Not All Bad: Gyromitrin mycotoxin has a limited distribution in edible false morels (Gyromitra)

- False morels (Gyromitra spp.) are iconic fungi primarily for what they are not - morels (Morchella spp.), the highly sought after, wild foraged mushrooms. Every morel hunter is taught to recognize and avoid false morels because they may carry a mycotoxin called gyromitrin (acetaldehyde N-methyl-N-formylhydrazone). While there are only a few deaths associated with gyromitrin in recent times, poisonings can result in liver and kidney damage, and repeated exposure may cause neurodegenerative diseases. Despite these risks, some intrepid mushroom hunters enjoy eating false morels. Despite false morels’ infamy as both delicacy and deadly poison, we previously had a limited and largely anecdotal understanding of which species contained the toxin. We developed a new, highly sensitive gyromitrin assay using ultra high-performance liquid chromatography and surveyed the false morel family Discinaceae for gyromitrin production. Gyromitrin has a more limited and discontinuous distribution than expected, consistent with a model of rapid evolution coupled with horizontal transfer.

Terrific presentation, so cool that someone is working on this stuff!
This is fascinating, I’m totally dorking out on this.
i got brunnea and one that looks more like the korfii. logan county ohio. also ate the brunnea just some salt water to get rid of any bugs. rinsed. and fried up with eggs veggies and seasonings. did not try eating the korfii looking one since i am unsure on I.D.
Do you have a picture of the brunnea?
@@DallasFeys several pictures. some found in the wild some found in the skillet lol
Well I got good news for you: The gyromitrin-bearing species, G. esculenta group, doesn’t occur in Ohio. G. esculenta group likes cooler climates, either in the mountains or in the far north (like central-northern Michigan, New England, etc.)
Great video. Family has always been big on true morels as well as beefsteak reds
You mean Fistulina Hepatica, right?
12 minutes in and still waiting for someone to address the topic. Already there has been misinformation by the guest speaker. Well I'm already this far in I guess I'll keep watching.
we have chapters on all of our videos so you can skip the introductions and go right to the lectures! hopefully you kept watching :)
what misinformation was there in the first 12 minutes?
