Hydnum repandum, commonly known as the sweet tooth, wood hedgehog or hedgehog mushroom, is a basidiomycete fungus of the family Hydnaceae. First described by Carl Linnaeus in 1753, it is the type species of the genus Hydnum. The fungus produces fruit bodies (mushrooms) that are characterized by their spore-bearing structures—in the form of spines rather than gills—which hang down from the underside of the cap. The cap is dry, colored yellow to light orange to brown, and often develops an irregular shape, especially when it has grown closely crowded with adjacent fruit bodies. The mushroom tissue is white with a pleasant odor and a spicy or bitter taste. All parts of the mushroom stain orange with age or when bruised.
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.
Phellodon is a genus of tooth fungi in the family Bankeraceae. Species have small- to medium-sized fruitbodies with white spines on the underside from which spores are released. All Phellodon have a short stalk or stipe, and so the genus falls into the group known as stipitate hydnoid fungi. The tough and leathery flesh usually has a pleasant, fragrant odor, and develops a cork-like texture when dry. Neighboring fruitbodies can fuse, sometimes producing large mats of joined caps. Phellodon species produce a white spore print, while the individual spores are roughly spherical to ellipsoid in shape, with spiny surfaces.
Sarcodon is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales, known for its almost universal ectomycorrhizal ecology. The genus owes its name to the presence of teeth-like spines on the hymenophore, from ancient Greek; sarco = flesh and odon = tooth. For this reason they are commonly called "tooth fungi", or "Hydnoid fungi".
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.
Hericium abietis, commonly known as the bear's head or the western coral hedgehog, is an edible mushroom in the tooth fungus group. It grows on conifer stumps or logs in North America, producing a cream white fruit body up to 10–75 cm (4–30 in) tall and wide. It fruits from after the start of the fall rains to mid-season.
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.
Auriscalpium vulgare, commonly known as the pinecone mushroom, the cone tooth, or the ear-pick fungus, is a species of fungus in the family Auriscalpiaceae of the order Russulales. It was first described in 1753 by Carl Linnaeus, who included it as a member of the tooth fungi genus Hydnum, but British mycologist Samuel Frederick Gray recognized its uniqueness and in 1821 transferred it to the genus Auriscalpium that he created to contain it. The fungus is widely distributed in Europe, Central America, North America, and temperate Asia. Although common, its small size and nondescript colors lead it to be easily overlooked in the pine woods where it grows. A. vulgare is not generally considered edible because of its tough texture, but some historical literature says it used to be consumed in France and Italy.
Phellodon tomentosus, commonly known as the zoned cork hydnum, is a species of tooth fungus in the family Bankeraceae. First described as Hydnum tomentosum by Carl Linnaeus in 1753, it was transferred to the genus Phellodon by Howard James Banker in 1906. It is found in Asia, Europe, and North America.
Hydnellum fuscoindicum is a species of tooth fungus in the genus Hydnellum. It is found in the Pacific Northwest in moss around western hemlocks. It produces fruit bodies with a violet-black cap, violet flesh, and violet spines on the cap underside. The odor and taste are very farinaceous. The fungus was first described by Kenneth A. Harrison in 1964 as a species of Hydnum, then transferred to Sarcodon in 1967 by Rudolph Arnold Maas Geesteranus. He placed this species in section Violacei of Sarcodon, along with H. fuligineoviolaceum and H. joeides.
Hydnellum cyanopodium, commonly known as the blue foot or bleeding blue tooth, is an inedible fungus in the family Bankeraceae. It occurs in the Pacific Northwest region of North America.
Sarcodon lanuginosus is a species of tooth fungus in the family Bankeraceae. It was described as new to science in 1961 by mycologist Kenneth A. Harrison, who initially called it Hydnum lanuginosum. He transferred it to the genus Sarcodon in 1984. It is found in Nova Scotia, Canada, where it fruits on the ground singly or in groups under spruce and fir. The type collection was made in Cape Split, Kings County.
Sarcodon cyanellus is a species of tooth fungus in the family Bankeraceae. Found in the Pacific Northwest region of North America, where it associates with Pinaceae, it was described as new to science in 1964 by mycologist Kenneth A. Harrison, who initially called it Hydnum cyanellum. He transferred it to the genus Sarcodon in 1984. It has a vinaceous-violet to bluish-black cap.
Sarcodon calvatus 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 calvatum. He transferred it to the genus Sarcodon in 1984. It is found in North America.
Hydnellum martioflavum is a species of tooth fungus in the family Bankeraceae, found in Europe and North America.
Sarcodon thwaitesii is a species of tooth fungus in the family Bankeraceae. It is found in Asia, Europe, and New Zealand, where it fruits on the ground in mixed forest.
Sarcodon scabripes is a species of fungus in the family Bankeraceae found in Asia, Europe, and North America. It was originally described in 1897 as Hydnum scabripes by Charles Horton Peck. Howard James Banker transferred it to the genus Sarcodon in 1906. The fungus makes fruit bodies with a drab gray to flesh-colored cap, and flesh that is white. In addition to the United States, where it was first documented, S. scabripes has been reported from Japan and the Sverdlovsk Oblast region of Russia.
Sarcodon subfelleus is a species of tooth fungus in the family Bankeraceae. It was described as new to science in 1961 by mycologist Kenneth A. Harrison, who initially called it Hydnum subfelleum. He transferred it to the genus Sarcodon in 1984. It is found in Nova Scotia, Canada, where it fruits on the ground singly or in groups under spruce and fir. The type collection was made in Glenmont, Kings County.
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.
