178:, which in this species is pale green, flattened, dichotomously branched, thin, and somewhat shiny, measuring 0.6 to 1.5 cm long, less than 1 cm wide. The thallus margins are brownish purple in patches and somewhat undulate, curling upward when dry. The dorsal surface has a faint pattern of irregular polygons, and around inconspicuous pores to the air chambers below. The ventral surface is dark purple, shiny towards the margins, and green medially. The ventral scales are small, dark, and purple, poorly developed at maturity. The peculiar oil bodies found in so many liverworts are found scattered throughout the thallus, ventral scales, and sporogonial receptacle. Cryptomitrium does not reproduce asexually via

It usually reaches its best development in
February or March, depending on the amount and distribution of the winter rainfall. During the long rainless season the plants dry up, the tips reviving and giving rise to new plants with the advent of the autumn rains.

Wildfires are suspected to play a role in maintaining habitat. Capsules develop in late winter to early spring, depending on elevation. It is a poor competitor with vascular plants and populations tend to disappear as succession progresses.
