Abstract: The spore morphology of 26 species of the family Pottiaceae was observed by light microscope and scanning electron microscope. The results showed that the spore characteristics are similar in shape, shape of the proximal face and exine ornamentation, but different in the size and exiguous structure of the ornamentation. It showed heredity similarity and differentiation among the different genus and species in Pottiaceae, and Pottiaceae may be a natural taxon.

Key words: Pottiaceae, spore morphology, ornamentation
