Anatheca -"arcata. sp. nov.

Setchell & O-ardner, Univ. California
Publ. Bot. 1:310. Pi. 23,	31 Mr. 1903.

Frond arising from a discoid holdfast, cylindrical below (for
1-2 cm.), flattened above, and expanding upward to a length of 20 cm.
and a breadth of 2-3 cm., once to thrice forked; nib stance thick; and
firm; color dark re&; frond possessing a medullary tissue of fine
longitudinal hyphal cells, inner cortex of large cells which sudden-
ly become shaller in the outer cortex, while the epidermis is of
small, regular, slightly palisade-like cells. Cystocarps scattered
over the surfaces of the frond, prominent, hemispherical, with apical
carpostome. The placenta is central and composed of large cells; th«
spores are in groups radiating from the placenta on all sides, and
are separated from one another by strands of medullary tissue. Tet-
rasporangia scattered in the outer cortex, zonately divided.

Cast ashore from deep water, West coast of Whidbey Island, Waslr

This species might be taken for Oallophyllls furcata f. typica
at first glance, so great is the resemblance in habit, color, size,
etc. It seems probably a member of the genus Anatheca, and very
closely related to the type, A. Monta.-mei Schmitz, from the coast of
Senegambia. We have been unable to examine the type specimen, but
the chief difference seems to be the more distinctly serrated margin
of the Senegambian plant. Schmitz says (lR96-lR97, p. 3?4) that the
spores are terminal on the sooriferous filaments. They are so situ-
ated in young specimens o^ our plant, but, in mature cystocarps,
they are seriate.
