Moss Habitats — Midland Naturalist…
“ Hence, I can only indicate the most likely mosses to be found in particular habitats. In many instances the same plants may be found flourishing in equal abundance in a variety of habitats. I have already mentioned Ceratodon purparens, as a moss to be found everywhere. It is abundant on heathy waysides and on old walls, thatched roofs, and even on trees it is no less plentiful. ”
