Derscr. Root discoid. Fronds 6-12 inches high, cylindrical, filiform, much 
branched. Main stem from half a line to a line in diameter below, gradually 
attenuated upwards, undivided, or variously cleft, or subdichotomous, beset 
with very numerous, quadrifarious, lateral branches. Branches alternate, or 
issuing irregularly, very various in length, simple, or slightly divided, bearing 
a second or third set of similar but shorter and more slender branchlets ; 
which, including all the younger parts of the frond, are beset on all sides 
with minute, slender ramuli, tapering to each end, and 1-2 lines in length. 
The stem and branches are solid, composed internally of very large, hyaline, 
polygonal, cells, surrounded by others of small size, and a periphery com- 
posed of minute cellules. The large interior cells, seen through the coat of 
the frond, give the surface, under a low power of the microscope, a reticu- 
lated appearance. The ramuli consist of whorls of horizontal, radiating, 
dichotomous, jointed filaments, closely packed together, and issuing from a 
slender, cellular axis. When in fructification, the ramuli become wider in 
the middle, taking a spindle shape, and spores of an oblong, pyriform shape, 
are formed at the bases of the whorled filaments. The colour is.a brilliant, 
rose-red, the sudstance gelatinoso-membranaceous, and the plant adheres to 
paper in drying.
