Mushrooms are the fruiting bodies of fungi, appearing above ground only when conditions suit them.

The longer version

Most of a fungus lives out of sight as a network of fine threads running through soil, wood, or leaf litter. What people call a mushroom is only a temporary reproductive structure, produced when temperature, moisture, and food reserves line up.

The visible cap carries spores on its gills or inside its pores, and these are shed into the air to land elsewhere. Between fruitings the network keeps growing and feeding unseen, so an absence of mushrooms says little about whether the organism below is present and active. A ring of mushrooms appearing on a lawn often marks one organism spreading outward below the surface.
