Who: Martin Livezey (MLivezey)

No specimen available

Old conk on Oak (or Ash?) in limestone based soils near sink-hole. White underside and margin do not seem typical of Phellinus – maybe more like Fomitopsis. Whatever killed the polypores did not seem to kill the tree. Although before leaf-out, the tree appeared to be healthy, no polypores less than 3 years old in sight.

A few megaloma specimes somewhere. Cross section should look similar to the non laccate ganodermas like applanatum.

I am very interested in this conversation.

I did not section as it was old and looked like it belonged there. No better photos or specimen available.

Indeed ive seen megaloma. I agree it could be megaloma i just wanted to err on the side of caution since the picture wasnt up close and detailed how i like.

It could be megaloma. Would need to see the flesh inside. With no up close shot and algae it is hard to determine. Megaloma is more common. Better shots and interior of flesh will remove all doubt.
