Butyriboletus frostii
A species of Butter boletes. Also known as Apple bolete.
With its striking apple-red hue and distinctive bark-like stem, Frost's bolete is a popular subject for photographers.

Furthermore, this mushroom typically exhibits a blue discoloration when handled and may exude tiny yellow liquid droplets on its pore surface.
