Butter Bolete
Edible 
Autumn

A great and usually large mushroom, almost as good as the Penny Bun with a firm texture.

Cap
Rusty to red brown or sometimes lighter, often irregular, sometimes has a ‘cracked’ skin especially near the centre.
Pores
Lemon yellow, tight sponge like pores that darken a bit with age. These will bruise to a blue colour.
Stem
Straight or clavate, club shaped, lemon yellow at the top with yellow reticulation, (a mesh or net like covering) then usually a change to a pale orange to red towards the base.
Flesh
White to pale yellow. Turning blue when cut, the base bruising rusty brown.
Habitat
Mainly around Oak but will grow with other deciduous trees.
Possible Confusion
Other Boletes. Although the Oak Bolete is quite distinctive care should be taken when trying to identify this mushroom as it breaks the simple edible rules for Boletes (if a bolete has red on it anywhere, do not eat it and if it stains blue when cut, again, don’t eat it).

Olivaceous/brown. Subfusiform.

Excellent.

Believed to have found one last week.
Am in the process of drying it.(sliced)
Please only eat them if you are 100% sure that you have a Butter Bolete.
