Mniodendron comatum has a prostrate, creeping primary stem that forms erect secondary branches (stipes) with a dense tomentum of rhizoides. Stipes terminate in an umbrella-like frond. Fronds are pinnately branched (branches regularly arranged in one plane to either side of the frond axis) and bear long tapering leaves. Mniodendron comatum can be distinguished from related species with a similar tomentum by the large number of sporophytes with rather short setae. Formerly Hypnodendron comatum.
An endemic moss found on damp earth in shaded forest.
