King bolete (porcini)

Boletus edulis

When
Typically August – NovemberAugust, September, October, November. Earlier in the south, later in the north.
Where it grows
Under conifers and oaks; spectacular flushes along the Pacific coast after the first autumn rains.
How to know it
Fat white stem with a fine raised net near the top, brown 'bun' cap, and a sponge of white-to-yellow pores that never stain blue.
Look-alikes
Bitter bolete (Tylopilus) has pink pores and ruins a dish; boletes with red pores or that stain dark blue should be left alone.
Harvest and use
Slice and dry — the flavour concentrates. Firm young buttons are the prize.
