Summary
Source: WikipediaRussula emetica, commonly known as the sickener, emetic russula, vomiting russula, is a basidiomycete mushroom, and the type species of the genus Russula. It was first described in 1774. It has a red, convex to flat cap up to 8.5 cm (3.3 in) in diameter, with a cuticle that can be peeled off almost to the centre. The gills are white to pale cream, and closely spaced. A smooth white stem measures up to 10.5 cm (4.1 in) long and 2.4 cm (0.9 in) thick. There are many similar russulas with a red cap and white stem and gills, some of which can be reliably distinguished only by microscopy. The mushroom has a wide distribution in the Northern Hemisphere, where it grows on the ground in damp woodlands in a mycorrhizal association with conifers, especially pine. The mushroom's common names refer to the gastrointestinal distress which it causes when consumed raw. The flesh is extremely peppery, but this offensive taste, along with its toxicity, can be removed by parboiling or pickling. Although it used to be widely eaten in Russia and eastern European countries, it is generally not recommended for consumption.

Edible Uses
The bitter taste disappears on cooking and it is said to then be edible, though consumption is not recommended. The mushroom used to be widely eaten in eastern European countries and Russia after parboiling (which removes the toxins), and then salting or pickling. In some regions of Hungary and Slovakia, the cap cuticle is removed and used as a spice for goulash.
Known Hazards
As its name implies, the sickener is inedible, though not as dangerous as sometimes described in older mushroom guides. The symptoms are mainly gastrointestinal in nature: nausea, diarrhoea, vomiting, and colicky abdominal cramps. These symptoms typically begin half an hour to three hours after ingestion of the mushroom, and usually subside spontaneously, or shortly after the ingested material has been expelled from the intestinal tract. The active agents have not been identified but are thought to be sesquiterpenes, which have been isolated from the related genus Lactarius and from Russula sardonia. Sesquiterpenoids that have been identified from R. emetica include the previously known compounds lactarorufin A, furandiol, methoxyfuranalcohol, and an unnamed compound unique to this species.
Distribution
It is a tropical and subtropical plant.
