Setae short; capsules immersed or emergent, erect, ovoid from a short, thick neck, narrowed at the mouth, smooth; annulus persistent, consisting of thick-walled cells; operculum slightly convex, long-rostrate; peristome none. Spores large, subreniform, spinose. Calyptrae campanulate-mitrate, covering about half the urn.
