Hideaways

Miniature white mushrooms hiding in cracks in tree bark:

Pure white balls, pinhead to marble size.

These are a bit larger, and stalked. Growing under roots on a nurse stump.

Zooming in on others on the same roots. They burst through from the inner "meat" of the roots; note the broken end, where no bark impedes their growth.

These grow in clusters from bottom to top of a deep crack in the bark.

And where the bark is long gone, these side-stalked tan mushrooms force their way out.

I've tried and failed to identify these beauties.
