Thanks to the comrade /u/nohaybanda , who told me I should go out anyway even if i did not find anything. Was fun and relaxing. Met some nice old ladies who were much better at foraging than I am.
I am going to put the parasol in a panade and fry them in fat.
Who would want to eradicate them anyways? Yet I remember them not sprouting in fields recently plowed (like in the last years or so).
Also, if you are close to a farm where they do forage silos, (especially the ones with no fixed place for it and not-baged), search for mushrooms where a silo was in recent years, they grow INSANELY BIG there.
I was thinking about over-use. A few species where I live are endangered because they were almost collected to extinction. Some mushrooms are so rare nowadays that you only find them once every decade.
Thanks for the tip with the silos.
Hmm, I would think it's not because of over-harvest (since most mushrooms have enormous myceliums that expand asexually), but because mushrooms have very specific fruiting conditions. Like, the parasol fungus are rocking all year living in the earth, but only sprout when humid/rainy and cold-without-freeze for a few days. So I blame climate change :agony-deep:
