What the records suggest about Stump Puffball

The project has analysed over a million matched fungal events from Europe and North America alongside weather and habitat data. The patterns may be useful wherever the same fungus occurs, but local climate, trees and soils can change the response.

Weather or season?

The normal seasonal pattern is the more useful guide here. No short-term weather effect passed the project’s checks for a clear, repeatable link.
