Crouan, but, as it is not in the extensive collections distributed
by M. Lenormand, it is probably a rare species. It should be
observed too, that in the plant from Brest the articulations of
the fertile pinnae are longer than in specimens from the opposite
side of the Channel, and that the tetraspores are by no
means confined to the pinnae.
Forming globose rose-red or purplish tufts, from 1-3 inches
long, much-branched, adorned above with alternate oblong
plumules, whose subulate pinnae are alternate with articulations
scarcely twice as long as broad, and bearing on their
upper side a row of obovate or elliptic tetraspores. Ultimate
plumules subfastigiate. The favilliferous individuals are far
less regular. Favillae large, globose. We are indebted for
our specimens to Mr. Ralfs.—M. J. B.
