How is it that mushrooms can appear so suddenly overnight or immediately after a rainstorm? It turns out that the fungus organism builds the mushroom structure ahead of time. All the cells are there, properly assembled, but very small, in a form called a primordium. When enough water is available, the fungus pumps it into the cells, inflating them like water balloons, and the mushroom pops up.

It's been very damp in Philadelphia of late.

mulch in a planter.
