Primrose brittlegill

The cap grows to around 10 cm (4 in) in diameter. It is commonly purplish-red, but brownish, and greenish forms have been recorded. Usually it is darker in colour towards the middle, which is convex when young, but becomes depressed in the centre with age. The stem is occasionally white, but more commonly is flushed with pale purple-red, and has a grape-like; easily removed bloom. It is 3–8 cm tall and 1–1.5 cm in diameter. The adnexed to slightly decurrent gills are pale primrose yellow, and they darken with age. They are narrow, and exude water droplets when young.(see photograph left) They also turn slowly pink when ammonia is dropped onto them. This identifies the mushroom to species level, and is a ‘must do’ test for the rarer colour forms. The spore print is cream. The flesh is firm, and has a very hot taste, making the mushroom inedible.
