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.
I got it from the quote in the article from the author of the NEJM paper. You’re correct, but this seems to also happen in maybe 2% of people, and there’s a good chance 145C is only needed to be absolutely certain all sugars have 100% broken down. Hotpots might still get rid of most of it at 100C. I’m not a polysaccharine decomposition expert though, even though I know they’re very heat-sensitive.
If you’re really worried (which you probably don’t need to be given it’s rarity), mushrooms can’t really be overcooked (unless you literally burn them), so nuking them in the microwave with a thin coat of oil or frying them off will help get them to temp if you want to be really certain.

It affects about 2% of people that consume the mushrooms raw or only lightly cooked… in people of all ages, … more often male than female.
…shiitake dermatitis is not seen with the ingestion of thoroughly cooked at a temperature > 145 C.

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