Aphanothece cf. microscopica Nägeli (1849: 59) ( Figs. 1H–1I ).

Round colonies, 24.6–77.8 µm diam., sub-colonies often present, 8.0–12.7 µm diam. Sheath firm, hyaline, conspicuous. Cells sparsely to densely disposed, cylindrical, rarely ellipsoid, 3.1–6.0(7.2) × 1.7–2.9 µm, 1.8–2.0 times longer than wide. Cell content slightly granulated, intense blue-green.

Habitat: —Waterlogged soil covered by vegetation.

Notes: —The studied specimens have a cell length smaller than what is proposed by Komárek & Anagnostidis (1998). Furthermore, the habitat of Aphanothece microscopica is a little different (moorland freshwater). However, Desikachary (1959) reported the occurrence of A. microscopica in waterlogged soils from India, and Wille (1914) found this species among mosses.

Studied material: — BRAZIL. São Paulo: Cananéia, State Park of “Ilha do Cardoso” ( Perequê ), 25º 4’ 8” S, 47º 55’ 12.24” W, 29 June 2010, W.A. Gama-Jr. & C.F.S. Malone (SP 401439) .
