Type species – Wilsonomyces carpophilus (Lév.) Adask., J.M. Ogawa & E.E. Butler, Mycotaxon 37: 283 (1990).
≡ Helminthosporium carpophilum Lév., Annls Sci. Nat., Bot., sér. 2 19: 215 (1843).
Notes – Wilsonomyces was established by Adaskaveg et al. (1990) as a monotypic genus with W. carpophilus as the type. Sutton (1997) treated Thyrostroma as a synonym of Wilsonomyces. However, molecular studies based on three nuclear genes (Marin-Felix et al. 2017) shows that Wilsonomyces carpophilus groups away from Thyrostroma compactum and they are morphologically different as well, and hence they are not congeneric.
