Grn. Coar. laments destitute of a mucous layer, free, flexible, elongated, 
decumbent, not oscillating. Zu4e continuous; endochrome green or 
purple, densely annulated, and finally separating into lenticular 
sporidia. LiyneBya (4g.) m honour of Hans Christian Lyngbye, 
author of an excellent work on the Algee of Denmark. 
Lynepya majuscula; tufts of large size; filaments very thick, issuing in 
long, crisped bundles, from a blackish-green stratum, twisted, simple 
or shghtly pseudo-branched.

Descr. Filaments collected into widely spreading, blackish green, glossy strata, 
of several inches in diameter, which lie on the surface of flat rocks, or on 
the sands; at length rising to the surface and floating to the shore. In 
these strata the filaments are densely interwoven, and issue from the upper 
surface, and from the edges, in crisped bundles, one to two inches long. 
They are very tortuous, simple, or now and then cohering together, as if 
branched, and are of greater diameter than those of any other species of 
this genus, twice or thrice as thick as those of LZ. muralis. The endochrome 
is of dull, glaucous green; the annuli closely set; and the border of the 
tube broad and colourless. Sometimes the endochrome is interrupted at 
intervals, as if broken; and sometimes it separates as by a distinct articu- 
lation, into two portions, and it is probable that at a more advanced period 
the uppermost portion further separates from the lower, and becomes a new 
filament.

This is the largest growing, and strongest species of the genus, 
and in favourable situations becomes quite a handsome plant, 
resembling in all but colour, fine tufts of curling hair. But if 
we suppose it to have belonged to a sea nymph, the dark green 
hue is not so mappropriate.
