A company grows these (and other mushrooms) in a warehouse here in Zurich to supply restaurants and grocery stores, which is probably one of the reasons these mushrooms are now found in the wild.

I "hunt" (in German you use the verb "collect/gather") mushrooms in the forests around Zurich and I haven't seen these yet. They also don't appear in my Pilzfürher app specific to Switzerland. But I have heard they are here. From pictures I've seen of them in the wild I might dismiss them from a distance because I could mix them up with two common yellow mushrooms here - one poisonous.

(I'm going out to search for morels this weekend)
