Sphagnum molle in general aspect resembles S. molluscum. The two differ however as follows:—the chlorophyllose cells of the ramuline leaves of both species are triangular in crosssection: in the first they are situated at the concave, and in the second at the convex surface of the leaf. Furthermore, there is a striking difference in their perichsetial leaves; those of S. molle being entirely destitute of fibrillæ, and, in their lower half, composed wholly of homomorphous cells.
