White mushrooms might be edible… or they might be poisonous. You can’t tell by color alone. Source: theimagefixer.com
Most garden myths are harmless. They may not be totally true and they may be a waste of time and money, but they won’t kill you. Here’s one that can.
I recently received a letter from a reader (name changed to protect the innocent) asking whether it was true that white mushrooms were always edible. She had some growing in her lawn and was thinking of harvesting them, having heard that white mushrooms were safe to eat.
Mushroom color has nothing to do with whether they are poisonous or not. They can be white, brown, even green or purple, and still be edible. Or they could be poisonous. Never consume a wild mushroom unless you know what you’re doing.
Check out its identity on-line or in a guide to mushrooms or take a sample to a knowledgeable mycologist. Never, ever improvise with mushrooms, no matter what their color!
