The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft to very tough. Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures. Many species are brackets, but others have a definite stipe – for example, Polyporus badius.
Bothia is a fungal genus in the family Boletaceae. A monotypic genus, it contains the single species Bothia castanella, a bolete mushroom first described scientifically in 1900 from collections made in New Jersey. Found in the eastern United States, Costa Rica, China, and Taiwan, it grows in a mycorrhizal association with oak trees. Its fruit body is chestnut brown, the cap is smooth and dry, and the underside of the cap has radially elongated tubes. The spore deposit is yellow-brown. The edibility of the mushroom is unknown. Historically, its unique combination of morphological features resulted in the transfer of B. castanella to six different Boletaceae genera. Molecular phylogenetic analysis, published in 2007, demonstrated that the species was genetically unique enough to warrant placement in its own genus.
Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the Boletaceae mushroom family. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots.
Amauroderma is a genus of polypore fungi in the family Ganodermataceae. The genus, widespread in tropical areas, contains about 70 species. Amauroderma fungi are wood-decay fungi that feed and fruit on decayed branches and trunks.
Grammothele is a genus of poroid crust fungi in the family Polyporaceae.
Grammothelopsis is a fungal genus in the family Polyporaceae. It was circumscribed in 1982 by Swiss mycologist Walter Jülich, with Grammothelopsis macrospora as the type species.
Microporellus is a genus of poroid fungi in the family Polyporaceae.
Nigroporus is a genus of poroid fungi in the family Steccherinaceae. The genus was circumscribed by American mycologist William Alphonso Murrill in 1905. Nigroporus has a pantropical distribution. The genus name combines the Latin word niger ("black") with the Ancient Greek word πόρος ("pore").
Tylopilus plumbeoviolaceus, commonly known as the violet-grey bolete, is a fungus of the bolete family. First described in 1936, the mushroom has a disjunct distribution, and is distributed in eastern North America and Korea. The fruit bodies of the fungus are violet when young, but fade into a chocolate brown color when mature. They are solid and relatively large—cap diameter up to 15 cm (5.9 in), with a white pore surface that later turns pink, and a white mycelium at the base of the stem. The mushroom is inedible. A number of natural products have been identified from the fruit bodies, including unique chemical derivatives of ergosterol, a fungal sterol.
Boletellus chrysenteroides is a species of fungus in the family Boletaceae. It was first described as Boletus chrysenteroides by mycologist Wally Snell in 1936. Snell later (1941) transferred the species to Boletellus.
Suillus ochraceoroseus, commonly known as the rosey larch bolete, is a species of mushroom in the genus Suillus. It appears with larch in early summer, is edible, and similar in appearance to S. lakei.
Boletus flammans is a species of bolete fungus found in North America. It was described scientifically by Esther A. Dick and Wally Snell in 1965. As of 2011, its edibility remained unknown.
Boletus curtisii is a species of fungus in the family Boletaceae. It produces small- to medium-sized fruit bodies (mushrooms) with a convex cap up to 9.5 cm (3.7 in) wide atop a slender stem that can reach a length of 12 cm (4.7 in). In young specimens, the cap and stem are bright golden yellow, although the color dulls to brownish when old. Both the stem and cap are slimy or sticky when young. On the underside of the cap are small circular to angular pores. The mushroom is edible, but not appealing. It is found in eastern and southern North America, where it grows in a mycorrhizal association with hardwood and conifer trees. Once classified as a species of Pulveroboletus, the yellow color of B. curtisii is a result of pigments chemically distinct from those responsible for the yellow coloring of Pulveroboletus.
Tylopilus peralbidus is a bolete fungus in the family Boletaceae native to the eastern United States.
Gyroporus purpurinus is a species of bolete fungus in the family Gyroporaceae. Found in eastern North America, it was first described in 1936 by Wally Snell as a form of Boletus castaneus. Snell and Rolf Singer transferred it to Gyroporus a decade later. Neither of these publications were valid according to the rules of botanical nomenclature, which at the time mandated a description in Latin. In 2013, Roy Halling and Naveed Davoodian published the name validly.
Caloboletus frustosus is a bolete fungus native to North America. Until 2014, it was known as Boletus frustosus. Recent changes in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. It was first described scientifically in 1941 by mycologists Wally Snell and Esther Dick.
Xanthoconium purpureum is a species of bolete fungus in the genus Xanthoconium. It was described as new to science in 1962 by Wally Snell and Esther Dick in 1962. It is found in eastern North America, where it fruits under oak, sometimes in oak-pine forests.
Gyrodon tennesseensis is a bolete fungus in the family Paxillaceae. It was originally described in 1940 by Wally Snell and Alexander H. Smith as a species of Boletus. Snell and Hesler transferred it to Gyrodon a year later. It is found in the United States and Canada.
Leccinum brunneo-olivaceum is a species of bolete fungus in the family Boletaceae. It was described as new to science in 1951 by Wally Snell, Ester Dick, and Lexemuel Ray Hesler. The type collection was made in Great Smoky Mountains National Park in Tennessee.
Amyloporia is a genus of five species of crust fungi in the family Polyporaceae. Its main distinguishing characteristic is the amyloid reaction of the skeletal hyphae, although some authors do not consider this to be sufficient to distinguish Amyloporia from the related genus Antrodia.
