<P> Choice of substrate varies by species as well . Moss species can be classed as growing on : rocks , exposed mineral soil , disturbed soils , acid soil , calcareous soil , cliff seeps and waterfall spray areas , streamsides , shaded humusy soil , downed logs , burnt stumps , tree trunk bases , upper tree trunks , and tree branches or in bogs . Moss species growing on or under trees are often specific about the species of trees they grow on , such as preferring conifers to broadleaf trees , oaks to alders , or vice versa . While mosses often grow on trees as epiphytes , they are never parasitic on the tree . </P>
