Based on color and form, this looks like Boletopsis grisea, but the habitat fits B. leucomelaena. This is like the reverse of the situation reported by Watling & Milne – they found a new species (based on molecular characters) in Scotland that looked like B. leucomelaena but had the habitat (pine) of B. grisea.

[admin – Sun Nov 14 14:13:21 +0000 2010]: Changed location name from ‘4.5 km NE of Pitkin, Gunnison Co., Colorado, USA’ to ‘4.5 km northeast of Pitkin, Gunnison Co., Colorado, USA
