What the records suggest about Devil's Urn

The project has analysed over a million matched fungal events alongside weather and habitat data. These findings describe patterns in the study, not conditions that every fruitbody must follow.

Tree associations

Of the tree types tested, Devil's Urn was most often recorded where willow was present.

Weather or season?

Recent weather added a smaller but repeatable signal after the normal seasonal pattern had been allowed for.

When does this mushroom tend to appear?

The middle line means there was no difference between this species and other fungi recorded in the same area and part of the season. Warmer and cooler always mean warmer or cooler than normal for that place and time of year, not absolute temperature.

Each point is a separate matched comparison for that weather measure and time window. Clear results must have a meaningful effect, adequate geographic coverage and the same direction in odd and even years. These are associations in field records, not rules or forecasts.
