“Hi Simon, we would strongly advise against eating any fungi that you find. This looks like a Honey fungus but it’s difficult to be 100% sure from just one photo!”

“Honey Fungus (Armillaria mellea)
Honey Fungus is the common name given to several species of the fungus Armillaria.
It is the most destructive fungus in UK gardens, known for attacking and killing roots of many woody plants.
In autumn, clumps of honey-coloured mushrooms (which are a type of reproductive structure) appear at the base of infected tree stumps. Unfortunately, there is no effective way to cure these trees; the only solution is to remove and destroy all infected root and stump material.”
