Boletus edulis · Boletaceae

Edible

The most sought-after wild mushroom in Britain: nutty, firm and richly scented, with a pale bun-like cap and a fat netted stem.

Edible. No deadly lookalikes in Britain, but always check that the pores are white to olive and never red or orange.

  • Conifer woodland
  • Woodland edges

Identification

Cap
6-25cm, pale to chestnut brown, smooth and slightly greasy when damp, often with a fine white rim when young.
Gills / pores
No gills. Underside is a sponge of tiny tubes, white when young, turning yellow then olive with age.
Stem
Very stout and barrel-shaped, cream to pale brown, with a fine white raised net over the upper half.
Flesh
White, firm, unchanging when cut.
Spore print
Olive brown.
Smell & taste
Pleasantly nutty and mushroomy; taste mild.

Lookalikes

Bitter Bolete (Tylopilus felleus) has a dark net on the stem and pinkish pores, and is unbearably bitter. Devils Bolete has red pores.

In the kitchen

Superb fresh in butter, and the best of all mushrooms for drying. Slice thinly and check for maggots before cooking.

Recipes using Penny Bun

  • Wild Mushrooms on Toast

    The honest test of any wild mushroom. Butter, a hot pan, good bread and nothing to hide behind.

  • Cep and Thyme Risotto

    Dried ceps do most of the work here. The soaking liquid is the real ingredient.

  • Wild Mushroom Powder

    The best way to use a glut, and the most useful jar in the kitchen.

  • Cheat's wild mushroom risotto

    The original oven-baked risotto from the old Wild Mushrooms Online recipe pages. No standing over the pan stirring for half an hour - the oven does the work while you lay the table. Dried ceps give the depth, fresh wild mushrooms give the texture.

  • Rich wild woodland mushroom soup

    A thick, dark, thoroughly old-fashioned soup thickened with stale bread rather than flour. It was written for a big autumn haul of mixed woodland mushrooms and it is still the best way to use a basket of odds and ends.

    Curved blade with a boar bristle brush in the handle. The standard foraging knife for good reason.
