The phrase "Little Brown Mushroom" doesn't mean much other than the obvious. It doesn't tell you much about the mushroom, nothing about it's habitat preferences or it's ecological role, it doesn't give you any taxonomic information, or whether it's edible or poisonous. It sort of means I've seen a mushroom that's small, drab, and I don't want to take the time to learn much more about it. However, there seems to be an abundance of LBMs in the world. Why so many mushrooms that are little and brown? Someone looking at the question from an evolutionary perspective might wonder what advantages there are to being a small, brown, and overlooked mushroom. Maybe it's just that you can more easily avoid being eaten by (small, brown and hungry) fungivores. From a more spiritual perspective, one might wonder why the creator (etc) has a fondness for the small and brown. Whatever the reason, LBMs are everywhere, and yes they are important, quietly and inconspicuously doing the work of decomposing, parasitizing, or mycorrhizalling the world.
I think they are great, partly for the reason that they are everywhere and not many people look at them, partly because it's a fun challenge to try to ID them (I know how to have a good time), and partly because some them are really interesting, even if you don't care about mushrooms. LBMs have a lot going against them as far as popularity contests go:
- Little is not generally admired; maybe if they were SSBM, Super-sized Brown Mushrooms, they'd get more attention.
- Brown is not one of most people's favorite colors.
- Mushrooms (at least in this country) are feared and reviled.
- It's edible (rated good to delectably delicious by various sources).
- It grows in fairy rings, which evokes mystery and fantasy.
- It can dry out and then completely revive after re-wetting, even producing spores again.
- It's poisonous.
- Deadly poisonous.
- One of the most poisonous mushrooms you can find.
- It's hallucinogenic.
- It's used by some to commune with the divine.
- It's used by some others for "recreation" (or to simulate, imitate, or pretend to commune with the divine).
- It's small.
- It's brown.
- It's a mushroom.
As you may have noticed, there's no picture of it; it's because you have probably never noticed or heard of this mushroom.
By the way, the mushrooms in these pictures have been painted with a complete disregard towards accuracy and detail. They are the based on the product of an afternoon drawing with my five year old daughter Naomi and were done entirely for the sake of fun and imagination.
