Suttonomyces rosae Phukhams., Camporesi & K.D. Hyde, in Wanasinghe et al., Fungal Diversity: 10.1007/s13225-018-0395-7,  (2018)
Index Fungorum number: IF554154; Facesofungi number: FoF 03995
Etymology: The specific epithet reflects the host genus Rosa.
Holotype: MFLU 18-0112.
Saprobic on Rosa. Sexual morph: Undetermined. Asexual morph: Conidiomata 64–110 μm diam. × 110–180 μm high (x̄ = 80 × 135 μm, n = 10), pycnidial, immersed, erumpent, solitary, globose, unilocular, black, with a long neck. Pycnidial wall 8–20 μm wide, multi–layered, with 3–5 outer layers of brown-walled cells of textura angularis, with inner layer thin, hyaline. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 2–9 × 1.8–6 μm (x̄ = 6.7 × 4.3 μm; n = 25), blastic, phialidic, discrete, determinate, hyaline, smooth. Conidia 9–12 × 5–8 μm (x̄ = 11 × 7 μm; n = 30), oblong, mostly straight, occasionally slightly curved, with 1–2-transverse septate, initially hyaline, later becoming brown to dark brown at maturity, rounded at both ends, smooth-walled.
Material examined: ITALY, Province of Forli-Cesena [FC], Converselle, Castrocaro Terme e Terra del Sole, on dried aerial spines of Rosa canina L. (Rosaceae), 27 November 2014, Erio Camporesi, IT 2260 (MFLU 18-0112, holotype), ex-type living culture, MFLUCC 15-0051.
GenBank Numbers: ITS: MG828973, LSU: MG829085, SSU: MG829185.
Notes: Suttonomyces rosae morphologically fits well within the generic concepts of Suttonomyces and closely resembles the type species, S. clematidis in having blastic, phialidic, discrete, determinate, hyaline conidiogenous cells and camarosporium-like conidia. However, they are different as paraphyses are present in Suttonomyces clematidis, while paraphyses have not been observed in S. rosae.
