When mushrooms decay, they spread spores, which can be dangerous to amphibians. ID'ing a mushroom first to find out if it is poisonous is a must. Was it possible that Cutie was more exposed to the mushrooms than the other frogs, it is possible that the spores of the mushroom could have caused his death... Just a theory.
Also, on a less serious note... toadstools are
not the mushrooms you want becaue the term “toadstool” (from the German "Todesstuhl" — death's stool) is the name commonly given to poisonous mushrooms! lol!
