Tortula deciduidentata is known only from the type locality at Moller Bay and from Seguam Island, Aleutians (Bank 966, NY, as Gymnostomum calcareum). The perichaetial leaves have an excurrent costa with a truncate apex that appears apically discolored, but no deciduous parts were seen. This rare species is similar to 1a. Tortula cuneifolia var. blissii, and is further discussed there.
