The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.
Exsudoporus frostii, commonly known as Frost's bolete or the apple bolete, is a bolete fungus first described scientifically in 1874. A member of the family Boletaceae, the mushrooms produced by the fungus have tubes and pores instead of gills on the underside of their caps. Exsudoporus frostii is distributed in the eastern United States from Maine to Georgia, and in the southwest from Arizona extending south to Mexico and Costa Rica. A mycorrhizal species, its fruit bodies are typically found growing near hardwood trees, especially oak.
Caloboletus rubripes, commonly known as the red-stipe bolete or the red-stemmed bitter bolete, is a mushroom in the family Boletaceae. It was known as Boletus rubripes until 2014. Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged. and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.
Suillus pseudobrevipes is a species of edible mushroom in the genus Suillus. It was first described scientifically by American mycologists Harry D. Thiers and Alexander H. Smith in 1964. This fungal species have a distinctive fibrillous annulus. Compare with Suillus brevipes.
Exsudoporus floridanus is a species of edible bolete mushroom in the family Boletaceae. In 1945, American mycologist Rolf Singer described a species he found in Florida during his 1942–3 tenure of a Guggenheim Memorial Fellowship. He originally described it as a subspecies of the eastern North American species Boletus frostii, but later considered it worthy of distinct species status in a 1947 publication. Based on morphological and phylogenetic data, Vizzini and colleagues transferred this species to a newly described genus Exsudoporus in 2014. Due to lack of sufficient sequences, Wu et al. (2016) were reluctant to accept Exsudoporus and considered it a synonym of Butyriboletus, so they proposed a new combination Butyriboletus floridanus. However, following phylogenetic and morphological analyses clearly resolved Exsudoporus as a monophyletic, homogenous and independent genus that is sister to Butyriboletus.
Tylopilus badiceps is a bolete fungus in the family Boletaceae native to North America. It was described in 1900 as Boletus badiceps by Charles Horton Peck, and transferred to the genus Tylopilus in 1971 by Alexander H. Smith and Harry Delbert Thiers. It is a good edible mushroom.
Chalciporus pseudorubinellus is a bolete fungus of the family Boletaceae. It is found in North America and Central America.
Caloboletus inedulis is a bolete fungus of the family Boletaceae that is native to North America. Until 2014, it was known as Boletus inedulis. Recent changes in the phylogenetic framework of the Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. The species is inedible.
Caloboletus firmus is a bolete fungus native to North America. Until 2014, it was known as Boletus firmus. 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 1874 by American botanist Charles Christopher Frost from specimens collected in New England.
Lanmaoa carminipes is a fungus of the family Boletaceae native to the United States. First described officially in 1971 by mycologists Alexander H. Smith and Harry Delbert Thiers as a species of Boletus, it was transferred to the newly circumscribed genus Lanmaoa in 2015.
Butyriboletus peckii is a fungus of the genus Butyriboletus native to eastern North America. It was first described by Charles Christopher Frost in 1878. Until 2014, it was known as Boletus peckii. Recent changes in the phylogenetic framework of the Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. In 2015, Kuan Zhao and colleagues published analysis that demonstrated that the bolete belongs to Butyriboletus, closely related to Butyriboletus pulchriceps.
Lanmaoa is a fungal genus in the family Boletaceae. It was circumscribed by Chinese mycologists Nian-Kai Zeng and Zhu L. Yang in 2015 to contain several species formerly classified in the genus Boletus, as well as the newly described Asian boletes L. angustispora and L. asiatica. The erection of this genus follows recent molecular studies that outlined a new phylogenetic framework for the family Boletaceae. Zeng and Yang named the genus after Chinese naturalist Lan Mao (1397-1476).
Neoboletus is a genus of fungi in the family Boletaceae, native to holarctic regions. It was circumscribed in 2014 by Italian mycologists Matteo Gelardi, Giampaolo Simonini and Alfredo Vizzini, and further by Chinese mycologists Gang Wu and Zhu L. Yang in 2015. Closely related to the genus Sutorius, members of this genus differ by staining blue when bruised. They have brown pores and lack a reticulated pattern on their stipes. The erection of Neoboletus follows recent molecular studies that outlined a new phylogenetic framework for the Boletaceae. The type species is Neoboletus luridiformis. Five species were added to the genus by Gelardi and Vizzini in 2014.
Parvixerocomus pseudoaokii is a species of bolete fungus in the family Boletaceae, and the type species of the genus Parvixerocomus. It was described by Chinese mycologists Gang Wu and Zhu L. Yang in 2015. It is found only in southwestern, southeastern and southern China, where it grows in subtropical forests with trees of the family Fagaceae, and in mixed forests with Fagaceae and Chinese red pine. Fruitbodies of the fungus are small, with convex to flattened caps typically measuring 0.8–3 cm (0.3–1.2 in) in diameter. All parts of the bolete stain blue when cut or injured.
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.
Suillus pallidiceps is a species of bolete fungus in the family Suillaceae. It was first described scientifically by American mycologists Alexander H. Smith and Harry D. Thiers in 1964.
Suillus ponderosus is a species of bolete fungus in the family Suillaceae. It was first described scientifically by American mycologists Alexander H. Smith and Harry D. Thiers in 1964.
Suillus acerbus is a species of bolete fungus in the family Suillaceae. It was first described scientifically by American mycologists Alexander H. Smith and Harry D. Thiers in 1964.
Suillus brunnescens is a species of bolete fungus in the family Suillaceae. It was first described scientifically by American mycologists Alexander H. Smith and Harry D. Thiers in 1964.
