Out of the other Gyromitra species only G.
#Morchella galilaea free
ambigua isn’t out yet, but seems some or all specimens may be gyromitrin free at least in NA) have worrisome levels of gyromitrin (hydrolyzes to MMH which people call “rocket fuel”). ambigua and showed no gyromitrin, however they have implicated in poisonings in Europe. ambigua used to be included, but after talking to Alden some of his aff. Of these only Gyromitra esculenta group (G. If “false morel” is going to be used it’s best applied to the genus Gyromitra given it’s the only morel-like asco genus that contains dangerously toxic species. Sometimes others will occasionally not be hollow as well. Morchella exuberans for example is never completely hollow. It’s also worth mentioning that whilst not being any safer the hollow rule also excludes some Morchella. folds/convoluted caps to separate most morels from anything else with the exception of Verpa which will have folds, but look much more like a typical morel than any Gyromitra and will also have “cottony” filled stipes. They happen to also be hollow (their caps are fairly different looking and attach differently so they are fairly easy to tell apart when you familiarize yourself with them) which sadly means the “hollow” rule doesn’t actually do anything to protect anyone. The only dangerously toxic potential look alikes for morels are in Gyromitra esculenta group. More recently published guides are also starting to label them edible again. So really Verpa should be considered morels and are best labeled “early or thimble morels” like they had been before the 70s and also still are in non-English countries. The rare neurological symptoms attributed to them have also been shown to be caused by Morchella.Īnd as you can see here Morchella cause issues far more often than Verpa (probably partially because they are eaten less) but importantly with the exact same symptoms. As it turns out Verpa happen to be in the Morchellaceae with Morchella and are equally edible/absent gyromitrin. The rest of the world on the other hand continued to call Verpa morels and eat them/sell them commercially. Everyone ran with the fear and recommended against them, but only in English speaking countries where the book was published (America originally). The sad thing is the only reason people wanted to separate them and started calling Verpa “false morels” is because a book in the 70s mentioned they MIGHT contain gyromitrin with no real evidence they did. So the “hollow” rule originated to separate Verpa from Morchella. So with the season taking off here’s almost everything you need to know about morels and any of their potential look alikes.
