Boletus curtisii is a species of
Taxonomy
The species was first described scientifically by English mycologist Miles Joseph Berkeley in 1853.[2] The specific epithet curtisii honors Moses Ashley Curtis,[3] who collected the type material from South Carolina.[2]
American mycologist William Murrill called it Ceriomyces curtisii in 1909,[4] but Ceriomyces (as defined by Murrill in 1909) has since been subsumed into Boletus.[5] In his 1947 monograph on boletes of Florida, Rolf Singer transferred the species to the genus Pulveroboletus, and made it the type of his newly described section Cartilaginei, which featured species with a glutinous or sticky stem, and a leather-colored to brownish hymenophore.[6] Species in Pulveroboletus are characterized by the presence of pigments based on the chemical structure of pulvinic acid, a yellow-orange compound found in some species of Boletales.[7] The pigments responsible for the color of B. curtisii are, however, entirely different from the pulvinic acid compounds found in Pulveroboletus species, which invalidates the chemotaxonomical rational for generic placement in Pulveroboletus.[8] Otto Kuntze once placed the species in Suillus, but it lacks the partial veil and glandular dots associated with that genus.[9] William Chambers Coker and Alma Beers considered Charles Horton Peck's Boletus inflexus (described from New York in 1895[10]) as well as Henry Curtis Beardslee's 1915 B. carolinensis to be the same species as B. curtisii.[11] Coker and Beer's suggested synonymy, however, is not recognized by the taxonomical authorities MycoBank or Index Fungorum.[1][12]
Wally Snell once considered Boletus carolinensis to be the same species as B. curtisii. He claimed that the former species was then considered distinct from the latter by virtue of an even, instead of reticulate (netlike) stem, although they were otherwise quite similar in appearance and spore size and shape.[13] Snell explained that although neither the English nor the Latin text of Berkeley's original description mentioned a reticulated stem, a later (1872) description by Berkeley characterized the stem as reticulato.[14] Snell thought that this might have been an error in transcription, or an error in the species account, as herbarium specimens that he had examined lacked this feature.[13] He changed his mind a couple of years later, when he found a small amount of reticulation in material collected by Peck.[15]

The
The stem is 6–12 cm (2.4–4.7 in) long, 0.6–1.3 cm (0.2–0.5 in) thick, and roughly equal in width throughout. Its surface is sticky and glutinous when fresh, somewhat scurfy near the apex (covered with loose scales) but smooth below. It is pale yellow to yellow down to the base, which is sheathed with a cottony white mycelium. The stem can be either solid or hollow. The mushroom lacks a partial veil and a ring. The spore print is olive-brown.[16] The mushroom is edible, but not appealing.[3]

Similar species
Retiboletus retipes is somewhat similar in appearance, but is distinguished by a more orange to orange-yellow color, a lack of sliminess, and a distinctly reticulated stalk.[3]
