Description
Thallus up to 46 cm tall, terete, up to 2.3 mm broad, with 2 (4) orders of branching, microcystidiate, composed of a cortex with two layers of subquadrate cells [(4.8)-5.9-(7.2) x (4.8)-7.4-(9.6) microns] and a medulla with c. five layers of large cells in cross-section [(997)-196-(310) x (107)-224-(339) microns]. Spermatangia in confluent deep sub-cortical conceptacles, (26)-58-(132) microns in diameter to (48)-99-(178) microns deep. Cystocarps (0.9)-1.2-(1.7) mm in diameter and (0.70)-0.8-(1.1) mm high; pericarp (127)-159-(216) microns thick, with 15-17 cell layers and a prominent ostiole; gonimoblast domed, developing from a highly dissected fusion cell; tubular nutritive cells fusing with cells of the floor of the cystocarp and rarely with the outer pericarp; terminal carposporangia (19.2)-22.6- (26.4) microns in diameter. Tetrasporngia cruciately divided, (19.2)-24.7-(31.2) x (31.2)-42.1-(50.4) microns, scattered over the thallus.

Habitat
