Sterile cells globose to ovoid or irregular, 12–14 µm long, yellow-tinted; wall smooth, 1.5–2.5 µm thick.

Host family: Poaceae

Durán & Fischer (1961: 70) considered this to be a synonym of T. holci (Westend.) J.Schröt. (type on Holcus lanatus L., Belgium). Although they are similar, T. anthoxanthi has more meshes per spore diameter and lower muri than T. holci. The meshes in T. anthoxanthi are often incomplete to cerebriform and the interspaces lack verrucae, whereas T. holci has reticulate meshes with verruculose interspaces.
