Greencracked brittlegill. A variety of wild mushroom which, as its name implies, is a sort of olive green with darker green markings and with creamy brittle gills. 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.
