Fungus growing on the stump of a eucalyptus tree in shady area of garden. In evening light the fungus had a much darker and silvery sheen. Another stump also had the same fungus at the same time, the cycle was over in 3 to 4 days. I don't know much about fungi but can't find any id either. Interested in any comments.
