Can cause excitement when first found due to thinking you have found a Penny Bun and although this mushroom is technically edible if it is mistakenly added to a meal it will ruin it and render it too bitter for consumption.

Please note that each and every mushroom you come across may vary in appearance to these photos.
Cap
7-10 cm. Pale to dark brown. Starting convex with a suede like covering but flattening out, losing any small hairs and sometimes splitting with age.
Pores
Starts with white, sponge like pores that develop a pink tinge around the pore openings and will bruise pink when damaged eventually turning brown.
Stem
7-10 cm long, 2-3 cm diameter. Off white to tan with a darker net like pattern or reticulation, particularly towards the top of the stem. The base is usually wider than the top.
Flesh
White and unchanging sometimes with a pink flush.
Habitat
Mixed woodland, more often with broadleaf trees but will grow with coniferous trees.
Possible Confusion
Can look very like a Penny Bun (Boletus edulis), pictured, or Summer Bolete (Boletus reticulatus) but the reticulation on the stem is dark on a lighter background for the Bitter Bolete and light on a slightly darker background for the Penny Bun and Summer Bolete and the pores of the Penny Bun and Summer Bolete do not bruise to a pink colour like the Bitter Bolete.
Taste / Smell
Extremely bitter.
Spores
Clay-pink to wine coloured. Subfusiform.
Other Facts
Felleus roughly translates as bile which is a good description of this mushrooms bitterness.
