Description

Ophiocordycipitaceae G. H. Sung, J. M. Sung, Hywel-Jones & Spatafora, 2007.

Ophiocordyceps Petch, 1931.

Notes.

Ophiocordyceps (Ophiocordycipitaceae) is a genus of entomopathogenic fungi encompassing over 350 species (Hyde et al. 2024; Index Fungorum 2025). This genus was originally treated as a subgenus under Cordyceps by Petch (1931) until it was redefined as a distinct genus through multigene phylogenetic analyses by Sung et al. (2007). Species in this genus exhibit diagnostically dark, fibrous to wiry stromata with variable morphologies (clavate, filiform, or branched) and perithecia that are either superficially exposed or embedded within the stromatal matrix. The asci are typically cylindrical and bear prominent apical caps, while the ascospores are generally cylindrical, multiseptate, and may either disarticulate into part-spores or remain intact after discharge (Sung et al. 2007; Ban et al. 2015). Host specificity spans diverse arthropods, parasitizing larvae of Lepidoptera, Coleoptera, Hymenoptera, Hemiptera, Diptera, and arachnids (Kobayasi 1941; Mains 1958; Ban et al. 2015). Quandt et al. (2014) present a concise, thorough, phylogenetically relevant, and taxonomically accurate revision of the family Ophiocordycipitaceae. In this study, we introduce two new species (O. jinguangensis and O. northeastensis) based on phylogenetic and morphological analyses.
