Ancient Fossil Unveils Oldest Disease-Causing Fungus

The oldest disease-causing fungus, Potteromyces asteroxylicola, has been discovered in a 407 million-year-old fossilized plant specimen at the Natural History Museum in London. The parasitic fungus had burst through the plant's outer wall, killing its host's cells and absorbing its nutrients. This is the earliest recorded evidence of a fungal parasite causing disease in a plant, shedding light on the early evolution of fungal species. The fungus is named after children's writer and mycologist Beatrix Potter.

"Unprecedented: Tree fungus infects humans for the first time"

A 61-year-old mycologist in India contracted a fungal disease caused by Chondrostereum purpureum, a fungus that typically affects trees and had never been reported in humans before. The patient had difficulty swallowing, hoarseness, cough, lack of appetite, fatigue, and recurrent inflammation of the throat for about three months before seeking medical care. The infection was successfully treated with a procedure to drain the pus from his neck followed by a two-month regimen of broad-spectrum antifungal pills. Since this is the first time a C. purpureum infection has been observed in a human, it's unclear how likely it is to occur in others or how such infections can best be treated.

Global First: Human Infected by Dangerous Plant Fungus

A man in India was diagnosed with a potentially deadly fungal infection caused by the plant pathogen Chondrostereum purpureum, which was discovered by DNA sequencing after various tests failed to identify the fungus. The man denied having worked with such a plant pathogen, but his recurrent exposure to decaying material may have caused the rare infection. The study's authors warn that global warming and other civilization activities could lead to the emergence of newer fungal diseases in the future.

World's First Case of Human Infection by Rose-Killing Fungus Reported

A man in India became the first recorded person to get sick from a fungus that usually attacks rose plants. The fungus, Chondrostereum purpureum, causes a disease called silver leaf in plants. The man, who had a healthy immune system, was a plant mycologist and worked with decaying plant material and other fungi in his research. The doctors speculate that recurrent exposure to the decaying material may have caused the rare infection. While this case is likely a fluke, the report authors note that the past few decades have seen a reported rise in human fungal pathogens.
