OMEWHAT resembling the Grimmia Family, but nearly always growing on trees. The plants are small, rarely reaching an inch in height and usually much shorter, blackish or brownish green below. The leaves are oblong- or linear-lanceolate and usually very hygro- scopic. The calyptra is nearly always hairy and the capsules often immersed, with very distinct longitudinal wrinkles when dry and empty. The peristome usually consists of i6 rather short teeth which are nearly al- ways reflexed when dry and are often united in pairs; the inner peristome is usually represented by i6 slender hairlike proc- esses, almost too minute for the hand-lens. In the First Edition this family was united with the Grimmiaccac. Mem- bers of these two families may become so dry and brittle as to crumble to dust in the fingers and yet retain their vitality un- impaired, springing into re- newed growth with the next Figure 28.
