Discussion
PLATE 2, FIGURE 14
The species described above has a near relative, so far as size is concerned, in Chroococcus limneticus Lemm. The colonies do not adhere into a stratum and the individual tegument is thinner and is homogeneous, and there is no tegument investing groups of cells and colonies as in C. limneticus. It is also closely related to C. subsphericus of this paper.
