Mycena semivestipes is a species of agaric fungus in the family Mycenaceae. It is found in eastern North America.
First described in 1895 as Omphalina semivestipes by Charles Horton Peck, [3] the species was transferred to Mycena in 1947 by Alexander H. Smith. The type collection was made in Newfoundland, Canada. [2]
The cap is initially convex to somewhat conical before flattening out in age; it attains a diameter of 0.8–3.5 cm (0.3–1.4 in) wide. The cap surface, smooth and slightly lubricous, is deep viscous to dark brown in the center. The margin is somewhat translucent, so that the grooves made by the gills are discernible. The thin flesh has a firm texture similar to cartilage, a distinct strong nitrous odor, and a mild to somewhat bitter taste. The gills have an adnate attachment, but often recede from the stipe as the mushroom matures. Their color is white to dirty pink. [4] They can develop reddish-brown spots in age. [5] Interspersed between the gills are two or three tiers of lamellae (short gills). The stipe measures 1.6–6 cm (0.6–2.4 in) long by 1–3 mm (0.04–0.12 in) thick, and is roughly the same thickness throughout its length. Its surface texture is smooth or lightly pruinose (as if dusted with a fine white powder), and it is dark brown at the base and whitish at the top. [4] There can be fine hairs at the base, particularly in young specimens. [5]
The spore print is white. Spores are thin walled, ellipsoid, hyaline (translucent), and measure 5–7 by 3–3.4 μm. They are amyloid. The basidia are four-spored, club shaped, and measure 21–30 by 4.5–5.4 μm. Cheilocystidia (cystidia on the gill edge) are club-shaped, hyaline to dark grey, and measure 24–34 by 5–11 μm. [4]
Mycena semivestipes is a saprobic species that obtains nutrients from the decomposing logs and stumps of hardwoods, [5] in which it fruits in dense clusters. Fruiting occurs in later fall and winter in eastern North America. [4]
Neolentinus ponderosus, commonly known as the giant sawgill, or ponderous lentinus, is a species of fungus in the family Gloeophyllaceae. Found in western North America, it was originally described in 1965 as a species of Lentinus by American mycologist Orson K. Miller.
Mycena haematopus, commonly known as the bleeding fairy helmet, the burgundydrop bonnet, or the bleeding Mycena, is a species of fungus in the family Mycenaceae, of the order Agaricales. It is widespread and common in Europe and North America, and has also been collected in Japan and Venezuela. It is saprotrophic—meaning that it obtains nutrients by consuming decomposing organic matter—and the fruit bodies appear in small groups or clusters on the decaying logs, trunks, and stumps of deciduous trees, particularly beech. The fungus, first described scientifically in 1799, is classified in the section Lactipedes of the genus Mycena, along with other species that produce a milky or colored latex.
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.
Mycena cinerella, commonly known as the mealy bonnet, is an inedible species of mushroom in the family Mycenaceae. It is found in Europe and the United States, where it grows in groups on fallen leaves and needles under pine and Douglas fir. The small grayish mushrooms have caps that are up to 1.5 cm (0.6 in) wide atop stipes that are 5 cm (2.0 in) long and 2.5 mm (0.10 in) thick. Its gills are grayish-white and adnate, with a "tooth" that runs slightly down the stipe. The fungus has both two- and four-spored basidia. As its common name suggests, it smells mealy.
Gymnopilus punctifolius is a species of mushroom in the family Hymenogastraceae found in North America.
Leucopholiota decorosa is a species of fungus in the mushroom family Tricholomataceae. Commonly known as the decorated pholiota, it is distinguished by its fruit body which is covered with pointed brown, curved scales on the cap and stem, and by its white gills. Found in the eastern United States, France, and Pakistan, it is saprobic, growing on the decaying wood of hardwood trees. L. decorosa was first described by American mycologist Charles Horton Peck as Agaricus decorosus in 1873, and the species has been transferred to several genera in its history, including Tricholoma, Tricholomopsis, Armillaria, and Floccularia. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus Leucopholiota in a 1996 publication. Lookalike species with similar colors and scaly fruit bodies include Pholiota squarrosoides, Phaeomarasmius erinaceellus, and Leucopholiota lignicola. L. decorosa is considered an edible mushroom.
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.
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.
Mycena californiensis is a species of fungus in the family Mycenaceae. It is a common and abundant species in the coastal oak woodlands of California, where it grows saprobically, feeding on the fallen leaves and acorns of various oak species. First described in 1860 by Berkeley and Curtis, the species was collected four years earlier during an exploring and surveying expedition. It was subsequently considered a doubtful species by later Mycena researchers, until a 1999 publication validated the taxon. Mycena elegantula is considered a synonym.
Lactarius affinis, commonly known as the kindred milk cap, is a species of milk-cap mushroom in the family Russulaceae. It is found northeastern North America, where it fruits in the summer and fall, and is common in the Great Lakes region. Its fruit bodies have medium to large, slimy dull yellow or brownish caps. Although not considered poisonous, it is unpalatable because of its highly acrid taste.
