At first sight this species might be mistaken for a Cephalozia, but a close examination of the leaves will at once show the difference. Dr. Alexander Evans says r " A peculiar habit of the plant is the way in which its prostrate stems creep over tufts of mosses and other hepatics, the tufts thus encroached upon are in time completely covered by the Lepidozia, and, as their supply of light is cut off, they become feeble and finally perish. It is among these crowded patches, and particu- larly those which grow on rotten logs, that we must look for fruiting specimens, the plants on shaded rocks being almost in- variably feebly developed and ; L,.

CEPHALOZIA. According to Dr. Evans we have eleven species of Cephalozia in New England. The Cephalozias, however, are so tiny that it is difficult to recognize the species with a lens, al- though the genus can readily be made out by reason of the small size and peculiar rounded two-lobed leaves which in some species remind one of tiny lobster claws. One or more of these beautiful tiny plants can be collected on Figure 106. Branch of ^very trip if one takes the trouble to Cephalozia bicuspidata X 2 look for them. They grow on bare at the left.
