Scytolyngbya timoleontis Gao-Fei Song, Yong-Guang Jiang, and Ren-Hui Li, 2015 ( Fig. 5 )

Filaments wavy or straight, entangled, attenuated at the end, yellow-brown or dark green in color. Sheath initially thin, firm or diffluent, colorless, commonly multiple trichomes in a single sheath. Trichomes constricted at cross-walls, rarely false branched in old culture. Cells longer than wide, 2.7-5.2 μm long, 1.5-2.3 μm wide. Apical cells rounded and cylindrical. Hormogonia are separated by necridic cells.

Ecology. This species was isolated on the stone surfaces of wells at a water treatment facility ( Song et al., 2015), and in this study from gravel submerged in freshwater.

Distribution. Xishui, Hubei, China ( Song et al., 2015).

Site of collection. Site 6.

Specimen locality: ACKU677.

Order Oculatellales Strunecký and Mareš, 2023 Family Oculatellaceae Mai and J.R.Johansen, 2018 Genus Shackletoniella (W.West and G.S.West) Strunecký, Raabová, and Bernardova, 2020
