Tylopilus is a genus of over 100 species of mycorrhizal bolete fungi separated from Boletus. Its best known member is the bitter bolete, the only species found in Europe. More species are found in North America, such as the edible species T. alboater. Australia is another continent where many species are found. All members of the genus form mycorrhizal relationships with trees. Members of the genus are distinguished by their pinkish pore surfaces.
Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff or tan and typically measure up to 15 cm (6 in) in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring and it may be distinguished from Boletus edulis and other similar species by its unusual pink pores and the prominent dark-brown net-like pattern on its stalk.
Orson Knapp Miller Jr. was an American mycologist. He published numerous papers in mycology and was responsible for the naming of many taxa, as well as being one of the authors erecting the genus Chroogomphus. He described Omphalotus olivascens, several species of Amanita, and the ghoul fungus Hebeloma aminophilum.
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.
Tylopilus tabacinus is a species of bolete fungus in the family Boletaceae. It is characterized by a tawny-brown cap measuring up to 17.5 cm (6.9 in) in diameter, and a reticulated stem up to 16.5 cm (6.5 in) long by 6 cm (2.4 in) thick. A characteristic microscopic feature is the distinctive crystalline substance encrusted on the hyphae in the surface of the cap. The species is known from the eastern United States from Florida north to Rhode Island, and west to Mississippi, and from eastern Mexico. It is a mycorrhizal species, and associates with oak and beech trees.
Tylopilus alboater, called the black velvet bolete, by some, is a bolete fungus in the family Boletaceae. The species is found in North America east of the Rocky Mountains, and in eastern Asia, including China, Japan, Taiwan, and Thailand. A mycorrhizal species, it grows solitarily, scattered, or in groups on the ground usually under deciduous trees, particularly oak, although it has been recorded from deciduous, coniferous, and mixed forests.
Tylopilus atronicotianus, commonly known as the false black velvet bolete, is a bolete fungus in the family Boletaceae. First described scientifically in 1998, it is known only from the eastern United States.
Tylopilus rhoadsiae, commonly known as the pale bitter bolete, is a bolete fungus in the family Boletaceae native to the eastern United States.
Harrya chromapes, commonly known as the yellowfoot bolete or the chrome-footed bolete, is a species of bolete fungus in the family Boletaceae. The bolete is found in eastern North America, Costa Rica, and eastern Asia, where it grows on the ground, in a mycorrhizal association with deciduous and coniferous trees. Fruit bodies have smooth, rose-pink caps that are initially convex before flattening out. The pores on the cap undersurface are white, aging to a pale pink as the spores mature. The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base. The mushrooms are edible but are popular with insects, and so they are often infested with maggots.
Tylopilus sultanii is a bolete fungus found in Pakistan and reported as new to science in 2014. Named after Pakistani mycologist Sultan Ahmad (1910–1983), it is one of three Tylopilus species found in the country; the others are T. pseudoscaber and T. felleus. Tylopilus sultanii resembles T. pseudoscaber, but differs from that species in having a cracked cap surface, no color changes in bruised flesh, and larger spores. Known only from the type locality of Ayubia National Park in Khyber Pakhtunkhwa province, it fruits under conifers from July to September.
Tylopilus virens is a bolete fungus in the family Boletaceae found in Asia. It was described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; Japanese mycologist Tsuguo Hongo transferred it to Tylopilus in 1964. The fruit body has a convex to flattened cap that is 2.5–8 cm (1.0–3.1 in) in diameter. The tubes on the cap underside are up to 2 cm long, while the roundish pores are about 1–2 mm wide. The mushroom is similar in appearance to Tylopilus felleus, but unlike that species, has a greenish cap when young. T. virens typically grows near the conifer species Keteleeria evelyniana. It has elliptical spores measuring 11–14 by 5.5–6 µm.
