Wilsonomyces
Wilsonomyces Adask., J.M. Ogawa & E.E. Butler, Mycotaxon 37: 283 (1990).
Index Fungorum number: IF 11250; Facesoffungi number: FoF 07942, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Pathogenic on host. Sexual morph: Unknown. Asexual morph: Conidiomata sporodochial, usually punctiform, tan to olivaceous brown, becoming black on maturity. Stroma present in host tissue, compact, immersed, erumpent, discoid on leaves, fusoid on twigs. Conidiophores macronematous, mononematous, densely compacted, straight or flexuous, branched or not, subcylindrical, geniculate, smooth, subhyaline to pale brown, cicatrized, 1–4-septate. Conidiogenous cells terminal and intercalary, subcylindrical, subhyaline, smooth, proliferating sympodially at apex, scars unthickened. Conidia holoblastic, solitary, dry, acrogenous, simple, thick-walled, cylindrical, clavate, ellipsoidal or fusiform, occasionally forked, rounded to acute at the apex, truncate at the base, generally (2–)3–5(–10) transverse with occasionally 1–2 oblique septa, rarely with 1 longitudinal septum, subhyaline, becoming medium brown to golden-brown, dark olivaceous to black in mass, conidia in vivo are larger (adapted from Adaskaveg et al. 1990).
Type species: Wilsonomyces carpophilus (Lév.) Adask., J.M. Ogawa & E.E. Butler
Notes: Wilsonomyces was introduced by Adaskaveg et al. (1990) with W. carpophilus as type species. Wilsonomyces is characterised by sporodochial, usually punctiform conidiomata, macronematous, mononematous conidiophores, terminal and intercalary, subcylindrical, subhyaline conidiogenous cells and holoblastic, solitary, dry, acrogenous conidia. Sutton (1997) synonymized Thyrostroma into Wilsonomyces. Marin-Felix et al. (2017) confirmed that Thyrostroma and Wilsonomyces are distinct based on multigene phylogenetic analysis of LSU, ITS and tef1 sequence data. Wilsonomyces is a distinct genus in Dothidotthiaceae. Molecular markers available for Wilsonomyces are ITS, LSU and TEF-1.
