Wojnowicia dactylidis Wijayaw., Camporesi & K.D. Hyde, in Liu et al., Fungal Diversity: 10.1007/s13225-015-0324-y, [144] (2015)

Holotype: ITALY, Province of Forlì-Cesena, Teodorano, Meldola, on dead branch of Dactylis glomerata L. (Poaceae), 7 March 2013, E. Camporesi, NNW IT1101 (MFLU 14–0745), ex-type living culture, MFLUCC 13–0735, GUCC9.

Saprobic on dead stem of Galium sp. Sexual morph: Undetermined. Asexual morph: Conidiomata 195–220 μm diam., 210–250 μm high, pycnidial, semi-immersed in the host tissue, scattered, solitary, non-papillate, brown. Pycnidial walls 22–28 μm thick, composed of several layers of light brown to dark brown cells, arranged in textura angularis to textura prismatica. Conidiophores absent. Conidiogenous cells formed on the inner layer of conidiomata, ampulliform, phialidic, smooth, pale brown. Conidia 30–42 × 5–7 μm (= 35.8 × 6.2 μm, n = 20), cylindrical, straight to slightly curved, gradually tapering towards the rounded apex, with rounded apex, initially hyaline to pale brown, after maturity golden brown, 7–10-euseptate, thin-walled, with pad-like appendages at the apex.

Culture Characteristics: Colonies on PDA reaching 8 mm diam. after 2 weeks at 25–30 °C, colonies medium dense, circular, convex, surface slightly rough with edge entire, effuse, velvety to hairy, margin well-defined, colony from above: white to grayish at the margin, white at the centre reverse, white to grayish at the margin, white to greyish at the centre, mycelium white to greyish with tufting, not producing pigments in PDA.

Material examined: ITALY, Province of Forlì-Cesena [FC], Berleta - Santa Sofia, on dead aerial stem of Galium sp. (Rubiaceae), 17 May 2015, E. Camporesi, IT 2487 (MFLU 16–1366, HKAS93706), living Culture KUMCC 15–0560.

Known hosts and distribution: Dactylis glomerata L. (Poaceae) (Liu et al. 2015).

GenBank Numbers: ITS: MN750612; LSU: MN750591; SSU: MN750606.

Note: As morphological characters examined largely overlap with Wojnowiciella dactylidis (Wijayaw., Camporesi & K.D. Hyde) Hern.-Restr. & Crous, we therefore report our collection as a new host record of W. dactylidis from dead aerial stem of Galium sp. (Rubiaceae). Both collections share similar morphological characters, viz. semi-immersed, scattered, solitary conidiomata and pale brown, cylindrical, 7–10-septate conidia (Liu et al. 2015). Wojnowiciella dactylidis was initially introduced by Liu et al. (2015) as Wojnowicia dactylidis Wijayaw., Camporesi & K.D. Hyde, based on both morphology and phylogeny. Some Wojnowicia species (W. dactylidis, W. lonicerae Wijayaw., Camporesi & K.D. Hyde and W. spartii W.J. Li, Camporesi & K.D. Hyde) were transferred to Wojnowiciella by Hernández-Restrepo et al. (2016). Combined multi-gene (LSU, SSU, ITS and TEF1-α) based phylogenies also confirmed that our collection clusters with other Wojnowiciella species, in particular W. dactylidis (MFLUCC 13–0735) with high support (89% ML, 0.99 BYPP).
