How to separate similar species

Penny bun often has a greasier cap and netting concentrated near the top of the stem. Bitter bolete develops pink pores and a darker net; no single feature is sufficient, so compare the entire fruitbody.

Interesting facts

Did you know? It often fruits earlier in the season than penny bun; the pronounced stem reticulation is an important feature.
