Mushrooms are often seen growing across the US, from urban areas and suburban yards, to forests and public parks. You’ve probably also seen some sprouting along sidewalks or under trees.
But does it seem like you’re seeing more mushrooms than ever before? That’s because you probably are!
This recent surge of fungi is a sign of deeper environmental changes — and the numbers tell a story that’s hard to ignore.
Over the past 50 years, average temperatures have risen by about 2°F, and rainfall patterns have shifted dramatically in many areas, especially across the U.S.
With all this extra warmth and moisture, mushrooms have found their sweet spot.
Fungi need damp conditions to spread their spores, and with 1.5 times as many “wet days” on average compared to past decades, conditions are too perfect for them not to thrive.
Intense downpours are also on the rise, creating microclimates where mushrooms can grow at rapid speed.
And the shift is more than meets the eye.
Even the types of mushrooms showing up are changing.
“Species that were once rare in certain areas are becoming commonplace. For instance, Amanita muscaria, the classic red-capped mushroom, is appearing in suburban yards where it wasn’t seen before”, says Glenn, media correspondent for Backyard Pests.
“These species adapt quickly, taking advantage of new, favorable environments created by climate shifts”, he concludes.
But be warned – eating even a small amount of the wrong mushroom can lead to severe liver damage or death. Identification mistakes are dangerous and more common than you think, even by people who know mushrooms well.
The rise in mushroom numbers is a growing risk, especially for curious kids and pets. If you, a pet, or someone you know eats an unknown mushroom, get medical advice immediately from a professional.
