at the base into a slender short stipe; color dark reddish brown, espe-
cially so on drying, internal tissue of 2 layers of large cells, cortex of
2-3 layers of smaller cells, radially elongated, both tissues bearing
chromatophores.

Growing on Cystophyllum gemmatum (Ag.) J. Ag. Sitka, Alaska.

Setehell and Gardner, Phyc. Cont., VII, 1924, p. 9.

Coilodesme sitchensis occurs on the same host as C. linearis and
C. californica. From the former it is to be distinguished by its broader
and more bullose habit and from both by its longer and more definite
stipe. It is also darker in color than C. californica and rather more
bullose and undulated on the margins after collapsing. It may be
this species which was reported by Saunders on “Cystophyllum
Lepidium” in localities north of the Puget Sound region.
