Suillus punctipes, commonly known as the spicy suillus, is a bolete fungus in the family Suillaceae.
The fungus was originally described in 1878 by American mycologist Charles Horton Peck as a species of Boletus . Collected from Gansevoort, New York, Peck described its distinguishing features as "its rhubarb-colored stem thickened at the base and the brownish color of the young hymenium". [3] Rolf Singer transferred it to Suillus in 1945. [4]
The bolete has been recorded from Taiwan. [5]
Suillus is a genus of basidiomycete fungi in the family Suillaceae and order Boletales. Species in the genus are associated with trees in the pine family (Pinaceae), and are mostly distributed in temperate locations in the Northern Hemisphere, although some species have been introduced to the Southern Hemisphere.
Suillus luteus is a bolete fungus, and the type species of the genus Suillus. A common fungus native all across Eurasia from Ireland to Korea, it has been introduced widely elsewhere, including North and South America, southern Africa, Australia and New Zealand. Commonly referred to as slippery jack or sticky bun in English-speaking countries, its names refer to the brown cap, which is characteristically slimy in wet conditions. The fungus, initially described as Boletus luteus by Carl Linnaeus in 1753, is now classified in a different fungus family as well as genus. Suillus luteus is edible, though not as highly regarded as other bolete mushrooms. It is commonly prepared and eaten in soups, stews or fried dishes. The slime coating, however, may cause indigestion if not removed before eating. It is often sold as a dried mushroom.
Suillus bovinus, also known as the Jersey cow mushroom or bovine bolete, is a pored mushroom of the genus Suillus in the family Suillaceae. A common fungus native to Europe and Asia, it has been introduced to North America and Australia. It was initially described as Boletus bovinus by Carl Linnaeus in 1753, and given its current binomial name by Henri François Anne de Roussel in 1806. It is an edible mushroom, though not highly regarded.
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.
Suillus americanus is a species of fungus in the mushroom family Suillaceae. Commonly known as the chicken fat mushroom, American suillus, it grows in a mycorrhizal association with eastern white pine and is found where this tree occurs in eastern North America and China. The mushroom can be recognized by the bright yellow cap with red to reddish-brown scales embedded in slime, the large yellow angular pores on the underside of the cap, and the narrow yellow stem marked with dark reddish dots. Molecular phylogenetics analysis suggests that S. americanus may be the same species as S. sibiricus, found in western North America and western and central Asia. Suillus americanus is edible, although opinions vary as to its palatability; some susceptible individuals may suffer a contact dermatitis after touching the fruit bodies. The fruit bodies contain a beta glucan carbohydrate shown in laboratory tests to have anti-inflammatory properties.
Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm, while the stipe is up to 6 cm long and 2 cm thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.
Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the family Suillaceae. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm, while the stems are between 6 and 12 cm long and usually 1–3 cm thick. On the underside of the cap is a layer of spongy yellow to yellow-brown angular pores; these pores are covered with a whitish partial veil when young. A mycorrhizal fungus, S. lakei grows in association with Douglas fir, and is found where this tree occurs. It is native to northwestern North America, but has been introduced to Europe, South America, and New Zealand. The mushroom is edible, but opinions vary considerably as to its quality.
Suillus spraguei is a species of fungus in the family Suillaceae. It is known by a variety of common names, including the painted slipperycap, the painted suillus or the red and yellow suillus. Suillus spraguei has had a complex taxonomical history, and is also frequently referred to as Suillus pictus in the literature. The readily identifiable fruit bodies have caps that are dark red when fresh, dry to the touch, and covered with mats of hairs and scales that are separated by yellow cracks. On the underside of the cap are small, yellow, angular pores that become brownish as the mushroom ages. The stalk bears a grayish cottony ring, and is typically covered with soft hairs or scales.
