Scytonematopsis kashyapii (Bharadwaja) Geitler (1935: 445) Fig. 81 A–J.
Basionym: Spelaeopogon kashyapii Bharadwaja (1928: 69)
Thallus a tufted woolly prostrate mat; filaments rarely solitary, straight or flexuous, narrowed towards the ends with solitary or geminate false-branching; sheaths conspicuous, hyaline, firm and colourless. Trichomes slightly constricted at the cross walls. Vegetative cells barrel-shaped to long-cylindrical, 1.5–4.5 × longer than broad, 9.3–19.0 μm long × 4.3–6.5 μm broad; terminal cells slightly conical. Heterocytes intercalary, single or two in series, ellipsoidal to cylindrical, 9.6–24.0 μm long × 5.0–9.5 μm broad.
Specimens examined:—Pool Ck at Talaroo.
Observations:—Originally described growing on aquatic plants in pools and a small lake in India, also known from Indonesia. The material observed from Talaroo is consistent with the original description both in terms of the morphology and habitat.
Other species known from Australia: Queensland: S. pilosa (Harvey ex Bornet & Flahault) I.Umezaki & M.Watanabe (1994: 311) , Clump Point, East of Tully ( AD-A 64880 ) .

Type: Stigonema Agardh ex Bornet & Flahault (1886: 62)
Thallose, filamentous, with true branching. Filaments and branches generally undifferentiated, sometimes narrowed towards filament apices. Filaments torulous or moniliform, encased in a firm, lamellated and often coloured sheath. Trichomes mono- to polyseriate, composed of sphaeroid or irregularly rounded vegetative cells. Heterocytes intercalary or lateral, often terminal in hormogonia or immature filaments. Akinetes known from several species, but not well characterised. Reproduction by disintegration of thallus and production of hormogonia.
