Phycotheca Boreali-Americana. Collins, Holden, and Setchell«
664, Ghaetomorpha Galifornica Collins ms.
Growing on sand, etc., in shallow tide pools near high water mark,
La Jolla, San Diego County, California, May^ 1898.
MRS. E. SNYDER.
Filaments attached, erect, up to 2 dm. long, of uniform diameter
throughout, not contracted at the nodes; diameter .02-.04 mm., cells once
to twice as long as broad, rarely three or four times as long; basal cell
usually colorless, slightly broadening below into a colorless disk of
attachment.
In view of the large number of described species of Chaetomorpha,
many known only from the descriptions, it may seem rash to add one more;
but the plant now in question is much more slender than any other known
attached erect species ; an examination of a large suite of specimens shows
that while a considerable range of size can be seen in the same tuft, in no
ca®e does the diameter exceed .04 mm., while the average is .03 mm.,
about half the size of the smallest heretofore known.
