Pleurotus ostreatus
"Omphalotus nidiformis" may be confused with the edible brown oyster mushroom ("Pleurotus australis"), which is brown and does not glow in the dark. Confusion with another edible lookalike, "Pleurotus ostreatus", common in the Northern Hemisphere and cultivated commercially, has been the source for at least one case of poisoning reported in the literature.
