Well, from excited about theese mushrooms i am now worried about my plants nearby, my research says that armillaria mushrooms/fungus are parasitic to a wide range of fruit and other plants, mainly trees. They infect roots and bases of live trees, slowly killing them by killing of the cambium/bark layer. Tomorrol i will collect them all and discard them, i see alot of white fungus strings and whole clumps under the mulch so i will collect this as well.
Its a total shit that they are edible but can be dangerous to nearby plants, i hope i manage to eradicate them somehow, the fungus below ground is known to be persistent in time....
