Seriously though what even are fungus? Straddling some weird position between plants and animals, containing an impressive amount of shared DNA with humans, engaged in weird psycho-chemical communion with the forest, dancing on the edge of immortality?
Another good example is lichen: it's not a moss, not a plant - it doesn't even have roots; it's a composite organism made out of fungi and bacteria / algae, living together as one organism in a mutual relationship. Hence this quote I like by this guy: Lichens are fungi that have discovered agriculture.
