The powdery brittlegill is a variety of wild mushroom, ranging in colour from blue to light green or grey. Most brittlegills resemble other ones that are inedible and some will cause gastric problems. You can normally detect what type it is by the flavour. A tiny tasting will immediately reveal whether or not it is edible, but it is worth spitting it out immediately if you detect a bitter taste. (If gathering mushrooms you must be absolutely certain what you have before you eat them as many are very poisonous.)
