Suillus borealis | |
Suillus borealis is a species of bolete fungus in the family Suillaceae. Found in western North America where it associates with western white pine (Pinus monticola), the fungus was described as new to science in 1965 by mycologists Alexander H. Smith, Harry Delbert Thiers, and Orson K. Miller. It is similar in appearance to Suillus luteus , but unlike in that species, the partial veil does not form a ring on the stipe. [1]
The species is considered to be an excellent edible mushroom. [2]
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.
Alexander Hanchett Smith was an American mycologist known for his extensive contributions to the taxonomy and phylogeny of the higher fungi, especially the agarics.
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 pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.
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.
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.
Suillus fuscotomentosus is an edible species of mushroom in the genus Suillus. Found in western North America, it was described as new to science in 1964 by mycologists Harry Delbert Thiers and Alexander H. Smith. It usually grows under three-needle pines, such as ponderosa pine and Monterey pine.
Suillus flavogranulatus is a bolete mushroom in the genus Suillus native to North America. It was described as new to science in 1965 by mycologists Alexander H. Smith, Harry Delbert Thiers, and Orson K. Miller.
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.
