I have mushrooms on my property.
I noticed after one controlled burn, some kind of fungus sprung up within a week. The size of a US football, very fast growing.
What scares me about mushrooms is, I feel like I need to know ALL the species, so I can separate the poisonous ones from the non-poisonous ones.
I grasped the basic part about trying new foods, you just take a small bite. 1/10 gram or something.
