How would core areating prevent these circles?

As the first step in restoring a lawn to a sustainable garden, core
aerating goes a long way.

To answer your question, TomKan, core aeration allows the soil to get oxygen,
which is generally not a hospitable climate for most fungi or molds. They like
a wet soil or conditions.

As an aside, mushroom circles in the lawn, or "fairy rings" as they are sometimes
called, are not harmful to the lawn. They usually indicate underground wood (old
tree roots, etc.) which is decomposing. The fungi (of which the mushrooms are the
fruiting bodies) are a natural part of the decomposition process. They are typically
seasonal in nature, appearing in spring when the soil temps warm and the climate is
damp with spring rains. You can rake away the mushrooms if you find them unsightly
or simply wait for warm, dry weather when they will disappear.
