Rubroboletus satanas, commonly known as Satan's bolete or the Devil's bolete, is a basidiomycete fungus of the bolete family (Boletaceae) and one of its most infamous members. It was known as Boletus satanas before its transfer to the new genus Rubroboletus in 2014, based on molecular phylogenetic data. These squat, brightly coloured fruiting bodies are often massive and imposing, with a beige-coloured velvet-textured cap up to 50 cm (20 in) across, yellow to orange-red pores and a bulbous red stem. The flesh turns blue when cut or bruised and the fruit bodies often emit an unpleasant rotten

Rubroboletus rhodoxanthus is a species of bolete in the family Boletaceae, native to Europe. Previously known as Boletus rhodoxanthus, it was transferred in 2014 to the newly erected genus Rubroboletus, based on DNA data. It produces large, colourful fruit bodies with pink patches on the cap, red pores in the hymenial surface and has a robust stem decorated in a dense, red-coloured network pattern. When longitudinally sliced, its flesh is distinctly bright yellow in the stem and discolours blue only in the cap, an excellent diagnostic feature distinguishing it from similar species. The fungus

Rubroboletus is a genus of bolete fungi in the family Boletaceae. It was circumscribed by Chinese mycologists in 2014 with Rubroboletus sinicus as the type species. Species are characterized by having a reddish cap surface, yellow tubes on the underside of the cap, and an orange-red to blood-red pore surface. Pinkish to red spots (reticula) are present on the stipe surface, and a bluish color change occurs when the bolete flesh is injured. Rubroboletus mushrooms have an olive-brown spore print, and produce smooth spores. Eight species were included in the original circumscription (seven new

Rubroboletus dupainii, commonly known as Dupain's bolete, is a bolete fungus of the genus Rubroboletus. It is native to Europe, where it is threatened, and red listed in six countries. It also occurs in North America, although it is rare there. It was first recorded from North Carolina, and then from Iowa in 2009. It was reported from Belize in 2007, growing under Quercus peduncularis - a species of oak tree. The bolete was first described scientifically by French mycologist Jean Louis Émile Boudier in 1902. It was transferred to the new genus Rubroboletus in 2014 along with several other

Exsudoporus frostii (formerly Boletus 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. It can be recognized by its dark red sticky caps, the red pores, the network-like pattern of the stipe, and the bluing reaction to tissue injury. Another characteristic of young, moist fruit bodies is the amber-colored drops exuded on the pore surface. The species is distributed in the eastern

Rubroboletus rubrosanguineus is a species of bolete fungus in the family Boletaceae that is found in Europe.

Rubroboletus pulchrotinctus is a rare bolete fungus in the genus Rubroboletus, native to central and southern Europe. It was originally described in genus Boletus by Italian mycologist Carlo Luciano Alessio in 1985, but subsequently transferred to genus Rubroboletus by Zhao and colleagues (2015), on the basis of molecular evidence. Phylogenetically, R. pulchrotinctus is the sister-species of the better known Rubroboletus satanas, with which it shares several morphological features. Rubroboletus pulchrotinctus forms ectomycorrhizal associations with several members of the Fagaceae,

Rubroboletus sinicus is a bolete fungus in the family Boletaceae. It is found in China. The species was first described by Wei Fan Chiu as Boletus sinicus in 1948 and transferred to the genus Tylopilus in 1979 by Fanglan Tai. In 2014, the genus Rubroboletus was created to accommodate this and allied species. The fruit bodies of R. sinicus` have a brown, pulvinate (cushion-shaped) cap measuring 9–11 cm (3.5–4.3 in), covered with fibrous scales. The tubes on the cap underside are up to 4 mm (0.16 in) long, and stain blue when cut or injured. The pores are red and small, up to 0.5 mm across. The

Rubroboletus rhodosanguineus is a fungus of the genus Rubroboletus native to North America. It was described scientifically by mycologist Ernst Both in 1998. It was transferred from Boletus to the new genus Rubroboletus in 2014, along with several other allied reddish colored, blue-staining bolete species.

Butyriboletus pulchriceps is a fungus of the family Boletaceae native to North America. It was first formally described in 2000, as a member of the genus Boletus, and transferred to Butyriboletus 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.

Rubroboletus latisporus is a bolete fungus in the family Boletaceae. It is found in Yunnan province in southwestern China, associated with Pinus massoniana and Quercus trees.

Butyriboletus roseopurpureus is a species of fungus in the family Boletaceae. Found in eastern North America, it was officially described in 2000 as a species of Boletus, and transferred to the genus Butyriboletus in 2015.

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.

Pulveroboletus sinensis is a species of blue staining bolete fungus of the family Boletaceae and the genus Pulveroboletus found in the Guangdong Province in China. It is characterized by its yellow to vivid-yellow pulverulent cap which can darken to a deep orange at the center, and is covered with deep-orange to brown-orange conico-pyramidal scales. The cap is cyanescent when cut or bruised, while the stem does not stain. These scales distinguish P. sinensis from a closely related species Pulveroboletus brunneopunctatus. Singular fruiting bodies form from July to October on soil, underneath

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 (Pinus massoniana). 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 yunnanensis is a bolete fungus native to Yunnan province in China, where it grows under Pinus yunnanensis.
