Hab. In dry woods, on decayed logs, roots of trees, and the ground.—Very common.
C. cladorrhizans has until recently been considered a native of North America only; but the European C. Schleicheri is now admitted to be the same species slightly modified. Of the two plants, Prof. Schimper, in his excellent Synopsis Muse. Europ., says: "Stirps americana differt notis pluribus ab europæa, sed vix satis gravibus ut specie distinguatur."
