Wojnowiciella Crous, Hern. -Restr. & M.J. Wingf., Persoonia 34: 201 (2015).

Index Fungorum number: IF 812443; Facesoffungi number: FoF 01729, 9 morphological species (Species Fungorum, 2022), 9 species with molecular data.

Saprobic on host. Sexual morph: Ascomata dark brown to black, solitary, scattered, semi-immersed, slightly raised on the host surface, globose to subglobose, lacking ostiole. Peridium thin -walled, composed of 1–5 cell layers, of large, brown, pseudoparenchymatous cells, of textura angularis. Asci 8-spored, bitunicate, broadly cylindrical to sub-obclavate, short pedicellate, with indistinct ocular chamber. Ascospores overlapping 1–2-seriate, hyaline, fusiform, with acute ends, upper cell widely pointed, lower cell narrowly pointed, 1-septate, slightly constricted at the septum, smooth-walled (adapted from Karunarathna et al. 2017). Asexual morph: Conidiomata pycnidial, globose, brown, separate, non-papillate, but with central ostiole; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, hyaline to pale brown, smooth, ampulliform to subcylindrical, appearing phialidic. Microconidia occurring in same conidioma as macroconidia. Microconidiophores intermingled with macroconidiogenous cells, branched at the base, septate, subcylindrical, hyaline, smooth. Microconidiogenous cells terminal and intercalary, hyaline, smooth, ampulliform to subcylindrical, phialidic with periclinal thickening. Microconidia solitary, hyaline, guttulate, smooth, subcylindrical to ellipsoid, apex obtuse to subobtuse, base truncate. Macroconidia subcylindrical, straight to slightly curved, apex subobtuse, base truncate, septate, at times with 1–2 oblique septa, thick-walled, verruculose, guttulate, golden brown (adapted from Crous et al. 2015).


Type species: Wojnowiciella eucalypti Crous, Hern. -Restr. & M.J. Wingf.


Notes: Wojnowiciella was introduced by Crous et al. (2015) with W. eucalypti as type species. Wojnowiciella is characterised by pycnidial, globose, brown conidiomata, ampulliform to subcylindrical, phialidic conidiogenous cells, microconidiophores intermingled with macroconidiogenous cells, hyaline, smooth, ampulliform to subcylindrical, phialidic microconidiogenous cells, solitary, hyaline, guttulate, smooth, subcylindrical to ellipsoid microconidia and subcylindrical, straight to slightly curved macroconidia. Wojnowiciella differs from Wojnowicia in having non-papillate conidiomata lacking setae and having dark brown conidia. Wojnowiciella has microconidiophores intermingled with macroconidiogenous cells, that produce hyaline microconidia which is lacking in Wojnowicia. Karunarathna et al. (2017) reported the first sexual morph record of W. dactylidis. Wojnowiciella is morphologically and phylogenetically a well-defined genus in Phaeosphaeriaceae. Molecular markers available for Wojnowiciella include ITS, LSU, SSU, RPB2 and TEF1.
