Poor bastard must have been itchy as fuck. Sadly the article on a shitty ad infested site is also padded out for word count. So here is the important parts. Hand-summarised, unlike the AI-assisted article:

A 72-year-old man presented with a 2-day history of an itchy, linear rash across his back. Two days before symptom onset, he had prepared and eaten a meal containing shiitake mushrooms. - Paywalled report from New England Journal of Medicine
Caused by the carbohydrate lentinan which triggers the release of interleukin-1 (and other chemicals), which causes cause inflammation.
The rash develops usually 2-3 days after eating undercooked shiitake.
Lentinan is broken down when thoroughly cooked at temperatures over 145° C / 293° F

Because fuck shitty pop-science padded journalism and their marketing strategies and hostile UX, and fuck the NEJM too for paywalling medical research.

Not sure if the 145°C is a citation/translation error by the site. If the mushroom is boiled in water (e.g. hotpot), it will never reach those temperatures.

Searched for it, multiple sites give 130-145°C.
