Lombard et al. (2016) established Grandibotrys for two stachybotrys-like taxa with large, olivaceous green to dark brown conidia that have a mammiform apical and/or basal protrudance. Furthermore, they clustered distantly from the Stachybotrys s.st clade in cmdA-ITS-rpb2–tub2 phylogeny (Lombard et al. 2016). Grandibotrys is characterized by macronematous mononematous conidiophores occur solitary or in groups, are erect, septate, unbranched or branched, hyaline with thin and smooth walls. The whorls of 2–4 conidiogenous cells arise from the apex of the conidiophores. They are phialidic, subcylindrical to clavate to fusiform, hyaline and smooth-walled with visible collarettes. The conidia are aseptate, olivaceous green to dark brown, limoniform to ellipsoidal with a mammiform apex and a rounded base. They have thick and smooth walls. The sexual morph remains undetermined (Lombard et al. 2016). Grandibotrys species are saprobes that occur on decaying woods (Lombard et al. 2016; Hyde et al. 2017). This genus includes three species (Lombard et al. 2016; Hyde et al. 2017).
