Hydnellum cyanopodium, commonly known as the blue foot [2] or bleeding blue tooth, [1] is an inedible fungus in the family Bankeraceae. It occurs in the Pacific Northwest region of North America.
The fungus was described as new to science to Canadian mycologist Kenneth A. Harrison in 1964. [3] The type was collected by Alexander H. Smith in Crescent City, California, on November 1937. It is kept at University of Michigan Herbarium. [4] Harrison considered this species—in addition to H. cruentum and H. scleropodium —to be members of the stirps (species thought to be descendants of a common ancestor) he called "cruentum". This stirps is characterized by the presence of red juice drops on young fruit bodies, bluish spines, and similar spore morphology. [3]
The fruit bodies have irregularly shaped caps measuring 4–8 cm (1.6–3.1 in) in diameter. The cap surface is rough with small hard points, has ridges, and is a dark blue-wine red color that changes later to lavender. The outer cap edge turns whitish with age. Young fruit bodies are covered with drops of red juice. The flesh has a woody or cork-like texture, and a strong, "disagreeable" odor and taste. [3]
The spines on the underside of the caps are up to 3 mm long with a color ranging from initially grayish violet blue to wine-blue with brownish tints, to dull grayish-green. The stipe measures 2–5 cm (0.8–2.0 in) long by 1–2 cm (0.4–0.8 in) thick, and tends to root into the ground. Its color is deep bluish-black (with similarly colored flesh within) with a whitish mycelium at the base. Staining the spines or the cap or stipe flesh with potassium hydroxide turns it blue-green. Spores are angular, cross-shaped with four to six thick points, and measure 4–5 by 3.5–4.5 µm. The spore shape has been likened to jacks. [3]
The lookalike species Hydnellum caeruleum can be readily distinguished from H. cyanopodium by its lack of a medicinal odor, the absence of red juice drops, and the orange to rusty-brown color of its stipe. H. caeruleum can be further distinguished microscopically by its roughly spherical spores. [2] H. scleropodium has a smoother texture and more pallid colors. H. cruentum , found in Nova Scotia, Canada, has an odor that has been described as "medicinal". [3]
Hydnellum cyanopodium fruits singly, in groups, or with fruit bodies fused together. It occurs under Sitka spruce ( Picea sitchensis ) and pine (Pinus spp.) in California. [3] The fungus is also found in Oregon. [5]
Hydnellum peckii is a fungus in the genus Hydnellum of the family Bankeraceae. It is a hydnoid species, producing spores on the surface of vertical spines or tooth-like projections that hang from the undersurface of the fruit bodies. It is found in North America, Europe, and was recently discovered in Iran (2008) and Korea (2010). Hydnellum peckii is a mycorrhizal species, and forms mutually beneficial relationships with a variety of coniferous trees, growing on the ground singly, scattered, or in fused masses.
Hydnellum is a genus of tooth fungi in the family Bankeraceae. Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of Hydnellum fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance.
Hydnellum caeruleum is an inedible fungus found in North America, Europe, and temperate areas of Asia. Its common names include blue-green hydnellum, blue spine, blue tooth, and bluish tooth.
Hydnellum aurantiacum is an inedible fungus, commonly known as the orange spine or orange Hydnellum for its reddish orange or rusty red colored fruit bodies. Like other tooth fungi, it bears a layer of spines rather than gills on the underside of the cap. Due to substantial declines in sightings, this species is listed as critically endangered in the United Kingdom.
Mycena sanguinolenta, commonly known as the bleeding bonnet, the smaller bleeding Mycena, or the terrestrial bleeding Mycena, is a species of mushroom in the family Mycenaceae. It is a common and widely distributed species, and has been found in North America, Europe, Australia, and Asia. The fungus produces reddish-brown to reddish-purple fruit bodies with conic to bell-shaped caps up to 1.5 cm (0.6 in) wide held by slender stipes up to 6 cm (2.4 in) high. When fresh, the fruit bodies will "bleed" a dark reddish-purple sap. The similar Mycena haematopus is larger, and grows on decaying wood, usually in clumps. M. sanguinolenta contains alkaloid pigments that are unique to the species, may produce an antifungal compound, and is bioluminescent. The edibility of the mushroom has not been determined.
Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.
Hydnellum ferrugineum, commonly known as the mealy tooth or the reddish-brown corky spine fungus, is a species of tooth fungus in the family Bankeraceae. A widely distributed species, it is found in north Africa, Asia, Europe, and North America. The fungus fruits on the ground singly or in clusters in conifer forest, usually in poor or sandy soil. Fruit bodies are somewhat top-shaped, measuring 3–10 cm (1–4 in) in diameter. Their velvety surfaces, initially white to pink, sometimes exude drops of red liquid. The lower surface of the fruit body features white to reddish-brown spines up to 6 mm long. Mature fruit bodies become dark reddish brown in color, and are then difficult to distinguish from other similar Hydnellum species. H. ferrugineum forms a mat of mycelia in the humus and upper soil where it grows. The presence of the fungus changes the characteristics of the soil, making it more podzolized.
Mycena fonticola is a species of fungus in the family Mycenaceae. First reported in 2007, it is known only from central Honshu, in Japan, where it grows on dead leaves and twigs in low-elevation forests dominated by oak trees. The fruit body of the fungus has a smooth, violet-brown cap up to 2.5 cm (1.0 in) in diameter, and a slender stem up to 10 cm (3.9 in) long. Distinguishing microscopic characteristics of the mushroom include the relatively large, distinctly amyloid spores, the smooth, spindle-shaped cheilocystidia, the absence of pleurocystidia, the diverticulate hyphae of the cap cuticle, and the absence of clamp connections.
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.
