Chroococcus mediocris sp. nov.

Plate 2, figure 14

Families composed of 2-4 cells, free, not forming a definite
stratum alone; single cells spherical, bright aeruginous, finely
granular; families of 4 very angular, 9-11.5 m diam. without
tegument, 15-18 p diam. with the tegument; tegument hyaline,
homogeneous, smooth.

Growing in association with numerous other species of algae
in Laguna Tortuguero, no. 831 h, type.

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.