Lactifluus deceptivus, commonly known as the deceiving milkcap, is a common species of fungus in the family Russulaceae. It is found throughout eastern North America on the ground in coniferous forests near hemlock or deciduous forests near oak, and in oak-dominated forests of Costa Rica. It produces large mushrooms with funnel-shaped caps reaching up to 25 cm (9.8 in) in diameter, on top of hard white stems that may reach 4–10 cm (1.6–3.9 in) long and up to 3 cm (1.2 in) thick. The gills are closely spaced together and yellowish-cream in color. When young, the cap is white in all parts, but the depressed center becomes dull brownish in age and breaks up into scales. The edge of the cap has a roll of cottony tissue that collapses as the cap expands. The surface of the stem—especially near the base—has a velvety texture. The mushroom "bleeds" a milky white acrid latex when it is cut or injured. Similar milk-cap species with which L. deceptivus might be confused include Lactifluus piperatus, L. pseudodeceptivus, L. caeruleitinctus, L. subvellereus, Lactarius arcuatus and Lactarius parvulus.
Mycena maculata, commonly known as the reddish-spotted Mycena, is a species of fungus in the family Mycenaceae. The fruit bodies, or mushrooms, have conic to bell-shaped to convex caps that are initially dark brown but fade to brownish-gray when young, reaching diameters of up to 4 cm. They are typically wrinkled or somewhat grooved, and have reddish-brown spots in age, or after being cut or bruised. The whitish to pale gray gills also become spotted reddish-brown as they mature. The stem, up to 8 cm (3 in) long and covered with whitish hairs at its base, can also develop reddish stains. The mycelium of M. maculata has bioluminescent properties. The saprobic fungus is found in Europe and North America, where it grows in groups or clusters on the rotting wood of both hardwoods and conifers. The edibility of the fungus is unknown. Although the species is known for, and named after its propensity to stain reddish, occasionally these stains do not appear, making it virtually indistinguishable from M. galericulata.
Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. First formally described in 1803, it was given its current name in 1872. Widely distributed, it is common in Europe and North America, and has also been collected in North Africa, Central America, and Japan. The fungus is saprobic, and produces fruit bodies (mushrooms) that grow on the floor of coniferous forests. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges. A microscopic characteristic is the club-shaped cystidia that are covered with numerous spiky projections, resembling a mace. The edibility of the mushroom has not been determined. M. aurantiomarginata can be distinguished from similar Mycena species by differences in size, color, and substrate. A 2010 publication reported the discovery and characterization of a novel pigment named mycenaaurin A, isolated from the mushroom. The pigment is responsible for its color, and it has antibiotic activity that may function to prevent certain bacteria from growing on the mushroom.
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.
Mycena atkinsoniana is a species of agaric fungus in the family Mycenaceae. It is one of the so-called "bleeding mycenas" that will ooze yellow to orange juice when injured. Other distinguishing features include the upper stem surface that is decorated with tiny purplish-brown fibers, and the gills, which are pale yellow with maroon edges. The reddish-brown caps are smooth with a grooved margin, and up to 3 cm (1.2 in) wide. Mycena atkinsoniana is known from the United States and Canada, where it grows scattered or in groups on leaf litter in forests during the summer and autumn. It was originally described from collections associated with beech, but it is also frequently found under eastern North American oaks.
Tricholoma pullum is a mushroom of the agaric genus Tricholoma. Described as new to science in 1989, it is found in eastern North America.
Mycena purpureofusca, commonly known as the purple edge bonnet, is a species of agaric fungus in the family Mycenaceae. First described by Charles Horton Peck in 1885, the species is found in Europe and North America, where it grows on the decaying wood and debris of conifers, including cones. Fruit bodies have conical to bell-shaped purple caps up to 2.5 cm (1 in) set atop slender stipes up to 10 cm (4 in) long. The mushroom is named for the characteristic dark greyish-purple color of its gill edges. In the field, M. purpureofusca mushrooms can usually be distinguished from similar species by characteristics such as the dark purple gill edges, the deep purple cap center, and its cartilagineous consistency. The fungus contains a laccase enzyme that has been investigated scientifically for its potential to detoxify recalcitrant industrial dyes used in textile dyeing and printing processes.
Russula crustosa, commonly known as the crusty russula, is a species of fungus in the family Russulaceae. It is found in Asia and North America.
Marasmius fulvoferrugineus is a species of agaric fungus in the family Marasmiaceae. Described as new to science in 1976, it is found in the southeastern United States. The mushroom is frequently confused with Marasmius siccus, and microscopy is needed to reliably distinguish between them.
Hygrocybe appalachianensis, commonly known as the Appalachian waxy cap, is a gilled fungus of the waxcap family. It is found in the eastern United States, where it fruits singly, in groups, or clusters on the ground in deciduous and mixed forests. The species, described in 1963 from collections made in the Appalachian Mountains, was originally classified in the related genus Hygrophorus. It was transferred to Hygrocybe in 1998, in which it has been proposed as the type species of section Pseudofirmae.
