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. Found in broad-leaved and mixed woodland in the warmer regions of Europe, it is classified as a poisonous mushroom, known to cause gastrointestinal symptoms of diarrhea and violent vomiting. However, reports of poisoning are rare, due to its striking appearance and at times putrid smell, which discourage casual experimentation.
Xerocomellus chrysenteron, formerly known as Boletus chrysenteron or Xerocomus chrysenteron, is a small, edible, wild mushroom in the family Boletaceae. These mushrooms have tubes and pores instead of gills beneath their caps. It is commonly known as the red cracking bolete.
Rubroboletus legaliae, previously known as Boletus splendidus, B. satanoides, and B. legaliae is a basidiomycete fungus of the family Boletaceae. It is poisonous, with predominantly gastrointestinal symptoms, and is related to Rubroboletus satanas.
Hortiboletus rubellus, commonly known as the ruby bolete, is a small, dainty, brightly coloured member of the family Boletaceae, with a reddish cap and stipe, and yellow pores. Like many boletes, it stains blue when cut or bruised. It is found in deciduous woodland in autumn. There is some question over its edibility, and it is reportedly of poor quality with a taste of soap. Until 2015, the species was known as Boletus rubellus.
Gyrodon lividus, commonly known as the alder bolete, is a pored mushroom bearing close affinity to the genus Paxillus. Although found predominantly in Europe, where it grows in a mycorrhizal association with alder, it has also recorded from China, Japan and California. Fruit bodies are distinguished from other boletes by decurrent bright yellow pores that turn blue-grey on bruising. G. lividus mushrooms are edible.
Gyroporus castaneus, or commonly the chestnut bolete, is a small, white-pored relation of the Boletus mushrooms. It has a brown cap, and is usually found with oak trees. It differs from the true boletes in that the spores are a pale straw colour.
Xerocomus subtomentosus, commonly known as suede bolete, brown and yellow bolete , boring brown bolete or yellow-cracked bolete, is a species of bolete fungus in the family Boletaceae. The fungus was initially described by Carl Linnaeus in 1753 and known for many years as Boletus subtomentosus. It is edible, though not as highly regarded as other bolete mushrooms.
Boletellus obscurecoccineus, known as the rhubarb bolete, is a species of fungus in the family Boletaceae, found in Australia, New Guinea, Java, Borneo, Japan, Korea, and Taiwan. It is a distinctive and colourful bolete of the forest floor.
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.
Xerocomellus zelleri, commonly known as Zeller's bolete, is an edible species of mushroom in the family Boletaceae. First described scientifically by American mycologist William Alphonso Murrill in 1912, the species has been juggled by various authors to several genera, including Boletus, Boletellus, and Xerocomus. Found solely in western North America from British Columbia south to Mexico, the fruit bodies are distinguished by their dark reddish brown to nearly black caps with uneven surfaces, the yellow pores on the underside of the caps, and the red-streaked yellow stems. The fungus grows in summer and autumn on the ground, often in Douglas fir forests or on their margins. The development of the fruit bodies is gymnocarpic, meaning that the hymenium appears and develops to maturity in an exposed state, not enclosed by any protective membrane.
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.
Oldrose bolete, Imperator rhodopurpureus, is an inedible fungus of the genus Imperator, found under deciduous trees including oak and beech in neutral soils. Initially described as Boletus rhodopurpureus, it was transferred to the new genus Imperator in 2015. The bolete is considered critically endangered in the Czech Republic., and endangered in the United Kingdom, reported most commonly from Berkshire and Hampshire, and typically very rare throughout, although up to a hundred fruiting bodies have been recorded at a few sites.
Butyriboletus regius, commonly known as the royal bolete or red-capped butter bolete, is a basidiomycete fungus of the genus Boletus found in China and Europe. B. regius has a pink cap, yellow flesh, and a reticulate pattern on the stem. Harry D. Thiers described a similar mushroom from California as B. regius, though it is not the same species. B. regius in Europe does not stain when exposed to air, or stains weakly, but the California species stains blue. Both European and California species are considered choice edibles.
Boletus abruptibulbus is a species of bolete mushroom in the family Boletaceae. Described as new to science in 2009, it is found only in the Gulf Coast of the Florida Panhandle, where it grows on the ground in coastal sand dunes, one of only three North American boletes known to favor this habitat. The fruit bodies have convex brownish caps up to 8 cm (3.1 in) in diameter, supported by solid yellowish to reddish stems measuring 3–5 cm (1.2–2.0 in) long by 10–15 mm (0.4–0.6 in) thick. The pores on the underside of the cap measure about 1–2 mm in diameter and are initially pale yellow before developing a greenish tinge in age. The mushroom's spores, about 20 micrometers long, are unusually long for a member of the Boletaceae. The stem base is bulbous, a diagnostic feature for which the species is named.
Aureoboletus auriflammeus, commonly known as the flaming gold bolete, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1872, it is found in eastern North America, where it grows in a mycorrhizal association with oaks. The caps of the fruit bodies are golden orange, with a yellow pore surface on the underside, and a reticulated (network-like) stem. The edibility of the mushroom is not known.
Xerocomus illudens is a species of bolete fungus in the family Boletaceae. Described as new to science in 1898, it is found in Asia and North America, where it grows in a mycorrhizal association with oak.
Xerocomellus is a genus of fungi in the family Boletaceae. The genus, as it was described in 2008, contained 12 species. However X. rubellus and X. engelii were transferred to the new genus Hortiboletus and X. armeniacus was transferred to the new genus Rheubarbariboletus in 2015. Molecular analysis supports the distinction of Xerocomellus species from Boletus and Xerocomus, within which these species were formerly contained. Xerocomellus in fact is only distantly related to Xerocomus and is most closely related to Tylopilus, Boletus sensu stricto, Porphyrellus, Strobilomyces, and Xanthoconium.
Hemileccinum impolitum is a basidiomycete fungus of the family Boletaceae, native to Europe. It is commonly referred to as the iodine bolete, because its fruit bodies tend to emit an iodine odour when cut, more detectable in the stem base or overripe specimens.
Imleria badia, commonly known as the bay bolete, is an edible, pored mushroom found in Eurasia and North America, where it grows in coniferous or mixed woods on the ground or on decaying tree stumps, sometimes in prolific numbers. Both the common and scientific names refer to the bay- or chestnut-coloured cap, which is almost spherical in young specimens before broadening and flattening out to a diameter up to 15 cm (6 in). On the cap underside are small yellowish pores that turn dull blue-grey when bruised. The smooth, cylindrical stipe, measuring 4–9 cm long by 1–2 cm thick, is coloured like the cap, but paler. Some varieties have been described from eastern North America, differing from the main type in both macroscopic and microscopic morphology.
