Quercus is the genus name given to the oak trees, and oaks, especially the English oak (Quercus robur) is host to many an interesting fungi, in this case the oak maizegill (Daedalea quercina). It is not a common fungi but can be frequently found in the New forest.
It is called maizegill because the spore baring apparatus on the underside looks like a maize.
Another fungi that I found is the chicken of the woods (Laetiporus sulphureus) also called the sulphur bracket . It usually grows on oak and is one of the best edible fungi of the summertime. when young the texture, smell and flavour of it is excellent. I collected the bottom tier of this specimen.
