A rare, deadly brain fungus called Cladophialophora bantiana is being detected far more often in the US.

Detections nearly quadrupled between 2023 and 2025, University of Washington lab data show.

The black mould targets the nervous system, with a fatality rate of up to 70 percent.

It lives in soil and decaying matter and likely enters through inhalation or a skin break.

In the brain it forms abscesses that raise pressure inside the skull.

Symptoms include severe headaches, vomiting and vision or memory loss; experts want national tracking.
