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.[1]
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.[1]
