Last week's Guess What is difficult (as far as I am concerned) to name accurately. It is a type of polypore or bracket fungus which I found growing on an old tree stump in the garden......
..... so I think a is deserved by Andrew, Adrian, Glo, Keith and Wilma for their suggestions.
This week's mystery photo should be much easier to identify.
No prizes, just for fun.
