Cancellidium is characterized by shiny, obovate to obcordate conidia which are composed of parallel rows of cells encapsulating strings of monilioid cells (Tubaki 1975, Yeung et al. 2006). Since the type species C. applanatum was sequenced (Pratibha et al. 2014, Zelski et al. 2014), more species were added to the genus and the placement of Cancellidium was discussed accordingly. Cancellidium was referred to Sordariomycetidae genera incertae sedis (Hyde et al. 2020), later was classified in a newly established family Cancellidiaceae based on a divergence time study (Hyde et al. 2021). The sexual morph of Cancellidium is unknown. We introduce a new asexual species in the genus and provide several new collections of C. atrobrunneum and C. griseonigrum. 

Type species – Cancellidium applanatum Tubaki.

Other accepted species: Species Fungorum – search Cancellidium.
