mucilaginous colonies

spherical/elliptical mucilage sheaths
(a) with flagella or pseudocilia
(i) pseudocilia (non-motile hair-like appendages)
Apiocystis brauniana FAFBI p. 299 plate 76	Cells around the periphery of a sac-like mucilaginous envelope, attached at one end. Pseudocilia project through the mucilage
Tetraspora FAFBI p. 303 plate 76
(ii) flagella: motile appendages which make the colony motile
Eudorina FAFBI p. 317 plate 81	each cell has a pair of flagella; cells spaced out from each other
Pandorina FAFBI p. 320 plate 81	each cell has a pair of flagella; cells tightly packed together; angular from mutual compression	(Lugol's)
(b) without flagella or pseudocilia
(i) *Cyanobacteria: cells with chlorophyll not enclosed in a chloroplast (not always easy to see)*
Coelosphaerium FAFBI p.42 plate 5	Colony spherical or subspherical, the cells grouped around the outside forming a hollow ball
Woronichinia FAFBI p.58 plate 5	Similar to Coelosphaerium but cells are somewhat elongate, at the end of radiating stalks
Snowella FAFBI p.56 plate 4
Chroococcus FAFBI p.40 plate 3	Cells in pairs or multiples of 2, somewhat flattened where the cells are in close contact (sometimes with concentrically striated mucilage).
			C. limneticus
Eucapsis FAFBI p.45 plate 5	Cells in groups of multiples of 4 in more or less cubical arrangement
Merismopedia FAFBI p.51 plate 3	Cells in groups of 4 or multiples of 4, forming a flat (or sometimes rolled) plate.
Nostoc FAFBI p.105 plate 18	Clusters of filaments in a firm mucilaginous envelope. The cells are spherical with occasional heterocysts (rather similar to Anabaena)

(ii) cells with chloroplasts, in groups within a concentrically layered mucilage
?Gloeocystis FAFBI p. 356 plate 86

Asterococcus FAFBI p.299 plate 76	Cells spherical or subspherical, with stellate chloroplast. Mucilage envelope wider than cell.

	Non-lamellate mucilage, cells 10-25µm = A. limneticus
	Lamellate mucilage, cells 30-43µm = A. superbus
