''Harrya chromapes'', commonly known as the yellowfoot bolete or the chrome-footed bolete, is species of bolete fungus in the family Boletaceae. The bolete is found in eastern North America, Costa Rica, and eastern Asia, where it grows on the ground, in a mycorrhizal association with deciduous and coniferous trees. Fruit bodies have smooth, rose-pink caps that are initially convex before flattening out. The pores on the cap undersurface are white, aging to a pale pink as the spores mature. The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base. The mushrooms are edible but are popular with insects, and so they are often infested with maggots. In its taxonomic history, ''Harrya chromapes'' has been shuffled to several different genera, including ''Boletus'', ''Leccinum'', and ''Tylopilus'', and is known in field guides as a member of one of these genera. In 2012, it was transferred to the newly created genus ''Harrya'' when it was established that morphological and molecular evidence demonstrated its distinctness from the genera in which it had formerly been placed. ==Taxonomy== The species was first described scientifically by American mycologist Charles Christopher Frost as ''Boletus chromapes''. Cataloging the bolete fungi of New England, Frost published 22 new bolete species in that 1874 publication.〔 Rolf Singer placed the species in ''Leccinum'' in 1947 due to the scabrous dots on the stipe,〔 even though the spore print color was not typical of that genus. In 1968, Alexander H. Smith and Harry Delbert Thiers thought that ''Tylopilus'' was a more appropriate fit as they believed the pinkish-brown spore print—characteristic of that genus—to be of greater taxonomic significance.〔 Other genera to which it has been shuffled in its taxonomic history include ''Ceriomyces'' by William Alphonso Murrill in 1909,〔 and ''Krombholzia'' by Rolf Singer in 1942;〔 ''Ceriomyces'' and ''Krombholzia'' have since been subsumed into ''Boletus'' and ''Leccinum'', respectively.〔 Additional synonyms include ''Tylopilus cartagoensis'', described by Wolfe & Bougher in 1993,〔 and a later combination based on this name, ''Leccinum cartagoense''.〔 Molecular analysis of large-subunit ribosomal DNA and translation elongation factor 1α showed that the species belonged to a unique lineage in the family Boletaceae, and the genus ''Harrya'' was circumscribed to contain both it (as the type species) and the newly described ''H. atriceps''. Javan species referred to ''Tylopilus pernanus'' are sister to the ''Harrya'' lineage.〔 The specific epithet ''chromapes'' is Latin for "yellow foot".〔 It is commonly known as the "yellowfoot bolete"〔 or the "chrome-footed bolete".〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Harrya chromapes」の詳細全文を読む スポンサード リンク
