Hab. Shady woods, on decayed logs, roots of trees, &c. Common, but seldom in fruit.
This species closely resembles the common European C. dendroides, which is a native also of this country. In C. Americanum the capsules are cylindrical, narrower, and much longer, with longer-rostrate opercula: the teeth of the peristone are differently shaped, being suddenly subulate from a short lanceolate base (not well represented in the figure): the leaves of the branches are more plicate, and the auricles at their base are much larger; so that a leaf, when flattened, presents a somewhat hastate outline.
