Microchaete sp. A Fig. 60 J–K View FIGURE 60 .

Filaments solitary, amongst other algae, straight or slightly arcuate, uniformly 7.0–8.5 μm wide along the entire length. Sheaths thin, firm, colourless, not lamellated. Trichomes cylindrical, distinctly constricted at the cross walls. Vegetative cells sub-spherical to barrel-shaped, rounded at the ends, 0.6–1.3 × longer than broad, 3.5–7.5 μm long × 5.0–6.5 μm wide, pale blue-green in colour. Heterocytes basal, ± spherical, 4.5–5.0 μm in diameter. Akinetes not observed.

Specimens observed:—Fat Hen Ck at Kilkivan.

Observations:—Growing amongst other algae attached to rocky substratum in a clear, shallow lowland stream. The sub-spherical vegetative cells are a distinctive feature of this material.
