why are so many different clumps of mushrooms appearing in this particular year? and what do ground slugs do to them? do they eat them or is a symbiotic relationship whereby the slug cleans the mushroom, thereby giving it some medicine or food that it needs? slugs are not on all mushroom clumps, only some. why is that?
