Tylopilus

''Tylopilus'' is a genus of over 100 species of mycorrhizal bolete fungi separated from ''Boletus''. Its best known member is the bitter bolete (''Tylopilus felleus''), the only species found in Europe. More species are found in North America, such as the edible species '' T. alboater''. Australia is another continent where many species are found. All members of the genus form mycorrhizal relationships with trees. Members of the genus are distinguished by their pinkish pore surfaces.

Taxonomy

The genus was first defined by Petter Adolf Karsten in 1881. The type species, ''Tylopilus felleus'', was originally described in 1788 as a species of ''Boletus'' by French mycologist Pierre Bulliard. ''Tylopilus'' means "bumpy or swollen pileus", from the Greek ''tylos'' "bump" and ''pilos'' "hat".

Molecular analysis indicates the genus, like other large genera within the Boletales, is polyphyletic. A lineage of ''Tylopilus chromapes'' (now ''Harrya chromapes'' and related species) has been shown to be only distantly related to other members of ''Tylopilus''. Hence ''T. chromapes'' is now the type species of the new genus ''Harrya'' and, related to it, several Australian species moved to ''Australopilus''. ''T. valens'' was also moved to its own genus, ''Pseudoaustroboletus''.

Description

Fruit bodies of the genus ''Tylopilus'' are encountered as large stout bolete mushrooms, which generally arise from the ground or occasionally from wood. They have stout stipes, which do not have a ring. A key field character which distinguishes them from members of the genus ''Boletus'' is the presence of their pink-tinged pores (though these may be white when young). The "pink pore" feature is a polyphyletic morphology that does not unite the ''Tylopilus'' species using traditional morphological characters (Smith and Thiers or Singer's concepts). The spore print manifests various shades of pinkish-brown, through reddish-brown and even chocolate brown.

Edibility

Many species have a bitter taste and are thus inedible, taste being a key feature in identification of this genus. The black velvet bolete ('' T. alboater'') is a good edible, but is often ignored.

Species

, Index Fungorum lists 111 valid species of ''Tylopilus''. About 40 are found in western North America. A large number have been recorded from Australia, with 26 aligned with existing taxa and another 15 not assignable. Members of the genus are also abundant in South America, particularly in forests with trees of the genus ''Dicymbe'' in Guyana, as well as Central America and elsewhere across tropical regions around the world. All are mycorrhizal.
