Description

Gloeocapsa stegophila (Itzigsohn) Rabenhorst (1863: 72) (Figs. 9J–9K).

Basionym: Monocapsa stegophila Itzigsohn in Rabenhorst (1853: 263 a).

Round to elongated colonies, 7.2–32.8(57.7) µm diam., 2–4–8 celled, rarely more. Sheath firm, hyaline to dark orange, conspicuous, rarely lamellate, smooth to slightly granulated. Cells spherical to hemispherical, (2.8)3.2–3.9(4.2) µm diam. Cell content homogenous to sparsely granulated, blue-green. Spores not observed.

Habitat: —Tree bark and dry rocks.

Notes: —This species differs from Gloeocapsa rupicola Kützing (1849: 221) by the pattern of colonial coloration, which is dark reddish in the inner part and almost hyaline at the edge of the colonies (Komárek & Anagnostidis 1998). The cell diameter is also smaller in G. rupicola.
