Type species – Botryotrichum piluliferum Sacc. & Marchal
Notes – Botryotrichum has rarely been reported (Kirk et al. 2008, Wijayawardene et al. 2018a). Based on the phylogenetic analyses of ITS, LSU, rpb2 and tub2 gene regions, Wang et al. (2016a) re-organized the genus and included some species of the genera Emilmuelleria and Chaetomium. The genus is characterised by superficial, subglobose to ovate, olivaceous, ostiolate or ascomata lacking ostioles, with flexuous or undulate, often circinate, unbranched, lateral seta-like hairs, fusiform, long pedicellate, evanescent asci and fasciculate, olivaceous brown, ellipsoidal- fusiform ascospores, with an apical germ pore. Conidiophores are setose, terminating in setae, branched, macronematous with clusters of thick-walled conidia that have a conspicuous germ pore (Wang et al. 2016a, 2019b).
