Description

Chroococcus cf. varius A. Braun in Rabenhorst (1876: 2451) (Figs. 5H–5I).

Round, elliptical to irregular colonies, 8.8–17.4 µm diam., 2–4–8 celled, forming packets. Sheath firm, hyaline, conspicuous, distinctly lamellate to non-lamellate, smooth. Cells spherical to hemispherical, 2.5–4.2 µm diam. Cell content homogeneous to slightly granulated, olive green to yellowish.

Habitat: —Dry wood and tree bark.

Notes: —The present population is different from C. varius in relation to habitat, since it was found on wood and it is typically described from rocks (Komárek & Anagnostidis 1998).
