Found these interesting Peziza type mushrooms growing on the remains of a burnt down shed. (Slight mishap with a barbecue in the summer.) I was quite surprised, as I thought timber was usually treated with anti-fungal chemicals. Very difficult to pin down exactly what this is – there’s a few species that grow on burnt wood but they aren’t generally tan coloured. It looks more like Peziza petersii than Charcol Cup.
