A mushroom/toadstool with a flat cap, darkish centre and a ‘daisy’ appearance ie large petals. What is it?

Question

I grows where a very large and old ‘fir’ tree was removed on sawdust covered ground.

Answer 1

Your photo did not come through. Mushrooms are hard to identify, even with a microscope. Many mushrooms dry and crack like you describe. It will be nearly impossible to determine what it is without clear detailed photos of the mushroom (all parts) the area it was found in, and a photo of the spore print.
