“ The tufts are dense, soft, and woolly, not gelatinous, and adhere but 
imperfectly to paper; they are often confluent, their colour is reddish, 
becoming tawny by age, andindrying. Filaments much branched, main 
branches elongated, somewhat level-topped, fructiferous branches lateral, 
numerous, short,'patent, much divided. Capsules at first oval or clavate, 
finally orbicular, crowded in a corymbose manner, mostly stalked. 
Joints of stem 3-5 times as long as broad, those of fertile branches 
shorter. Differs from C. chalybea in colour, and in its shorter joints and 
more patent ramuli.”—Ralfs.
