Anacystis gloeocapsoides sp. nov

Plate 4, figure 41

Colonies spherical, more or less associated into groups ad-
hering by their sticky walls or floating free, 15-30 ¡j diam.; cells
not densely crowded in the colony, each secreting a tegument dif-
ferentiated from the colonial tegument, 2-4 cells at times re-
maining in the special tegument for some time before its fusion
with the general tegument, pale aeruginous, 2-2.4 n diam.; rest-
ing spores only slightly changed vegetative cells; tegument lirm
and smooth on the surface, rather close-fitting, coral red, lamel-
lose throughout the colony, the special teguments usually colored
brighter than the colonial tegument.

Growing in association with other species of Myxophyceae
on rocks by Laguna Joyuda, Mayaguez, no. 1304, type.

This species of Anacystis seems closely related to Gloeocapsa
rosea Kuetz., judging from Kuetzing’s original description.
The description is, however, incomplete regarding the life his-
tory, and no specimens are available for comparison.
