What side of the tree does moss grow on?

Yes, moss does begins a very, very large part of its life cycle only on the north side of trees in the US. However, after a very, very long time that the moss has established itself, I'm talking decades here, then the moss will take over the south side too. But not initially and it rarely lasts that long to take over both sides of a tree. It generally will perish first.

Moss grows on all sides of trees. It grows thickest on the north side because the north side doesn't get as much direct sunlight (If it gets any at all) And moss generally grows better in shaded areas.

If this is true that moss grows thickest on the north side of the tree, in the Southern Hemisphere the moss should then grow on the south side of the tree as the sun should pretty much always face the north side of the tree on trees below the equator.
