These sizable and striking boletes were growing from the side of a steep hill, in sandy soil, in Zone 51. The steep terrain both helped and hindered photography: helped by making tripod-stabilized shots from the side and even from below possible in some cases, hindered by interfering with footing and navigation of the area.

They have pale pinkish caps and stipes and yellow pores that are somewhat large and angular. Caps become somewhat concave in age and the rims particularly upturn. The stipe is thick, over 1cm, and up to 3 tall; the caps up to 5cm in diameter and again thick, over 1cm.

Some showed what might have been reddish-brownish bruised spots on the pores. I disturbed the pore surface of one and watched for a few seconds; no really rapid reactions observed.

There were at least six of them, in an area of only three or four square meters.
