Most people don't pick this mushroom, since it has the red pores which are normally associated with the (possibly deadly) poisonous Boletus satanas, and the (merely) poisonous Boletus satanoides. However I do, as I suspect do all the commercial fungi collectors who pick the stuff which ends up as dried 'porcini' at Waitrose at £5 for 100g.
Boletus erythropus causes stomach upsets when raw but is edible - and good - when cooked. Hence the reason why shop-bought dried mushrooms must always be thoroughly cooked, since you really don't know what's been sneaked in there under the guise of 'cep'.
