Tricholoma pardinum
Tricholoma pardinum is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. Ingesting T.pard in small quantities results in a severe, persistent gastroenteritis caused by an unknown mycotoxin. The species has been implicated in a number of episodes of mushroom poisoning.
About Tricholoma pardinum in brief
Tricholoma pardinum is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. First officially described by Christiaan Hendrik Persoon in 1801, T. pardinum has had a confusing taxonomic history that extends over two centuries. Ingesting T. pard in small quantities results in a severe, persistent gastroenteritis caused by an unknown mycotoxin. The species has been implicated in a number of episodes of mushroom poisoning, probably because it is a large, attractive mushroom with a pleasant smell and taste. It is found in beech woodland in summer and autumn. Two subspecies have been described from southern Europe. It lies within the subgenus Pardinicutis of Tricholomas, a grouping of similar species characterised by grey, brownish caps that are woolly or covered in small scales with micrometres in the clamp connections in the spores. molecular analyses suggest that T pard inum is closely related to T huronense, Tmutileenatum, T mutile, and T venenatum. Another variety has been described as T guentatum varinum varosum, an uncommon variety, which produces mushrooms with more fibrillose caps and stalks than the typical variety.
The fruit body is an imposing mushroom. It has a pale grey cap up to 15 cm in diameter that is covered with dark brownish to greyish scales. The gills are whitish, and are not attached to the stout white to pale grey-brown stalk. The spore print is white, and the spores are hyaline, or white with a whitish tinge. It can be found in southern Europe, where it associates with chestnut and spruce trees, and where it is more common than in North America. It also grows in the UK and the U.S., where it has been found in oak and birch trees. The mushroom has been used in some European field guides, but has been applied in error to this species. There has been confusion over which scientific name to use for over two hundred years. French mycologist Lucien Quélet reclassified it as a species in 1873, giving it its current binomial name.
