Agaricus hondensis is one of several similar woodland
Agaricus species that can cause flu-like symptoms when eaten. Similar
poisonous species include Agaricus helodes and Agaricus silvaticus.
The odor of these woodland species is mild or of phenols or creosote
and all stain yellow when a drop of KOH solution is applied to a piece
of the flesh (diluted Dranoâ would work).
While some people can eat these without ill effect, they are suspected
of containing phenol, which is probably the cause of the resultant flu-like
symptoms. Similar choice edible Agaricus species all have a pleasant
almond odor and stain yellow slowly with KOH.
