CHONDRIA RUBRA, Zar. 
Gun. Cuar. Frond filiform, cartilagineous, dendroid, opaque, coated with 
small, polygonal, irregularly-placed cells. wis articulated, polysi- 
phonous. Ramuli claveform, much constricted at their insertion. 
Fructification: 1, ovate ceramidia ; 2, tripartite ¢etraspores, formed 
irregularly, in the clavate ramulii—Cuonpria (4y.), yovdpos, car- 
tilage. 
Frons filiformis, cartilaginea, dendroidea, opaca, cellulis irregularibus polygonis 
corticata. Axis articulatus, polysiphonus. Ramuli clavati, basi constricti. 
Fruct.: 1, ceramidia ovata ; 2, tetraspore triangule divise, in ramulis im- 
mers, sparse v. wregulariter aggregate. 
Cuonpria rubra; dendroid, robust, rigid, blood-red; frond irregularly 
decompound, much branched, the branches scattered, spreading to all 
sides, gradually attenuated ; ramuli linear-fusiform, acute, narrowed to 
the base ; ceramidia ovate, sessile on the sides of the ramuli. 
Ch. rubra ; dendroidea, robusta, rigida, sanguinea ; fronde vage decomposita ramo- 
sissima ; Tamis sparsis quoquoversum egredientibus sensim attenuatis ; ramulis 
lineari-fusiformibus acutis basi angustatis ; ceramidiis ovatis ad latera ramu- 
lorum sessilibus.

Geoer. Distr. 
Descr. Root unknown. Stem 6-8 inches long (or probably much longer), 15 
lines in diameter at base, tapering much to the summit, either simple or 
once or twice forked, the main divisions closely set with alternate or scat- 
tered branches. ranches spreading every way, repeatedly divided in an 
irregular manner, each set more slender than the preceding, the lesser ones 
mostly alternately divided. Ramuli scattered, erect, filiform, but slightly 
narrowed at base, acute, 3-5 lines long. The stem and larger branches are 
perfectly opaque, the smaller branches and ramuli, under a lens, are marked 
with transverse striz (as in Rytiphlea), at distances about equal to the di- 
ameter of the part. These disappear under the microscope; they are caused 
by the cells of the articulated 5-tubed axis, seen through the cortical layer. 
Ceramidia ovate, sessile on the ramuli, with thick walls and a narrow, hya- 
line limbus; spores small. etraspores unknown. Colour a bright blood- 
red, turning darker (and blackish in the stems) in drying. Sudstance rather 
rigid. In drying it adheres very imperfectly to paper.
