Neoboletus luridiformis

Neoboletus luridiformis, also previously known as Boletus luridiformis and (invalidly) as Boletus erythropus, is a fungus of the bolete family, most of which produce mushrooms with tubes and pores beneath their caps. It is commonly known as the scarletina bolete, for its red pores, which are yellow when young. Other common names include the red foot bolete, dotted stemmed bolete, or dotted stem bolete.

It is found in Northern Europe and North America. While edible when cooked properly, it can cause vomiting and diarrhea if not.
