I have been growing other plants as well as cannabis and the one plant I have the most pride in us my avocado plant. a few days ago I noticed mushrooms popping up on the soil, I'd pick them off and throw them away then wash my hands, if I skip a watering of the plant or the soil gets too dry the mushrooms die, but new ones keep popping back up. any idea what it is? Is it toxic? Is it beneficial?
