Kumanoa tiomanensis (Kumano & Ratnasabapathy) Necchi & M.L. Vis  

"Plants moderately mucilaginous, rigid; branching pseudodichotomous and abundant; apices straight, apical cells embedded within the fascicles; 2.0-5.0 cm high, 150-300 µm in diameter. Whorls well developed, usually distinct and separated, obconical or barrel-shaped, compressed and indistinct in older parts. Internode 150-300 µm long. Pericentral cells spherical with 1-2 primary fascicles; rhizoidal filaments well developed, forming 2-3 layers of cylindrical cells. Primary fascicles audouinelloid, curved, 10-15 cell-storeys, proximal cells cylindrical, L/D 2.5-5.0; distal cells cylyndrical or barrel-shaped, L/D 1.5-3.0; branching unilateral. Secondary fascicles abundant, curved, covering the entire internode and as long as primary fascicles.

Monoecious. Spermatangia spherical or obovoid, terminal or sub-terminal on primary or secondary fascicles, 4.0-6.0 µm in diameter. Carpogonial branches helically twisted, arising from pericentral cells, composed of 5-10 disc- or barrel-shaped cells; involucral filaments short, 1-3 cell-storeys; carpogonia 35.0-45.0 µm long; trichogynes club-shaped or elliptical, unstalked, 7.0-10.0 µm in diameter. Carposporophytes 1 per whorl, dense, semi-spherical, lower than the whorl radius, 80-220 µm in diameter, 35-190 µm high; gonimoblast filaments 3-6 cell-storeys; cells cylindrical or barrel-shaped; carposporangia spherical or sub-spherical, 8.0-12.0 µm long, 6.0-10.0 µm in diameter."
