Cryptomitrium is a genus of complex thalloid liverworts in the family Aytoniaceae. The genus name means “hidden turban” in reference to the inconspicuous sheath around the immature sporangium.[2]
Description
Sporophyte bearing receptacles are unlobed on elongate, somewhat grooved stalks, which appear pale throughout or brownish purple near the base. The receptacle is a convex-expanded disc, thinning towards the margins.[2]
Mature sporangia are brown, nearly spherical with very short seta, three to seven per receptacle, each opening by a lid-like operculum. The sporangia mature in early spring.[2]
Species
This genus includes the following species:[1][3]
- Cryptomitrium himalayense Kashyap
- Cryptomitrium oreades Perold
- Cryptomitrium tenerum (Hook.) Austin ex Underw.
