Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Description:Species Description - Filaments short and tortuous, not forming a definite stratum, 7-8.5 µ diam.; trichomes 5.6-7.2 µ diam., not constricted at the dissepiments; apices very slightly attenuated; cells 1-1.4 µ long, contents homogeneous, pale aeruginous; cell walls very thin but distinct; terminal cell capitate, sheath at first hyaline and homogeneous, later becoming thicker and dense, becoming yellowish and finally dark brown, in part lamellose and decidedly ocreate.

Distribution and Ecology - Growing on damp earth by Playa, Fajardo, no. 710 c, type.



The material of this species was found associated with several species of Myxophyceae. The soil on which it grew is said by Wille to be ''brackish," but no further comment was given. The crooked filaments with brown ocreate sheaths remind one at first of the genus Scytonema, but it has neither heterocysts nor branching. The trichomes appear to have had several periods of growth. At times they extend entirely beyond the parent sheath, and are naked. Another region may have a hyaline sheath, another farther back may be decidedly colored and ocreate, the oldest part of which may be considerably thickened. Apparently the species is not abundant and not widely distributed.
