Coprinus comatus, the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shapedcaps open out. The caps are white, and covered with scales—this is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and secrete a black liquid filled with spores (hence the “ink cap” name). This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.
When young it is an excellent edible mushroom provided that it is eaten soon after being collected (it keeps very badly because of the autodigestion of its gills and cap). If long-term storage is desired, microwaving, sauteing or simmering until limp will allow the mushrooms to be stored in a refrigerator for several days or frozen. Also, placing the mushrooms in a glass of ice water will delay the decomposition for a day or two so that one has time to incorporate them into a meal. Processing or icing must be done whether for eating or storage within four to six hours of harvest to prevent undesirable changes to the mushroom. The species is cultivated in China as food. The mushroom can sometimes be confused with the magpie fungus which is poisonous.
The shaggy ink cap is easily recognizable from its almost cylindrical cap which initially covers most of its stem. The cap is mostly white with shaggy scales, which are more pale brown at the apex. The free gills change rapidly from white to pink, then to black. It isdeliquescent. The stipe has a loose ring and measures 10–37 centimetres (3.9–14.6 in) high by 1–2.5 centimetres (0.39–0.98 in) diameter. Microscopically it lacks pleurocystidia. The spore print is black-brown and the spores measure 10–13 by 6.5–8 µm. The flesh is white and the taste mild
It grows in groups in places which are often unexpected, such as green areas in towns. It occurs widely in grasslands and meadows in Europe and North America, from June through to November in the UK. It appears to have been introduced to Australia, New Zealand and Iceland. In Australia the species is sufficiently common to have been featured on a postage stamp issued by Australia Post in 1981
The young mushrooms, before the gills start to turn black, are edible. The taste is mild; cooking produces a large quantity of liquid. It can sometimes be used in mushroom soupwith parasol mushroom. Large quantities of microwaved-then-frozen shaggy manes are delicious when used as the liquid component of risotto, replacing the usual chicken stock.
The agent responsible for unpleasant symptoms when consumed with alcohol, coprine, which is found in Coprinopsis atramentaria, has not been isolated from C. comatus. From Wikipedia, the free encyclopedia
