van der Linde et al. (2016) introduced the monotypic genus Aureovirgo to accommodate A. volantis, based on ITS, LSU, and tub2 markers. Aureovirgo volantis associated with Cyrtogenius africus galleries in diseased Euphorbia ingens (van der Linde et al. 2016). Bases of immature ascomata are honeycolored and become fuscous when mature with dark necks. Ostiolar hyphae are hyaline. Ascospores are allantoid that have ellipsoidal sheaths. Aureovirgo forms a leptographium-like asexual morph. Conidiophores are mononematous and hyaline, with a simple and cylindrical stipe. Conidia are oblong-elliptical and oval ovate (van der Linde et al. 2016). Aureovirgo is phylogenetically most closely related to Graphilbum and species in the Sporothrix lignivora complex (van der Linde et al. 2016).
