Fruits after warm, humid spells when soil temperatures sit in the mid teens Celsius and a good soaking rain follows a warm period. A typical trigger is heavy rain after several warm days, with flushes appearing roughly one to two weeks later.
Brown bun shaped cap, often greasy when damp. The underside has a sponge of pores, white at first then turning yellowish to olive, never red. The thick bulbous stem is pale with a fine raised white network near the top, and the flesh is white and does not change colour when cut. Smell is pleasant and nutty.
Often shares ground with chanterelles, other boletes like the bay bolete, and amanitas including the toxic fly agaric and death cap, so identify everything carefully. The reddish fly agaric under birch and pine is a useful indicator that conditions may suit cep nearby.
Check around the bases of host trees and along sunlit forest edges, returning to productive spots a few days apart through the flush. Cut or twist the stem cleanly, slice each cap to check for maggots, and take only young specimens with white firm flesh.
Keep fresh caps in a paper bag in the fridge and use within a couple of days, as they spoil and get wormy fast. Slicing and drying is the classic long term method; they also freeze well if briefly sauteed first.
Can be confused with the bitter bolete (Tylopilus felleus), which has a darker net on the stem, pinkish pores when mature and a strongly bitter taste, and with red pored boletes. Avoid any bolete with red or orange pores or flesh that stains strongly blue.
