On a grey afternoon in late August, a small crowd has gathered near the old hydroelectric power station in Elliðaárdalur, a nature area near the capital. Helena Marta Stefánsdóttir, a specialist in the Forestry Service, has prepared a lecture on mushroom foraging 101 for the amateur mycologists gathered here. But it seems to be the first day of fall and as the wind picks up, a drizzle slowly grows into a light shower. The children are getting restless, and it’s only through their low murmur that I’m able to pick up fragments of tips. Never eat the ones that… Usually, a white mushroom will… I’m not exactly reassured, but everything is getting damp and we head off for the cover of the woods to continue our search.
