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.
Amanita cokeri, commonly known as Coker's amanita and solitary lepidella, is a mushroom in the family Amanitaceae. The mushroom is poisonous. First described as Lepidella cokeri in 1928, it was transferred to the genus Amanita in 1940.
Agaricus subrutilescens, also known as the wine-colored agaricus, is a mushroom of the genus Agaricus. It was first described scientifically in 1925 as Psalliota subrutilescens, and later transferred to Agaricus in 1938.
Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. It is generally found in beech woodland in summer and autumn. Two subspecies have been described from southern Europe. First officially described by Christiaan Hendrik Persoon in 1801, T. pardinum has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides.
Phallus ravenelii, commonly known as Ravenel's stinkhorn, is a fungus in the Phallaceae (stinkhorn) family. It is found in eastern North America. Its mushrooms commonly grow in large clusters and are noted for their foul odor and phallic shape when mature. It is saprobic, and as such it is encountered in a wide variety of habitats rich in wood debris, from forests to mulched gardens or sawdust piles in urban areas. It appears from August to October. The fruit body emerges from a pink or lavender-colored egg to form a tall, cylindrical, hollow and spongy white stalk with a bell-shaped cap. The remains of the egg persist as a white to pink or lilac volva at the base of the stalk. The cap is covered in a foul-smelling olive-green spore slime, which attracts insects that help to spread the spores. Sometimes, the cap has a "veil" attached—a thin membrane that hangs underneath. The lack of a roughly ridged and pitted cap differentiates it from the closely related Phallus impudicus. The fungus is named after Henry William Ravenel, a botanist who first discovered it in 1846, though it remained undescribed until 1873. It is considered to be an edible mushroom while in its egg form.
Gyromitra caroliniana, known commonly as the Carolina false morel or big red, is an ascomycete fungus of the genus Gyromitra, within the Pezizales group of fungi. It is found in hardwood forests of the southeastern United States, where it fruits in early spring soon after snowmelt.
Grifola frondosa is a polypore mushroom that grows at the base of trees, particularly old growth oaks or maples. It is typically found in late summer to early autumn. It is native to China, Europe, and North America.
Mycena galericulata is a mushroom species commonly known as the common bonnet, the toque mycena, the common mycena or the rosy-gill fairy helmet. The type species of the genus Mycena was first described scientifically in 1772, but was not considered a Mycena until 1821. It is quite variable in color, size, and shape, which makes it somewhat difficult to reliably identify in the field. The mushrooms have caps with distinct radial grooves, particularly at the margin. The cap's color varies from grayish brown to dark brown and the shape ranges from bell-like to bluntly conical to flattened with an umbo. The stem is hollow, white, tough and thin, without a ring and often roots deeply into the wood on which it grows. The gills are white to grayish or even pinkish when mature and are connected by distinct cross-veins. The caps can reach 4 cm (1.6 in) in diameter, and have a mealy odor and taste. The spore print is white and the gills are pink at maturity, which can lead to possible confusion with species of the genus Pluteus. M. galericulata mushrooms grow mostly in clusters on the well-decayed stumps of deciduous and coniferous trees from spring to autumn. The species can generally be considered inedible. It is common and widespread in the entire temperate zone of the Northern Hemisphere, but it has also been reported from Africa.
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.
Mycena overholtsii, commonly known as the snowbank fairy helmet or fuzzy foot, is a species of fungus in the family Mycenaceae. The mushrooms produced by the fungus are relatively large for the genus Mycena, with convex grayish caps up to 5 cm (2 in) in diameter and stems up to 15 cm (6 in) long. The gills on the underside of the cap are whitish to pale gray, and initially closely spaced before becoming well-spaced at maturity after the cap enlarges. The mushrooms are characterized by the dense covering of white "hairs" on the base of the stem. M. overholtsii is an example of a snowbank fungus, growing on well-decayed conifer logs near snowbanks, during or just after snowmelt. Formerly known only from high-elevation areas of western North America, particularly the Rocky Mountain and Cascade regions, it was reported for the first time in Japan in 2010. The edibility of the mushroom is unknown. M. overholtsii can be distinguished from other comparable species by differences in location, or spore size.
Amanita daucipes is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edibility is unknown for the species, but consumption is generally not recommended due its position in the Amanita subgroup Lepidella, which contains some poisonous members.
Amanita onusta, commonly known as the loaded Lepidella, the gunpowder Lepidella or the gunpowder amanita, is a species of fungus in the mushroom family Amanitaceae. It is characterized by its small to medium-sized fruit bodies that have white to pale gray caps crowded with roughly conical, pyramidal, or irregular gray warts. The stipe is whitish-gray with woolly or wart-like veil remnants, and at the base is a spindle- or turnip-shaped base that is rooted somewhat deeply in the soil. The species is distributed in eastern North America, from Nova Scotia to Mexico, and may be found growing on the ground in deciduous forests, particularly those with oak, hickory and chestnut. Fruit bodies smell somewhat like bleaching powder, and their edibility is unknown, but possibly toxic.