Tricholoma vernaticum is an agaric fungus of the genus Tricholoma native to the Pacific Northwest region of the United States. The fungus was originally described in 1976 as a species of Armillaria when that genus was more inclusive; it received its current name twenty years later. The stout fruit bodies (mushrooms) have moist white to grayish caps, a membranous ring on the stipe, and an odor resembling cucumbers. Mycorrhizal with conifers, the fungus fruits in the spring or early summer, with its mushrooms appearing on the ground singly or in groups at high elevations, often at the edge of melting snowbanks. The edibility of the mushroom is unknown, but it has a strong unpleasant odor and a mealy taste.
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.
Hygrophorus caeruleus is a rare species of agaric fungus in the family Hygrophoraceae. Found in the western United States, the mushroom is characterized by its stout fruit body including blue-tinted cap margin and stipe, blue-grey to bluish green gills, and odor of rancid meal.
Hydnellum auratile is a tooth fungus in the family Bankeraceae. Fruit bodies of the fungus consist of closely grouped, funnel-shaped caps up to 5 cm (2.0 in) in diameter. The caps are initially bright orange with a white rim, and have a felt-like surface. On the cap underside, the hymenium has hanging orange spines with whitish tips. These spines extend a ways down the length of the short stipe. The flesh is orange in both the cap and stipe. In mass, the spores are brown. Microscopically, they measure 4–5 by 3.5–4.5 µm and have short, rounded tubercles on the surface. The widespread Hydnellum aurantiacum is a close lookalike, but can be distinguished by having a white to buff cap, dull orange to brown flesh, and white spines.
Hydnellum compactum is a tooth fungus in the family Bankeraceae. It is found in Europe, where it grows in deciduous forest, typically under beech. Fruit bodies of the fungus grow singly or in groups. They are top-shaped, with convex or flattened upper surfaces up to 10 cm (4 in) in diameter. The surface texture is initially felt-like before becoming pitted and rough in age. The stipe, roughly the same color as the cap, is solid and measures 2–4 cm (0.8–1.6 in) long by 1–3 cm (0.4–1.2 in) thick. On the fertile cap underside are white to purple-brown, curved spines up to 5 mm long. The color is whitish at first but gradually turns dark brown to blackish. Its spores measure 5.5–6 by 3.5–4.5 µm, and feature tubercles that sometimes have a sunken tip. It is considered endangered in Switzerland.
Hydnellum scleropodium is a rare species of tooth fungus in the family Bankeraceae. It was described as new to science in 1964 by Canadian mycologist Kenneth A. Harrison. The fungus has been collected in Tennessee, North Carolina, and Nova Scotia, in both mixed and coniferous forest. Its fruitbody has an irregular, brownish cap measuring 10–25 cm (4–10 in) wide. The sclerotium-like stipe measures 3–9 cm (1.2–3.5 in) long by 2–4 cm (0.8–1.6 in) thick, and roots into the ground. The flesh has a strong, fragrant odor. Spines on the cap underside, blue in color, are up to 11 mm long.
Hydnellum cruentum is a tooth fungus in the family Bankeraceae. Found in Nova Scotia, Canada, it was described as new to science in 1961 by mycologist Kenneth A. Harrison. Fruitbodies grow singly, in groups, or as fused masses under spruce. Individual caps measure 3–10 cm (1.2–3.9 in) in diameter, and have a club- or cushion-like shape. They are initially light brown, but darken somewhat in maturity. Young fruitbodies can exude droplets of red juice. Spines on the cap underside are lilac to dark blue, and up to 4 mm long. The angular spores are angular, with 4 to 6 unusually prominent outgrowths, and measure 4–4.5 by 3.5–4.5 µm. Harrison described the spores as "so irregular that some resemble stout metal jackstones." The flesh is pale gray to pale brown, and has a strong "medicinal" odor.
Hydnellum scrobiculatum, commonly known as the ridged tooth, is a tooth fungus in the family Bankeraceae. Widely distributed in the Northern Hemisphere, it is found in Asia, Europe, and North America.
Phellodon niger, commonly known as the black tooth, is a species of tooth fungus in the family Bankeraceae, and the type species of the genus Phellodon. It was originally described by Elias Magnus Fries in 1815 as a species of Hydnum. Petter Karsten included it as one of the original three species when he circumscribed Phellodon in 1881. The fungus is found in Europe and North America, although molecular studies suggest that the North American populations represent a similar but genetically distinct species.
Sarcodon rimosus, commonly known as the cracked hydnum, is a species of tooth fungus in the family Bankeraceae. Found in the Pacific Northwest region of North America, it was described as new to science in 1964 by mycologist Kenneth A. Harrison, who initially called it Hydnum rimosum. He transferred it to the genus Sarcodon in 1984. Fruit bodies of S. rimosum have convex to somewhat depressed caps that are 4–12 cm (1.6–4.7 in) in diameter. The surface becomes scaly in age, often developing conspicuous cracks and fissures. It is brown with violet tints. The flesh lacks any significant taste and odor. Underneath the cap cuticle, the flesh turns a bluish-green color when tested with a solution of potassium hydroxide. The brownish-pinks spines on the cap underside are typically 2.5–7 mm long, extending decurrently on the stipe. Spores are roughly spherical with fine warts on the surface, and measure 5–6.5 by 4.5–5 µm. The hyphae do not have clamp connections.
Sarcodon ustalis is a species of tooth fungus in the family Bankeraceae. It was described as new to science in 1964 by mycologist Kenneth A. Harrison, who initially called it Hydnum ustalie. He transferred it to the genus Sarcodon in 1984. It is found in Michigan, where it fruits on the ground in groups under Jack Pine. The type was collected by Ingrid Bartelli in Marquette, Michigan.
