Nope. Edible mushrooms generally need similar conditions as mold/mildew/rot to grow, i.e. moisture, low light, and the right material -- though they tend to be pickier, and are less suited to human-adjacent conditions. So if you find mushrooms growing where they shouldn't, there's a much deeper moisture and mold issue.

Lots of houses have unresolved water damage issues.

Termites for instance mostly show up in wood that already has water damage.
