Epiphytic mosses and liverworts contribute substantially to the bryophyte diversity of circumpolar boreal forests but are susceptible lo altered growing conditions after forest harvesting.

Ulota species are difficult to separate to species level on leaf characters alone. In this study, scanning electron microscopy of habit and leaves, capsules, peristomes, and spores proved useful in separating four Australian species. Details of capsule and peristome, particularly distinctive features of the endostome, are shown.
