“ Plant bright red, at first appearing as a minute reddish stain, finally 
clothing the invested plant with a continuous downy covering. Fila- 
ments creeping and interlacing at base, and surrounding the plant on 
which it grows, much branched. Branches not attenuated, alternate, 
erect, elongated ; joints very long, often twelve times as long as broad, 
and filled with pink, slightly granular endochrome. Capsules clavate or 
obovate, alternate or opposite, sometimes, though rarely, opposite a
