The International Union for Conservation of Nature (IUCN) has raised an urgent alarm over 1000 fungi species now threatened with extinction worldwide. The latest IUCN Red List update includes 1,300 assessed fungi species, with at least 411 confirmed to be at risk, contributing to the broader tally of over 1000 fungi species now threatened with extinction.

This report, part of the Red List’s 169,420 total species—47,187 of which are threatened—underscores fungi’s vulnerability and the need for immediate action.In Europe, even familiar species like the Vulnerable fibrous waxcap (Hygrocybe intermedia) face decline due to these pressures.

As part of the broader biodiversity crisis, the Red List now tracks 169,420 species total, including 47,187 facing extinction. Fungi, often overshadowed by plants and animals, are vital to life on Earth, and their decline signals a pressing need for action.

Why Are Fungi in Trouble?

Several human-driven factors are pushing fungi to the brink logging, farming, and city sprawl are wiping out fungal homes, endangering 279 species globally. Run-off nitrogen and ammonia from fertilizers and car exhausts poison their environments, impacting 91 species. In places like the USA, changing forest fire cycles threaten over 50 fungi species. Even in Europe, familiar fungi like the Vulnerable fibrous waxcap (Hygrocybe intermedia) are fading fast.

Why Fungi Matter

Fungi aren’t just mushrooms on your plate—they’re ecosystem powerhouses. With an estimated 2.5 million species (only 155,000 named), they help plants absorb nutrients and break down organic matter. They drive fermentation for food, yield medicines, and even clean up polluted sites. As the second-largest kingdom after animals, their collapse would ripple through nature and human systems alike.

IUCN Director General Grethel Aguilar calls fungi “unsung heroes” for their role in holding ecosystems together. With over 411 species confirmed at risk, conservation can’t wait. Protecting these hidden giants is key to keeping nature—and us—thriving.
