10. C. dissiliens, Dillw. (fragile Conferva); filaments elongated
straight very fragile slimy and gelatinous forming brightgreen
floating masses, articulations half as long as broad.
Dillw. Conf L 63, (not of E. Bot.) Ag. Syst. Alg. p. 90.
In streams and ditches, not uncommon.—Articulations marked by a
green band, often separating pnd adhering at the angles.
11. C. capillaris, Linn, (capillary Conferva); filaments palegreen
void of lubricity much curled and interwoven into subrigid
extensive strata, articulations 3—4 times longer than
broad.— C. crispa, Dillw. Syn. Conf p. 46. t. B— Prolifera
crispa, Vaucher Conferva capillaris, E. Bot. t. 2364.
In streams and rivulets, in many places ; forming extensive strata,
many feet in diameter. In drying, the articulations are often, but not
invariably, alternately compressed. It does not adhere to paper.
c. filaments forming crisped, entangled strata, green—growing in
the sea or in salt-water ditches.
12. C. Linum, Roth, (flax-lihe Conferva); filaments thick
rigid crisped forming loose extensive bundles of a dull-green
colour, articulations once and a half as long as broad.
Alg. p. 97. (according to specimens from that author,)
Ag. Syst.
In salt-water ditches, along the muddy sea-shore.—" Forming distinct,
loosely interwoven, subcylindrical tufts, of a yellowish-green
colour, which, in a more advanced state, changes to a dark olive :
attached at one end and resting on the bottom of the pool. Filaments
as thick as those of C. area, rigid, brittle and variously curved. Arti-
culations filled with green matter, intermixed with large granules, irregularly
contracted and compressed in drying." Carm. MSS.
13. C. crdsm, Ag. (thick Conferva); filaments very thick of
great length deep glossy-green much crisped rigid forming
loosely entangled harsh masses, articulations as long as broad.
—Ag. Syst. Alg. p. 99.— C. capillaris, Dillw. Conf. I. 9.
In salt-water ditches, near the coast, in many places: very abundant
in the ditches by the North Wall, Dublin, W. H. Harvey— Filaments
many feet long, twice as thick as hog's bristles, remarkably rigid and fra-
gile when recent ; but soon becoming flaccid on exposure to the air.
14. C. tortuosa, Dillw. (twisted Conferva); filaments rigid
slender much curled and twisted forming broad closely entangled
strata, articulations 2—3 times longer than broad.
Dillw. Conf. t. 46. Ag. Syst. Alg. p. 98.
In salt-water pools, and on marine rorks ;
abundant.
15. C. implexa, Dillw. (interwoven Coiferva); filaments very
slender capillary rather flaccid forming extensive much entangled
bright-green strata, articulations rather longer than broad.
