<a href="https://en.wikipedia.org/wiki/False_morel" class="extiw" title="en:False morel">False morel</a> fungi (<i><a href="//commons.wikimedia.org/wiki/Gyromitra_esculenta" title="Gyromitra esculenta">Gyromitra esculenta</a></i>) for sale at a department store in <a href="https://en.wikipedia.org/wiki/Helsinki" class="extiw" title="en:Helsinki">Helsinki</a>.  Though deadly poisonous unless properly parboiled, these mushrooms are considered a local delicacy, and Finnish law permits their sale fresh as long they are accompanied by conspicuous warnings and government-approved preparation instructions.  (The mandatory warning label was originally hanging above the mushrooms; I moved it, with the permission of the staff, down to get both into the same picture.)
