Abstract: Paraffin sectioning technique and scanning electron microscopy methods were applied to observe six species of masses. The internal structure of stems,leaves and the stratum corneum surface ornamentation, warts growth and micro-hole were compared.The results indicated that the epidermal cells of Rhytidium rugosum(Hedw.) Kindb. have small verrucose on outer wall, while the tandem of the wall adjacent to the surface of the cuticle cell patterns long into parallel bundles; stem axis of the Abietinella abietina(hedw.) fleisch was not obvious, in the back of a rib-like thorns protruding warts, dorsal, ventral surfaces of the side wall warts, was covered like; the epidermal cells wall of Bartramia ithphylla Brid. uplift, holes was not sink, orifice was covered by the cuticle ornamentation; the back surface of leaf crude cell wall of Aulacomnium palustre(Hedw.) Schwagr. warts highlighted by the depression, cuticle ornamentation was banded, leaf faces big belly, and in many cell wall-like interface was open; the epidermal cells of back leave of Hylocommium splendens(Hedw.) B.S.G wart like thorns wide, dorsal, ventral warts rough high, the top of the cell wall with depression; Dorsal, ventral cells irregular depressions adjacent cell wall of Ceratodon purpureus(hedw.) Brid. was a small intensive wart.
