is no.188974, Herbarium, university of California, from
Lamds End.
In the month of December,1913, while collecting algae
in the vicinity of Pacific Grove, California, I came across
extensive areas of rock at Cypress point covered with a more
or less continuous layer of a red alga of the appearance of
Hildebrandtia. A portion of the rock ledge there is composed
of decaying granite and it was easy to remove specimens hav-
ing a granular appearance. It was found that the plant had
completely invested particles of granite that had become
loosened, and the roughened appearance of the surface was
due to those small inclosed particles rather than to cysto-
carps which I had hoped to find.
