Coilodesme corrugata S. and G.
Santa Catalina Island, Calif.

March 1913

U. L. Gardner. Ho. 2584. Co-type

3. Coilodesme corrugata S. and G.

Plate 46, figs. 3, 4

Fronds very fragile and flaccid, very closely wrinkled all over the
surface, 3-7 cm. long, 8-14 mm. broad, 40-55/i, thick, attached to the
host by (penetrating?) rhizoidal filaments, rounded above, attenuated
below into a short delicate stipe; color light brown; internal tissue
composed of 2 layers of large, irregular, colorless cells and the cortical
tissue composed of 2-3 layers of small, angular cells; zoosporangia
irregular in form, usually broader than long.

Epiphytic upon Cystoseira neglecta S. ancl G. In the upper sub-
littoral belt. Santa Catalina Island, southern California.

Setchell and Gardner, Phyc. Cont., VII, 1924, p. 8.

This is the smallest and most delicate species of the genus, and
seems related to C. amplissima in general outline and structure. These
characters, together with the delicate wrinkling and its occurrence on
a distinct and not common host, lead us to keep it distinct. Appar-
ently it is quite limited in its distribution.
