Scytonema tolypothrichoides Kützing ex Bornet & Flahault (1886: 100) View in CoL Fig. 79 A–E.

Thallus flocculose, or forming small unstructured tuft-like clusters, rarely occurring as solitary filaments amongst other algae. Filaments 10–18 μm wide, with geminate false-branching; branches the same morphology as the main filaments. Sheath wide, colourless and slightly parallely lamellated with divergent layers towards the ends. Trichomes cylindrical, not constricted at the cross walls, ± widened towards the ends. Vegetative cylindrical, isodiametric or slightly longer or shorter than broad, 3.5–8.0 μm long × 4.0–6.5 μm wide, towards the ends shortened, isodiametric to shortly barrel-shaped; apical cells widely rounded. Heterocytes ± spherical, barrel-shaped to cylindrical, 5.0–11.5 μm long.

Specimens examined:—Maloney Springs

Other records:— Queensland: SE Queensland, McLeod (1975).

Observations:—Growing in small clusters amongst other algae in the shallows of tropical springs and shallow wetlands.
