I checked several references that I have, and couldn't find it at all
Max. Mushrooms by Hard, Chang and Hayes' The Biologcy and Cultivation
of Edible Mushrooms, and Benjamin's Mushrooms: Poisons and Panaceas
had no reference to hydrolamine at all.

Is there a particular reason you would expect fungi to have this
chemical? Would it be specific to one group of fungi?
