Wojnowiciella Crous, Hern. -Restr. & M.J. Wingf., Persoonia 34: 201 (2015).
Saprobic on host. 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. Sexual morph: Unknown (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 characterized 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. Wojnowiciella is morphologically and phylogenetically a well-defined genus in Phaeosphaeriaceae. Molecular markers available for Wojnowiciella include LSU, SSU, ITS, RPB2 and TEF1.