Tylopilus albofarinaceus is a bolete fungus in the family Boletaceae found in China. It was first described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; F.L. Tai transferred it to the genus Tylopilus in 1979. The fruit body has a convex, white cap that is up to 5 cm (2 in) in diameter. The tubes on the cap underside are 3 mm long, while the pores are about 0.7–1 mm wide. The flesh in the stipe is white and does not change color with injury. It has ellipsoid spores measuring 11–14 by 5–7 µm. The type collection was made in Kunming in August 1938.
Tylopilus punctatofumosus is a bolete fungus in the family Boletaceae found in China. It was described as new to science in 1948 by Wei-Fan Chiu as a species of Boletus; F.L. Tai transferred it to the genus Tylopilus in 1979. The fruit body has a hemispherical to cushion-shaped, white cap measuring 2–3.5 cm (0.8–1.4 in) in diameter. The pores on the cap underside measure less than 1 mm wide. The flesh in the stipe is whitish to yellowish at the base, and does not change color with injury. It has ellipsoid spores measuring 9–11 by 5–6 µm. The type collection was made in Chichushan, in September 1938 growing under the conifer species Chinese white pine. Related Asian Tylopilus species include T. javanicus and T. roseolus.
Tylopilus bulbosus is a bolete fungus of the genus Tylopilus. Described as new to science in 2001 by mycologists Roy Halling and Greg Mueller, it is found in Costa Rica, where it grows on the ground in montane forests dominated by the oak species Quercus copeyensis, Q. oocarpa, and Q. seemannii. The fungus produces fruit bodies with convex to flattened caps measuring 4.5–11 cm (1.8–4.3 in) in diameter. Its color is initially violet to purplish brown, and eventually fades to brown. The pore surface is initially pale pinkish purple to grayish red, and bruises brown where it has been handled. The white flesh stains pinkish brown where it has been exposed. Spores are more or less spindle shaped (subfusoid), smooth, and measure 10–14 by 4.2–5.6 µm; the fresh spore deposit is pinkish. Morphologically similar Tylopilus species include the eastern North American T. rubrobrunneus and the North and Central American T. williamsii.
Tylopilus nebulosus is a species of bolete fungus in the family Boletaceae found in eastern North America. It was originally described by Charles Horton Peck in 1898 as a species of Boletus, from collections made in Ray Brook, New York. Carl B. Wolfe transferred it to the genus Tylopilus in 1980.
Tylopilus temucensis is a bolete fungus in the family Boletaceae. Described as new to science in 2005, it is found in central southern Chile, where it grows on the ground in leaf litter under Nothofagus obliqua. It is the first species of Tylopilus reported from Nothofagus forest in South America. The specific name temucensis refers to Temuco, near the type locality. Fruit bodies have hemispherical to convex brownish caps measuring 3.5–13 cm (1.4–5.1 in) in diameter. The roundish pores on the cap underside are pale yellow, numbering about 1–2 per mm, while the tubes are 6–8 mm long. The fresh spore print is dark pink to purplish gray. Spores are smooth, ellipsoid to fusiform (spindle-shaped), and typically measure 33–43 by 4–8 µm.
Sutorius eximius, commonly known as the lilac-brown bolete, is a species of fungus in the family Boletaceae. This bolete produces fruit bodies that are dark purple to chocolate brown in color with a smooth cap, a finely scaly stipe, and a reddish-brown spore print. The tiny pores on the cap underside are chocolate to violet brown. It is widely distributed, having been recorded on North America, South America, and Asia, where it grows in a mycorrhizal relationship with both coniferous and deciduous trees.
Pseudoaustroboletus is a fungal genus in the family Boletaceae. The genus is monotypic, containing the single species Pseudoaustroboletus valens, found in China, Japan, Malaysia and Singapore. It was originally given the name Boletus albellus illegitimately based on specimens from Singapore by George Edward Massee in 1909. In 1972 it was given the name Boletus valens legitimately before being transferred to Tylopilus valens in 1976. A molecular phylogenetics study found it to be distinct from Tylopilus and Boletus and the authors placed it in its own genus, Pseudoaustroboletus.
Tylopilus glutinosus is a species of the fungal family Boletaceae. It is the first generic report for Bangladesh. This species is putatively associated with Shorea robusta.
