Other N-methyl-N-formylhydrazone derivatives have been isolated in subsequent research, although they are present in smaller amounts. [34] Evidence suggests that children are more severely affected; it is unclear whether this is due to a larger weight consumed per body mass ratio or to differences in enzyme and metabolic activity. [47] Cases of severe poisoning may progress to a terminal neurological phase, with delirium, muscle fasciculations and seizures, and mydriasis progressing to coma, circulatory collapse, and respiratory arrest.

[34] Additionally during the metabolism of MMH, N-methyl-N-formylhydrazine is produced; this then undergoes cytochrome P450 regulated oxidative metabolism which via reactive nitrosamide intermediates leads to formation of methyl radicals which lead to liver necrosis. The spore print is whitish, with transparent spores that are elliptical and 17–22 μm in length. Gyromitra esculenta can be distinguished from other false morels by its brain-like texture, reddish-brown color, and relatively thin stem. There is no way to know.
