Illustrations:

Sporophyte: Chen and Edelstein 1979, p. 407, fig. 1 (photo: habit), fig. 2 (photo: unilocular sporangia), figs. 6–10, 12 (photos: development in culture of sporophytes with unilocular sporangia); Scagel 1967, p. 115, figs. 43a, b (habit), fig. 43c (x-section, fertile blade); Setchell and Gardner 1925, pl. 45, fig. 77 (surface view, unilocular sporangia), fig. 78 (x-section, unilocular sporangia). Microthalli (Gametophytes?): Chen and Edelstein 1979, figs. 11–13 (photos: development in culture of microthalli bearing plurilocular organs)

Pacific Coast Distribution:

Amchitka I., Aleutian Is., Alaska (Wynne 1972a, p. 133) to Whidbey I., Wash. (Scagel 1957, p. 91); Coos Bay, Ore. (Setchell and Gardner 1925, p. 581); Pt. Cabrillo, Mendocino Co., Calif. (DeCew, HSC 10201)

Life History:

zoospores from unilocular sporangia on macroscopic sporophytes develop into prostrate filamentous microthalli that asexually produce macroscopic sporophytes; microthalli may produce plurilocular organs of unknown function (Chen and Edelstein 1979, Wynne 1972a, p. 131)
