Bolete

The boletes, or fleshy pore fungi, are a conspicuous element of the summer and fall "mushroom" flora of Michigan.

When gathering boletes and other mushrooms for food, avoid picking from polluted habitats such as along heavily trafficked roads, along railroad tracks or power line clearings, near landfills or roadside litter dumps, and chemically treated lawns.

Any bolete that matches the traits described above should instantly react with a turquoise color change when a drop of ammonia is placed on the stem. If it doesn't, you've got the wrong mushroom.
