I’m only just getting around to identifying the half dozen species of boletes I encountered while camping in Larch forests around Seeley Lake last summer. These fungi are all edible (although not always palatable and often infested with fly larvae) and comparatively easy to ID correctly. This genus is most readily recognized by its angular pores that radiate out from the stipe like cells on a leaf. Nearly all members of this genus are ectomycorrhizal symbionts with conifers here in the PNW. This species in particular is almost always found under Larch trees (Larix) in the late summer and early fall. Its cap is dry and scaly and tends to be rosy in the middle and orange-yellow (ochre) towards the edge. Apparently this species is best when dried, but is not often eaten because of its acrid or bitter taste.
