The monotypic genus Ophiodiaporthe was introduced by Fu et al. (2013) and is typified by O. cyatheae based on its unique characteristics. Phylogenetically, the genus is a closely related to Diaporthe in Diaporthaceae, Diaporthales, Sordariomycetes (Fu et al. 2013) where it is presently placed (Hyde et al. 2024c). Ophiodiaporthe cyatheae was reported as a pathogen responsible for causing a devastating wilt disease of Cyathea lepifera (Cyatheaceae, a tree fern) at high frequencies, as demonstrated by pathogenicity tests (Fu et al. 2013). The genus is charactered by its host preference for Cyathea lepifera and unique anamorph characteristics, producing a single type of conidia, which distinguishes it from the similar genus Diaporthe (Fu et al. 2013).
