Timspurckia oligopyrenoides

Overview
1. Spherical cells 7–11 mm in diameter, conspicuous (2 mm thick) clear extracellular matrix, greyish red to reddish brown, exhibiting positive phototaxis.
2. The single chloroplast has numerous lobes extending from multiple pyrenoids located throughout the cell.
3. Pyrenoids, containing tubular thylakoids, are exposed to the cytoplasm and are usually surrounded by a starch sheath.
4. Starch grains also present elsewhere in cells, usually adjacent to chloroplast lobes.
5. Peripheral thylakoids absent.
6. Golgi bodies always closely associated with a mitochondrion and usually located at the cell periphery.
7. Nucleus peripheral with a single nucleolus appressed to the region of the nuclear envelope usually closest to the cell center.
8. Low molecular weight carbohydrates are floridoside, digeneaside and trehalose.
