Monographs Details: Endospora bicoccus N.L.Gardner
Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Description:Species Description - Cells existing singly or in pairs, very rarely in fours, free among other algae, not forming a stratum; single cells irregular in size and form, spherical to ovoid, 2.5-3.8 µ diam., becoming ellipsoidal before division; colonies of two or four 7.2-8.4 µ diam.; walls pinkish or brick red; resting spores rounded, walls conspicuous and smooth.
Distribution and Ecology - Growing on soil by the road to Monte Montoro, Maricao, no. 1071 d, type, and no. 1077 e.
PLATE 5, FIGURE 52
A very large majority of the colonies in the above species contain only two cells. When the resting spores are forming, the appearance is that of the ordinary cell-division of Synechococcus, and were it not for the presence of a distinct cell-wall and the fact that some of the colonies came to the four-celled stage by divisions in two planes, it might be placed in that genus. It is not quite typical of the genus Endospora, which forms more complex colonies by divisions in three planes, but it forms resting spores after the manner of that genus.
