>>2719007>>2719034do / did you use woodchips from a factory of some kind at some point?
could the mushrooms have absorbed any chemicals? (i could see if you did previously, without any problems, the chemicals could have broken down &/or leeched into the pile over time too)
besides that, like
>>2719011 said, mushroom are a thing where people can eat them for years, then one day become allergic, wild mushrooms especially
if you're willing, i'd say maybe carefully give it one more try a while later, then see if it comes back, if so, immediately stop
you might wanna get a blood test in case it damaged any organs, if there was damage, you probably still have some dead cells floating around in your blood right now
