"Even the homely wood blewits"
are edible mushrooms. They grow in Europe, North America and recently, parts of Australia. Their name comes from an old English word for 'blue'; the mushroom often has a blueish base and stem, which grows darker and reddish with age. Much care should be taken when gathering them for cooking, as they closely resemble some poisonous species; they must also never be eaten raw, as in this state they are indigestible.
