Bitter Bolete: common questions

When is Bitter Bolete in season?

Bitter Bolete is generally in season from January to December in temperate northern regions. The exact timing shifts with latitude, elevation and each year's weather. Check the Season Finder for your own location.

Is Bitter Bolete safe to forage?

Toxic look-alikes: Rooting bolete, Penny bun, Bay bolete. Only forage with a confident ID. Never eat any wild plant, berry, nut or mushroom unless you are completely certain of the identification. Check every find against a reliable field guide, and when in doubt, don't.

One note before you head out

Forage helps you discover and identify wild plants, but identification is never 100% certain. Many edible plants have toxic lookalikes. Never eat anything you find based only on what this app tells you. Always confirm with a field guide, an experienced forager or a local expert. The season score tells you where to look, too: it’s not a guarantee. Mind conservation law and property rights as well.
