mushroom is common in Southern California lawns. Most of the mushroom
fungus is hidden under ground in the from of many wide spread,
microscopically thin threads. The mushroom we see is the fruiting body
which produces spores, and distributes them to the wind.
Here is the mushroom from a different angle.
The gills start out
pink then gradually turn brown, and finally almost black. Note
that the gills are free (not connected to the stem), and the ring where
the edge of the cap was attached to the stem.
the mycelium (the tangled thread like
body of the fungus) may continue growing in the soil for many years, we
are not likely to see it. When mature, a dense mass of the threads
forms below the surface. When conditions are right, wet and humid, the
expands upward rapidly as a button.
Sometimes mushrooms come up in tight corners and get squashed out of shape.