Suillus sibiricus is a fungus of the genus Suillus in the family Suillaceae. It is found in mountains of Europe, North America, and Siberia, strictly associated with several species of pine tree. Due to its specific habitat and rarity in Europe, it has been selected for inclusion in several regional Red Lists. Its fruit bodies are characterised by having slimy caps in wet weather, which can reach diameters of up to 10 cm (3.9 in). On the underside of the cap are yellow angular pores that bruise a pinkish to cinnamon colour. The stem is up to 8 cm (3.1 in) tall and 2.5 cm (1.0 in) wide and typically has a ring, a remnant of the partial veil that covers the fruit body in its early development. In North America, it is commonly called the Siberian slippery jack. Phylogenetic analysis has shown that S. sibiricus is closely related to S. umbonatus and S. americanus, and may in fact be conspecific with the latter species.
Suillus decipiens is an edible species of mushroom in the family Suillaceae. First described by Charles Horton Peck in 1889 as Boletinus decipiens, it was transferred to Suillus in 1898 by Otto Kuntze. The fungus is found in southeastern North America, with the northern limit of its range extending to New Jersey.
Suillus cothurnatus is a species of mushroom in the genus Suillus. Found in Malaysia, Brazil, and North America, it was first described scientifically by mycologist Rolf Singer in 1945.
Suillus salmonicolor, commonly known as the Slippery Jill, is a fungus in the family Suillaceae of the order Boletales. First described as a member of the genus Boletus in 1874, the species acquired several synonyms, including Suillus pinorigidus and Suillus subluteus, before it was assigned its current binomial name in 1983. It has not been determined with certainty whether S. salmonicolor is distinct from the species S. cothurnatus, described by Rolf Singer in 1945. S. salmonicolor is a mycorrhizal fungus—meaning it forms a symbiotic association with the roots of plants such that both organisms benefit from the exchange of nutrients. This symbiosis occurs with various species of pine, and the fruit bodies of the fungus appear scattered or in groups on the ground near the trees. The fungus is found in North America, Hawaii, Asia, the Caribbean, South Africa, Australia and Central America. It has been introduced to several of those locations via transplanted 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.
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.
Boletus auripes, commonly known as the butter-foot bolete, is a species of bolete fungus in the family Boletaceae. First described from New York in 1898, the fungus is found in eastern Asia, Central America, and eastern North America from Canada to Florida. It is a mycorrhizal species and typically grows in association with oak and beech trees.
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.
Boletus subvelutipes, commonly known as the red-mouth bolete, is a bolete fungus in the family Boletaceae. It is found in Asia and North America, where it fruits on the ground in a mycorrhizal association with both deciduous and coniferous trees. Its fruit bodies (mushrooms) have a brown to reddish-brown cap, bright yellow cap flesh, and a stem covered by furfuraceous to punctate ornamentation and dark red hairs at the base. Its flesh instantly stains blue when cut, but slowly fades to white. The fruit bodies are poisonous, and produce symptoms of gastrointestinal distress if consumed.
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.
Leccinellum rugosiceps, commonly known as the wrinkled Leccinum, is a species of bolete fungus. It is found in Asia, North America, Central America, and South America, where it grows in an ectomycorrhizal association with oak. Fruitbodies have convex, yellowish caps up to 15 cm (5.9 in) in diameter. In age, the cap surface becomes wrinkled, often revealing white cracks. The stipe is up to 10 cm (3.9 in) long and 3 cm (1.2 in) wide, with brown scabers on an underlying yellowish surface. It has firm flesh that stains initially pinkish to reddish and then to grayish or blackish when injured. The pore surface on the cap underside is yellowish. Fruitbodies are edible, although opinions vary as to their desirability.
Suillus subaureus is a rare species of bolete fungus in the family Suillaceae. It is found in North America, where it associates with deciduous trees. Originally described in 1887 by Charles Horton Peck, it was transferred to genus Suillus by Wally Snell in 1944. Fruitbodies are pale yellow—reflecting its specific epithet subaureus, which means "somewhat golden yellow". The spore print is olive brown. Spores are smooth and inamyloid, and measure 7–10 by 2.7–3.5 µm. It has also been recorded in Taiwan.
