Fraxinicola Crous, M. Shen & Y. Zhang ter, gen. nov.

Index Fungorum number: MB831518; Facesoffungi number: FoF 12061

Etymology: Named after the host genus on which it mostly occurs, Fraxinus. “-icola” means dweller, inhabiter.

In vivo: Ascomata scattered over the entire leaf surface, immersed, globose to subglobose, pseudoparaphysate, ostio- late, papillate, with or without setae. Peridium thin, composed of pigmented cells of textura angularis. Asci bitunicate, oblong to obclavate, with a short pedicel. Ascospores uniseriate, partially overlapping to biseriate, especially at the base, ellipsoidal, with broadly rounded ends, olivaceous pale brown, 1-septate, slightly constricted at the septum, the upper cells often shorter and wider than the lower ones, smooth-walled. Conidiophores fusicladium-like, arising in clusters (sporodochia) from erum- pent subcuticular to intraepidermal, few-celled stromata, or from terminal or lateral hyphae in culture, erect, unbranched, geniculate, septate, dark brown, smooth, walls thickened. Sporodochia interconnected by subcuticular to intraepidermal mycelium of melanised, partly swollen short cells and inter- cellular chlamydospores. Conidiogenous cells terminal, genic- ulate, proliferation sympodial, with a few to numerous truncate loci, somewhat refractive or darkened. Conidia solitary, smooth, lanceolate but apical tip rounded, 0 – 2-septate, pale medium brown, with a truncate base which is often somewhat thickened (adapted from Aderhold 1897, Crous et al. 2011, Ibrahim et al. 2016).
