I love mushroom photography and look forward to shooting them here in the Colorado Rockes in the next few weeks. I like the colors and textures around the mushrooms. I would crop out the OOF areas.
I agree with Joanna. You have beautiful texture and detail throughout the image...I'd hate to see it mucked up with that OOF area. If you need to, crop it to be a pano size...I think it would really set this image off!
