>>1885741>>1885760Depending on where anon is, it could also be a different type of Amanita. In the southeast US we also apparently have Amanita flavoconia, which looks basically identical, but the patches left by the veil are yellow instead of white. And my field guide says those are poisonous whereas it at least mentions that A. muscaria has been collected and eaten for its psychotropic properties, even if they don't recommend it.
>>1886193To reiterate what the other anon said, this type of mushroom requires a tree to grow in symbiosis with. Without the particular species (or group of species) of trees, this mushroom will not grow at all. Most mushrooms are broken down into two groups: saprotroph/saprophyte (breaks down dead organic matter) and mycorrhizal (lives in symbiosis with plants, usually trees). With the mycorrhizal mushrooms, they actually grow into the roots of trees and exchange nutrients with the tree, helping both the mushroom and the tree thrive. And, again, without the tree, the mushroom will not grow.
Another important point, as you seem fairly new to the world of mushrooms, is that the above-ground mushroom that you pick is more like the "flower" or "fruit" of the fungus organism (mushrooms are often called the "fruiting body" of a fungus for this reason). Just like how you can't pick a flower off an apple tree and stick it in the dirt and keep growing an apple flower, you can't pick a mushroom and just plant it to grow more. The rest of the fungus that allows it to keep growing (think like the roots, trunk, branches, and leaves of a tree) and producing more mushrooms is a network of fine white "hairs" underground, called hyphae or mycelium. If you've ever kicked over some rotting wood and seen a branching network of white stuff on the underside, that was the "body" of a mushroom. And if you want to grow more mushroom producing "plants", you plant their "seeds", i.e. the spores that drop from the underside of the mushroom cap.
