SvampdagsIs it mushroom time where you live?

The mushroom outlook for every town in Sweden, day by day, built on the rain, the warmth and the forest around you. It shows when the conditions begin to favour chanterelles, penny buns and the rest, so you know when it's worth taking the basket.

Watch your area light up

Follow the moisture as it moves across Sweden after rain, for all species or for the one you're after.

Today's mushroom letter · 30 September

“It's beginning to stir in the forest in several places. It looks best in Norrbotten, Västra Götaland, Jönköping and Halland. Funnel chanterelle leads in the most counties.”

The one rule

Turn the mushroom over

The underside says more about what you're holding than the colour, the shape or the place.

“If the mushroom has gills, leave it. Unless it bleeds milk.”

Sweden's serious mushroom poisonings have one thing in common: every one goes through a gilled mushroom mistaken for another gilled mushroom. So Svampdags follows no gilled mushrooms at all, with a single exception. That costs a few popular species, and Svampdags takes that cost.

NeverGills

Thin blades, close together, that you can count. Like paper against your finger. Every deadly mix-up in Sweden has this underside.

The one exceptionGills that bleed milk

Break it, and white or orange milk runs from the break. The milkcaps do that. No deadly poisonous mushroom in Sweden does.

BoletesPores

A spongy layer full of small holes, all in one piece. You can't pick out a single blade.

Tooth fungiSpines

Small separate spikes that hang straight down, and rub off under your thumb.

ChanterellesFalse gills

Blunt ridges, far apart, that fork and, most important of all, carry on down the stem.

This is Svampdags' rule for which species it follows. It is not a guide to identifying mushrooms. Read the full safety guide ↗ before you pick, and never eat a mushroom you aren't sure of.

“Mushrooms are about when.”

Moisture, temperature, season and the forest where you live, weighed together to show when the conditions begin to favour the mushrooms. They're fickle, so take it as a hint.
