G. pseudophaeosphaeria (Ariyawansa et al. 2015). However, we transfer W. dactylidicola to the genus Galiicola based on phylogeny (Thambugala et al. 2017).
