Quatsinoporites

Quatsinoporites is an extinct monotypic genus of agaricomycet fungus in the Agaricomycetes family Hymenochaetaceae. At present it contains the single species Quatsinoporites cranhamii.

The genus is solely known from the Barremian aged, Apple Bay deposits of northwestern Vancouver Island. Quatsinoporites is one of only three known fossil fungus species found on Vancouver Island and the only to be described from the Apple Bay strata. The agaricomycete Appianoporites vancouverensis was described from an Eocene fossil at the same time as Quatsinoporites , while a third fungus, Margaretbarromyces dictyosporus was described three years later.

The genus is known only from the single holotype, a partial bracket fungus fruiting body, or "conk." The specimen, P13021 E, is currently residing in the paleobotanical collections housed by the University of Alberta, Edmonton, Alberta, Canada. The specimen was collected in Apple Bay, near Quatsino Sound on the northwestern shore of Vancouver Island, British Columbia, Canada. The partial conk was preserved in a calcareous nodule recovered from a Greywacke sandstone matrix equivalent in age to the Longarm Formation. The nodules formed in a shallow marine environment along with abundant plant material.
