Species: Tetrodontium brownianum

Mosses very small, dull, dark-green or brown, scattered, gregarious, or tufted, 1-1.25 mm high, simple, usually consisting at first of a cluster of polymorphous radical leaves (linear, linear-clavate, or oblong-linear, blunt to acute, often apiculate, sometimes irregularly forked, sinuolate to irregularly serrulate, ecostate or sometimes thickened at the base and along the middle forming an obscure costa), later producing a small budlike cluster of leaves enclosing the archegonia. Stem leaves appressed, obscurely 3-ranked, up to 1.2 mm long, oblong-lanceolate, acute, concave; margins erect, entire or irregularly serrulate above; costa weak, ending well below the apex, sometimes lacking (Crum and Anderson 1981).
