Type species – Chaetorostrum quincemilense Zelski, Raja, A.N. Mill. & Shearer
Notes – The monotypic genus, Chaetorostrum was introduced by Zelski et al. (2011b) from woody debris in a semi-aquatic, intermittent stream in Peru. It is the first member of the Annulatascaceae that produces its asexual morph (taeniolella-like) in culture (Zelski et al. 2011b). There is no sequence data for this species and the family placement needs confirmation.