Xeromphalina campanella is a species of mushroom. The common names of the species include the golden trumpet and the bell Omphalina. The genus name Xeromphalina means "little dry navel" and campanella means "bell-shaped", respectively describing the mature and young shapes of the pileus, or cap. The mushroom is also called fuzzy-foot.
Lactarius argillaceifolius is a species of fungus in the family Russulaceae. The mushrooms produced by the fungus have convex to flattened drab lilac-colored caps that are up to 18 cm (7.1 in) wide. The cream-colored gills are closely spaced together and extend slightly down the length of the stem, which is up to 9 cm (3.5 in) long by 3.5 cm (1.4 in) thick. The mushroom produces an off-white latex when injured that stains the mushroom tissue brownish.
Coprinopsis variegata, commonly known as the scaly ink cap or the feltscale inky cap, is a species of fungus in the family Psathyrellaceae. Distributed in eastern North America, it has a medium-sized, bell-shaped to flattened cap up to 7.5 cm (3.0 in) in diameter, with felt-like, patchy scales. The gills, initially white, turn black in maturity and eventually dissolve into a black "ink". Fruit bodies grow in clusters or groups on leaf litter or rotted hardwood, although the wood may be buried, giving the appearance of growing in the soil. The fungus is found in the United States, in areas east of the Great Plains. Coprinus ebulbosus and Coprinus quadrifidus are names assigned by Charles Horton Peck to what he believed were species distinct from C. variegata; they were later shown to represent the same species, and are now synonyms. The mushroom is not recommended for consumption, and has been shown to cause allergic reactions in susceptible individuals.
Amanita atkinsoniana, also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. It is found in the northeastern, southeastern, and southern United States as well as southern Canada, where it grows solitarily or in small groups on the ground in mixed woods. The fruit body is white to brownish, with caps that measure up to 12.5 cm (5 in) in diameter, and stems up to 20 cm long and 2.5 cm (1 in) thick. The surface of the cap is covered with reddish-brown to grayish-brown conical warts. The stem has a bulbous base covered with grayish-brown scales. The fruit bodies smell faintly like bleaching powder. Although not known to be poisonous, the mushroom is not recommended for consumption.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The fruit bodies are medium to large, with caps up to 17 cm (6.7 in) wide, and a stem up to 25 cm (9.8 in) long and 3 cm (1.2 in) thick. The warts on the whitish cap surface are large—up to 6 mm (0.24 in) wide and 4 mm (0.16 in) high. The stem has a large bulb at its base, covered with whitish to brownish scales, that may root several centimeters into the soil. The ring on the stem is thick and cotton- or felt-like. It is widely distributed in mixed and deciduous forests of the southeastern United States, where it grows solitarily or in groups on the ground in late summer and autumn. The mushrooms have a unique odor resembling bleaching powder.
Volvariella bombycina, commonly known as the silky volvariella, silky sheath, silky rosegill, silver-silk straw mushroom, or tree mushroom, is a species of edible mushroom in the family Pluteaceae. It is an uncommon but widespread species, having been reported from Asia, Australia, the Caribbean, Europe, and North America. The fruit body (mushroom) begins developing in a thin, egg-like sac. This ruptures and the stem expands quickly, leaving the sac at the base of the stem as a volva. The cap, which can attain a diameter of up to 20 centimetres, is white to slightly yellowish and covered with silky hairs. On the underside of the cap are closely spaced gills, free from attachment to the stem, and initially white before turning pink as the spores mature. The mushroom grows singly or in clusters, often appearing in old knotholes and wounds in elms and maples. V. bombycina contains compounds with antibacterial properties.
Tricholoma vaccinum, commonly known as the russet scaly tricholoma, the scaly knight, or the fuzztop, is a fungus of the agaric genus Tricholoma. It produces medium-sized fruit bodies (mushrooms) that have a distinctive hairy reddish-brown cap with a shaggy margin when young. The cap, which can reach a diameter of up to 6.5 cm (2.6 in) wide, breaks up into flattened scales in maturity. It has cream-buff to pinkish gills with brown spots. Its fibrous, hollow stipe is white above and reddish brown below, and measures 4 to 7.5 cm long. Although young fruit bodies have a partial veil, it does not leave a ring on the stipe.
Pholiota squarrosoides is a species of mushroom in the family Strophariaceae. It is similar to the species Pholiota squarrosa. There are differing accounts on whether the mushroom is edible.
