Scapania cuspiduligera, like most of the Scapaniaceae, has complicate-bilobed leaves with a dorsal (upper) lobe that is smaller than the ventral (bottom) lobe. The ventral leaf lobes are decurrent and the dorsal leaf lobes are upturned. There are no underleaves. In general the plants are small and pale yellowish. The leaves are bordered with a row of thick walled cells. There are frequent clusters of red brown gemmae near the shoot apices. Thanks to John Brinda for confirming the ID of this liverwort!
