Powdery Sulphur Bolete
A bolete whose young cap and stem are coated in a bright sulphur-yellow powdery veil. The veil leaves remnants on the cap edge and a flimsy ring as the cap center turns orange-red to reddish brown. The pores bruise greenish blue. It grows mainly with conifers and is widespread in North America, with records from Asia and Australia.
Reported as edible (Wikipedia; Horn's Boletes), but little documented as food, and the taste can be acidic or acrid. The bright yellow powdery veil makes it distinctive.
