1185. Prasiola Gardneri n. sp.
Floating in a pool of very salt water, Alameda, California,
Sept. 16, 1908.
W. J, V. OSTERHOUT & N. L. GARDNER
Fronds light green, floating, of irregular form, membrane
very delicate, about .006 mm. thick, cells roundish, .003-.004 mm.
diam., closely set, in longitudinal and transverse series.
As this plant has been found only floating, nothing is known
of the normal form or mode of attachment. The cells being uni-
formly placed, without the “passage ways” characteristic of
Prasiola, the plant might with some reason be placed in Monos-
troma; and when the attached frond is found, it may have char-
acters requiring the transfer. In the meantime, the general
appearance seems to justify its present position.
