Can someone please help

me id this please it’s on a large oak that’s had a council haircut  due to proximity to playing Feilds . Thinking there’s only a few yellow ones , and I don’t think it’s yellow jelly/ or chicken of the woods . Or yellow brain but it’s young and that’s where my problem sussing it lies . 
any help much appreciated cheers rooter

Looks a lot like Inonotus dryadaeus (or is it Pseudoinonotus?)

Yes you nailed it , the juice it extrudes makes it a definite compared to a mature one . Many thanks .
