Suillus intermedius is an edible species of mushroom in the genus Suillus . [2] It is found in North America, Costa Blanca Mountains-Spain. [3]
In mycology, a partial veil is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present.
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.
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 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.
Caloboletus rubripes, commonly known as the red-stipe bolete or the red-stemmed bitter bolete, is a mushroom in the family Boletaceae. It was known as Boletus rubripes until 2014. Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged. and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.
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 subalutaceus is an edible species of mushroom in the genus Suillus. It is found in North America and in Taiwan.
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 cavipes is an edible species of mushroom in the genus Suillus. It is found in Europe and North America. It is associated with larch in the Pacific Northwest.
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.
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.
Chalciporus pseudorubinellus is a bolete fungus of the family Boletaceae. It is found in North America and Central America.
Boletus subluridellus is a species of bolete fungus in the family Boletaceae. Described as new to science in 1971 by American mycologists, the bolete is found in the eastern United States and Canada. It grows on the ground in coniferous and mixed forests in a mycorrhizal association with deciduous trees, especially oak. The fruit bodies (mushrooms) have orangish-red, broadly convex caps that are up to 10 cm (3.9 in) in diameter, with small, dark reddish pores on the underside. The pale yellow stipe measures 4–9 cm (1.6–3.5 in) long by 1.5–2.3 cm (0.6–0.9 in) thick. All parts of the fruit body will quickly stain blue when injured or touched.
Tylopilus intermedius, commonly known as the bitter parchment bolete, is a bolete fungus in the family Boletaceae native to the eastern United States.
Leccinum insigne, commonly known as the aspen bolete or the aspen scaber stalk, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1966, it is found in North America, where its range extends from eastern Canada south to New Jersey and west to the northern Rocky Mountains. It is a good edible mushroom, but there have been documented cases of adverse reactions; these range from headaches to gastrointestinal distress, which may or may not be attributed to food sensitivities alone. The specific epithet insigne means "distinctive or outstanding".
Suillus serotinus is a species of bolete fungus found in eastern North America. Originally described as a species of Boletus by American botanist Charles Christopher Frost in 1874, it was transferred to Suillus in 1996. The bolete has a dark red brown and sticky cap up to 12 cm (4.7 in) in diameter. The pore surface is initially white before turning reddish brown in age; the angular pores number from 1 to 3 per millimeter. Mushroom flesh slowly stains bluish after injury, later becoming purplish gray then finally reddish brown. The fungus grows in a mycorrhizal association with larch and fruits on the ground scattered or in groups. The spore print is purplish brown; spores are oblong to ellipsoid, smooth, and measure 8–12 by 4–5 µm. The fruit bodies are edible, but lack any distinctive taste or odor.
Tylopilus sordidus is a bolete fungus in the family Boletaceae. It was originally described in 1874 by Charles Christopher Frost as a species of Boletus. Alexander H. Smith and Harry Thiers transferred it to the genus Tylopilus in 1968. Fruit bodies of the fungus have a convex to flattened cap measuring 4.5–13 cm (1.8–5.1 in) in diameter. The brownish cap surface is initially tomentose to felt-like, but develops cracks in age. All parts of the mushrooms bruise dark blue to greenish when injured. The spore print is reddish brown; spores are smooth, roughly elliptical, and measure 10–14 by 4–6 µm. The bolete is found in North America, where it grows on the ground under oaks and conifers. Its edibility was recently unknown, but it is now considered inedible.
Suillus borealis is a species of bolete fungus in the family Suillaceae. Found in western North America where it associates with western white pine, 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.
