Family V. CHORDARIACEJE. Har. 
Olive colored, gelatinous or cartilaginous, composed of vertical and horizontal 
filaments interlaced together ; spores attached to the filaments, concealed within the 
substance. 
Genus, CHORDARXA. A g. 
Cartilagenous, filiform, much branched; the axis composed of densely packed, 
longitudinal, interlaced cylindrical filaments; the periphery of simple, club-shaped, 
horizontal, whorled filaments, and long capilary, gelatinous fibres. Fructification ; 
obovate spores, seated among the filaments of the periphery. 
No. 30. C. flagelliformis. Mull. Filiform equal throughout, branches alter¬ 
nate, mostly simple ; filaments of the periphery club shape.— -Grev. 
From 3 to 12 inches long, found only at Hurlgate at low water mark, rare. 
Genus, ELACHISTEA. Fries. 
Parasitical, a dense tuft of free, simple, articulated, olivaceous filaments, rising 
from a common tubercular base; fructification, pear-shape spores attached to the 
bases of the filaments, concealed in the tubercle.— Ilarv. 
No. 33. E. fucicola . Yelley. Tufts pencilled, rusty brown, membranaceous, 
articulations once or twice as long as broad; fruit hemispherical. 
Summer, parasitical on Fucus and other Algae, rare in our harbor, occasionally found floating ; is very 
abundant in the Sound, a few miles eastward; it is rather rigid, dichotomous, and irregularly branched; 
some of the ultimate ramuli are quadriferous, or spreading on all sides. 
Note —We have in our waters several species anrl genera of this family, that are almost or entirely microscopic, and therefore not suited 
to this work, and which require more critical examinations than I can at present bestow. 
Family VI. RCTOCARPEJE. Ag. 
Filiform, olive-colored, articulated, whose spores are generally external, attach¬ 
ed to the ramuli. 
Genus, SPIIACELARIA. Lyng. 
Filaments rigid, jointed, distichously branched, rarely subdichotomous ; apices 
of branches distended, membraneous. Fructification, oval spores on the ramuli. 
No. 35. S. cirrhosa. Roth. Filaments naked at base, branched, jointed, pin¬ 
nae opposite, alternate, or irregular. 
At Hurlgate, on Fucus vesiculosus and F. nodosus; summer, half an inch to 1 or 2 inches, densely 
tufted. 
No. 36. S. plumosa. Lyng. Filaments naked at base, elongated, irregularly 
branched, inarticulate, pinnae opposite, simple, very close, elongated. 
Autumn, on F. vesiculosus and other Algae near low water mark, at Hurlgate, Castle Garden, and else¬ 
where ; half inch to 2 inches long.
