This all blood-red bolete has moist, convex to flat cap 2 to 6 inches across, with yellowish flesh. The tubes are sunken around the stalk.

Notice how much of the red color has been washed away by heavy rain, as opposed to the sculpture (top), modeled after a fresher specimen, and photo of the fresher mushroom below

The stalk is 1-5/8 to 4-3/4 inches long, 3/8 to 1 inch thick, covered with a web pattern called reticulation.

The spores are olive-brown.

Then entire mushroom turns blue instantly when you bruise or cut it.

Some people have gotten away with eating this bolete, which reportedly isn't particular tasty, while others experience gastrointestinal poisoning (vomiting and diarrhea). Consider it poisonous. It's certainly one I'd never be tempted to try!
