Boletellus russellii

This mushroom was in bad shape when I found it, but I took some shots of it anyway because it was so interesting looking!

The cap was reddish brown (faded), dry, velvety, and had an inrolled margin. The pores were yellowish green and bruised when marked. The stem was reddish brown, 20 cm long, and deeply furrowed longitudinally. It was growing alone, on the ground, in a deciduous forest.
