Late summer and early autumn is the season when many (perhaps even most) Swedes bunk off from work early to roam their local forests, bringing back giant hauls of tasty chanterelles (kantareller), trumpet chanterelles (trattkantareller) and ceps (karljohansvamp). You might want to decouple from technology during your mushroom hunting, but a phone is very useful for tracking your location, and noting down where you find good spots, and also for photographing what you find and getting help identifying it on Svampguiden or Svamp-Klapp. Many Swedes leave the root of the mushrooms, believing that this will help them grow back, but as mushrooms are just the fruiting bodies of vast underground networks, in reality leaving the root doesn't make any difference at all.
