Found on a tree trunk at Imperial Landing (former Britannia Shipyard) in Richmond. Seems like 3 different ones. Size range from 4 to 8 cm.
Greetings David - I hope your fall has gone well! The first two look like aged oysters, not sure which kind ... but the staining suggests age rather than a different spore deposit colour. The third one has scales that are more Pholiota-like, but the overall colouring is more Gymnopilus-like. Was it alone or were there clusters? Spore deposit colour evidence is hard to assess in photos sometimes.
Thanks very much, Mr Frog. The third one is solitary, that at a distance, I at first it an orange peel !
