Bracket on Walnut

[Ben Y]

Hi all, hoping someone can help identify this bracket. Has been on a walnut for a good few years, grows yearly according to client. Tree in good condition, stem solid.

Can’t seem to identify it, hoping someone here may know!

Thanks, I know it’s not the best photo.

A slice of the bracket to show flesh and tube colour would help with identification, also an idea of spore colour is useful. Worth considering Rigidoporus ulmarius and Perenniporia fraxinea
