Note that the 1953 bryozoan Treatise lists Chasmatopora as a junior synonym of Subretepora, a trepostome. Anstey and Wilson (1996) list Chasmatopora, as well as the closely related Phylloporina, both members of the Phylloporinina (Order Fenestrida) as occurring in the Ordovician of Ohio. They do not list Subretepora.
