Chorda tomentosa, Aresch.—Though not recorded, this species has
probably been collected in this country, but confounded with C.
filum, the spring state of which it considerably resembles. It is,
however, shorter and stouter, and has longer and denser hairs,«-which
continue till after the fruit is formed, in May and Juiie. The hairs
of C. filum fall off in the spring, while the fruit is not formed until
August. The sporangia of C. tomentosa are about double the length
of those of C. filum, and are cylindrical rather than ovate. The
former are figured in Areschoug’s Observationes Phycologicse, Part

iii.,	Tab. ii., Fig. i; the latter in Farlow’s Manual of the New Eng-
land Marine Algae, PI. vi., Fig. i. My specimens were collected i‘
June, at Nahant, Mass., where the plant seems not to be verv rare.
