Bhatiellae rosae Wanas., Camporesi, E.B.G. Jones & K.D. Hyde, in Wanasinghe et al., Fungal Diversity: 10.1007/s13225-018-0395-7, [107] (2018)

Index Fungorum number: IF 554172; Facesofungi number: FoF 04014

Etymology: The specific epithet reflects the host genus Rosa.

Holotype: MFLU 16-0872..

Saprobic on Rosa. Sexual morph: Undetermined. Asexual morph: hyphomycetous forming on surface host epidermis. Sporodochia 80–100 μm high, 60–100 μm diam., with cushion-like pseudoparenchymatous cells at the base, composed of compact, fasciculate, foot-like cells at the base, with tightly aggregated, parallel, cylindrical conidiophores. Conidiophores 50–70 μm long × 4–6 μm diam (x̄ = 66.7 × 4.9 μm, n = 20), macronematous, mononematous, caespitose, erect to flexuous, unbranched, aseptate, torsive, brown to dark brown, smooth-walled, largely ampulliform at the base, undulated at the upper part. Conidiogenous cells polyblastic, sympodial, integrated, terminal, cylindrical, undulate, with large, cicatrized scars. Conidia 25–30 9 8–10 μm (x̄ = 27.7 × 9.3 μm, n = 50), acropleurogenous, solitary, simple, straight or moderately curved, cylindrical or ellipsoidal, brown to olivaceous brown when mature, euseptate, 5–8-distoseptate, smooth-walled, widest at the middle.

Material examined: ITALY, Province of Forli-Cesena [FC], Marsignano, Predappio, on dead aerial branches of Rosa canina (Rosaceae), 11 February 2016, Erio Camporesi IT 2814 (MFLU 16-0872, holotype); ex-type living culture, MFLUCC 17-0664.

GenBank Numbers: ITS: MG828873, LSU: MG828989, SSU: MG829101.

Notes: Bhatiellae rosae was collected from Rosa in Italy. This is the first assured hyphomycetous species in Phaeosphaeriaceae based on both morphological and multi-gene phylogenetic analyses.
