The specimens I have referred to this species ramify abund- 

 antly from their very base, which in this species consists of 

 only one cell, as well known. The branches are mostly oppo- 

 site, but scattered branches are not uncommon. The thickness 

 varies from 6 — 7//. The cells are generally longer than broad, 

 up to more than two times as long as broad. 



Epiphytically on Rhodomela lycopodioides gathered in Sep- 

 tember with a few sporangia and long hairs.
