Herposiphonia secunda   (C. Agardh) Ambronn,  1880 (Algae)
Organism information awaits expert curation
Class: Florideophyceae

Color: Dark reddish-brown throughout, the cell membranes often yellowish-brown.

Thallus prostrate, entangled, finely fibrous mats tightly adhering to substratum. Plants small, usually about 1-2 cm diameter, closely attached to the substratum, sometimes forming close mats or entangled upon and attached to masses of other algae. Branching of the main axes irregularly alternate, the apices strongly curved toward the older axes nearly straight, 75-150 µ diameter, with 7-8 pericentral cells. Axes with an indeterminate branch or a rudiment of one usually preceding each branchlet, these originating every fifth or sixth node and to 60-70 µ diameter with 7-8 pericentral cells. Pericarps solitary near the summits of the branchlets, displacing the apex. Rhizoids single celled, occasionally with finger-like, branched apices.
