Orthotrichum hallii is found on rock at middle to upper elevation. The leaves are acute at the apex without an awn. The leaves are erect when dry and spreading when wet. The stomata are immersed. The most striking feature though of O. hallii is the completely bistratose distal lamina, a feature absent in most of the other members of the family.
