especially below, flaccid, yellowish-olive, becoming darker with
age. Paraphyses collected in little patches sunk in. the more
compact portion of the substance of the frond, clavate, scarcely
at all moniliform.
The question as to the title of the present Alga to rank as a
species has been set at rest by the discovery, by Signor Me-
neghini, of the fructification, which consists of pyriform spores
as in the common Chorda Filum. He also figures the paraphyses
as combined two or three together at the base, which
confirms Dr. Greville’s observation. I am not aware that
fructification has yet been found in Chorda tomentosa, which
appears to be equally entitled to rank as a species ; but it will
probably reward researches directed especially to its discovery.
