Scattered to gregarious under red fir (Abies magnifica) in the Sierra Nevada Mountains; fruiting in the fall, rarely in the spring.
This bolete can be distinquished by blue-staining, bright yellow pores that turn red as it matures (except at the pileus margin, which remain yellow) and its association with red fir.
