Not sure what they are but boy are they cool looking! :) They look like little stairs up the tree :) Awesome POV and colors in these as well :) Well done darling :)
Polypores. Mushrooms that bracket or shelf on the side of a tree. I seem to remember that they can be not good for a tree. You have captured them well!
Great capture of fungai clad tree with the snow. The tonal qualities look stunning !
