Deuterostichococcus epilithicus

Pröschold and Darienko 2020 ( Fig. 2 )

Cells are usually unicellular. Under salinity stress can form unbranched filaments out of 2 - 4 cells, which are easy fragmenting. On freshwater medium, cells are cylindrical with rounded ends. Cell walls thin, without mucilaginous layer. Chloroplasts are located in the cell periphery, not lobed with smooth margin, without pyrenoid. The length of the cell is 3.8 - 8.1 μm and the width is 2.3 - 3.0 μm.

Note. This species was newly named from Stichococcus -like strains based on 18S and ITS rDNA sequences by Pröschold and Darienko (2020). The SAG 2482 strain among Deuterostichococcus epilithicus strains is morphologically similar to the NIBRCL0000114567 strain.

Ecology. This is a terrestrial species. They inhabit rock and stone walls ( Reisigl, 1964).
