P M r have mentioned p. 1 x63 that this Conferva often grows
on Fucus lycopodhides. From the fame gentlemen to whom
we are obliged for that communication, we have received full-
grown fpecimens on the Hem of the great F. digitatus. It is
not a rare fpecies, being found, either growing or caft up, on
the coaft of various parts of Britain.
Its colour, naturally a fine red, is foon changed to a pale or
fandy hue by expofure on the beach, efpecially in the older
branches. The fronds are numerous, very much and alternately
branched, (lender, thread-fhaped, very clofely jointed throughout,
their ultimate branches briftle-fliaped and a little incurved.
The joints are deep red ; the interfiles pale, as ufual in other
fpecies. The capfules, full of dark red feeds, ftand fefiile and
folitary upon the tides of the fmaller branches.
