Birdseye view of mushroom in the soil and opening |
A. The mushrooms are a type of fleshy puffball
mushroom (inedible and perhaps poisonous) that grow underground off of rotting
wood or even rotting woody roots and then open above ground to release their
spores. They can spread but only if they have something to feed on underground
such as rotting wood or roots.
I have received other pictures of the same type from other readers.
