False morel mushrooms. They are deadly poisonous if not cooked, closely resembling real morel mushrooms, being wrinkled and brown in the same way. However, morel mushrooms are symmetrical while false morels are irregular in shape and look like a brown brain, while true morels are more like a sponge. True morels have hollow stems while those of false morels are solid. Be careful to check each of these features before attempting to eat one. They have a fine flavour and are generally parboiled. They are popular in Nordic countries and in Finland especially.
