Fungi Id please

I saw a sycamore today (55cm dbh) with a 20cm wide cavity at the base. The cavity is about 25cm deep to the back of the tree and 25cm wide. I took some photos of the inside of the hole and found this.

 

I’ve got some thoughts but would like a second opinion on it. Any thinkers?

Rigidoporus ulmarius ould be a guess

 

Any slices taken to show the flesh and pore layer?

Sadly not, it was too high up the cavity and too small an access I couldn’t reach it.
