I agree with M, those look like split-gill-
Schizophyllum commune. This is a species complex that is found throughout the world. I've seen it on cherry trees and logs- it might even be parasitic on cherry and other fruit trees. Although some people use this mushroom for food or medicine, it can be a human pathogen that can cause respiratory illness if the spores are inhaled:

I advise caution- in fact, I would not bring any specimens indoors or near your garden or orchard.
