About Suillellus luridus in brief

Summary Suillellus luridusSuillellus luridus is a fungus of the family Boletaceae. Fruit bodies appear in summer and autumn and may be locally abundant. It is a firm bolete with an olive-brown cap up to 20 cm in diameter. It can cause gastric upset when eaten raw and can be confused with the poisonous Boletus satanas. When consumed with alcohol, it has been implicated in causing adverse reactions similar to those caused by the compound coprine, though laboratory testing has not revealed any evidence of coprine in the mushroom. Several varieties, a subspecies, and a form have been described by European mycologists. The species is mycorrhizal, forming a symbiotic association with broad-leaved trees trees as oak, chestnut, birch and beech. It has been found to have a growth-enhancing effect on conifers in experiments. The fruit bodies are highly attractive to, and often infested by, insects, and several species of fly have been recorded feeding on them. The specific epithet is the Latin adjective Luridus,’sallow’ and is a nomen nudum. It was first described in 1774, but has been transferred to various genera in its taxonomic history, although it retained the original name given to it by German botanist Jacob Christian Schaeffer until a transfer to genus Suillells in 2014. The mushroom is found in calcareous broadleaved woodlands in Europe.

It stains blue when bruised or cut, and is edible and good when cooked. The fungus is a member of the Boletidae family. It is found in Europe and North America, Asia, Australia, Africa, and the Middle East. It also grows in Asia, Africa and the Pacific, where it can be found in Asia and the Americas. It causes gastric upsets when eaten and is often mistaken for the poisonous boletus sitanas, which is also found in some parts of Europe and the Faroe Islands. The mushrooms are edible when cooked, but can be dangerous if eaten raw. They are also attractive to insects and have been reported to be infested with a number of species, including some that are known to feed on the fruit bodies. A subspecies of the mushroom has been described, but it has never been validly published and is never considered validly a nudum and is not a valid species. The type species is BoletUS luridUS fainanensis, found in Hainan Province, China, and later elevated to status of species by Jiri Jiri Hlavák in 1995. The variety B. erython var.  threntheron was later described as a distinct species by Albert Bezděkk and Jiri Jiri Pilát, and finally as the subspecies B. Pilát  var  pilácini was defined in 1997. B. caucasicus, later recombined as an independent species, was elevated to species status.
