This hanging pot of flowers, probably some sort of impatiens, has adored the front of our house for many years*. This morning during a routine inspection, we noticed a small mushroom growing out of the drain hole on the underside of the pot.
The fungus itself, the spore-bearing fruiting body of which is this mushroom, must be within the soil far below the top of the soil. If it weren't for the drain hole, what would the fungus have done?
*The plant survives the winters indoors.
