Neogloeosporidina pruni

Neogloeosporidina pruni W.J. Li, Camporesi & K.D. Hyde, sp. nov.

Index Fungorum number: IF557153, Facesoffungi number: FoF 07476, Fig. 251

Etymology: Named after the host from which it was collected, Prunus.

 

Saprobic on dead stems of Prunus avium (Rosaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 100–400 µm diam., 90230 µm high, brown, eustromatic, pycnidial, scattered, rarely gregarious, subepidermal or subperidermal in origin, immersed to partly erumpent, globose to subglobose, unilocular, thick-walled, smooth, glabrous. Ostiole absent, dehiscing by an irregular rupture in the apical wall, then becoming wide open. Conidiomata wall 20–30 µm wide, composed of brown, thick-walled cells of compressed textura angularis, Conidiophores mostly reduced to conidiogenous cells, occasionally present, short, cylindrical, septate and branched at base, formed from inner layers of conidiomata. Conidiogenous cells 10–35 × 2.1–3.9 µm, hyaline, enteroblastic, cylindrical, discrete or integrated, indeterminate, smooth-walled. Conidia 11–18 × 4.5–9 µm ( = 14 × 6.9 µm; n = 30), hyaline, ellipsoid to ventricose, often with a blunt apiculus, unicellular, thick-walled, smooth.
