Hydnellum joeides (the epithet is sometimes spelled ionides or jonides) [3] is a species of tooth fungus in the family Bankeraceae .
It was first described by Italian botanist Giovanni Passerini in 1872 as Hydnum joeides. [4] Frédéric Bataille transferred it to the genus Sarcodon in 1924. [5]
The fungus makes fruit bodies with flattened to concave caps measuring 2.5–10 cm (1.0–3.9 in) in diameter. They initially have a velvety surface texture that later breaks up into reddish-brown scales. The crowded spines on the cap underside are up to 3 mm long, and are decurrent on the stipe. Initially pale pink, they become brownish in age. Spores are tuberculate (covered in warts), and measure 6.3–7.2 by 4–4.7 µm. [6]
It is reportedly inedible. [7]
The fungus is found in western and central Europe, where it is an ectomycorrhizal symbiont of European beech (Fagus sylvatica), English oak (Quercus robur), and probably sessile oak (Quercus petraea). It is on the red lists of several countries: Flandres, France and Norway (critically endangered); The Netherlands, Germany, Lower Saxony and Switzerland (endangered); and Sweden (vulnerable). Because of the continued decline in sightings in Europe, it has been proposed for inclusion on the IUCN Red List of Threatened Species. [8]
The species has also been reported from the United States, [9] and New Zealand, although mycologist Eef Arnolds regards these records as doubtful because of discrepancies in the reported sizes of the spores. [8]
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.
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 life style. The genus owes its name to the presence of teeth-like spines on the hymenophore, it is derived from ancient Greek; sarco = flesh and odon = tooth. This is why 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.
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus Hydnum, but it is now known that not all hydnoid species are closely related.
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.
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 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 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.
Hydnellum underwoodii is an inedible species of tooth fungus in the family Bankeraceae. Found in North America, it was described as new to science in 1906 by American mycologist Howard James Banker. Its reddish-brown, convex to flattened cap measures 5–14 cm (2.0–5.5 in) in diameter. Reddish-brown, partially erect scales adorn the cap surface. Spines on the cap underside are 1–3 mm long; they are initially white, becoming brown with grayish tips in age. The oval to spherical spores are 6–7.5 by 5.5–6.5 µm. The fungus fruits singly or scattered, on the ground in coniferous forests.
Hydnellum lundellii is a species of tooth fungus in the family Bankeraceae. Found in Europe, it was described as new to science in 1969 by mycologists Rudolph Arnold Maas Geesteranus and John Axel Nannfeldt.
Hydnellum fuligineoviolaceum is a species of tooth fungus in the family Bankeraceae. It was originally described in 1874 by Hungarian mycologist Károly Kalchbrenner as Hydnum fuligineoviolaceum, in Elias Fries's work Hymenomycetes europaei. Narcisse Théophile Patouillard transferred it to the genus Sarcodon in 1900. Sarcodon talpa, published by Rudolph Arnold Maas Geesteranus in 1967, is a synonym.
Hydnellum amygdaliolens is a species of tooth fungus in the family Bankeraceae. Found in the Iberian Peninsula, it was described as new to science in 2011. It smells strongly of bitter almonds. Its spores measure 5.25–6.5 by 4.5 μm.
Hydnellum martioflavum is a species of tooth fungus in the family Bankeraceae, found in Europe and North America.
Sarcodon wrightii is a species of tooth fungus in the family Bankeraceae. It was first described in 1860 by Miles Berkeley and Moses Ashley Curtis as Hydnum wrightii. They were sent a specimen collected from Japan as part of the North Pacific Exploring and Surveying Expedition (1853–56). Rudolph Arnold Maas Geesteranus transferred it to the genus Sarcodon in 1967. The fungus produces roughly spherical spores that are tuberculate and measure 5.5–6.5 by 4.5–5.5 μm.
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.
Hydnellum fennicum is a species of tooth fungus in the family Bankeraceae. It was originally described by Petter Karsten in 1882 as a variety of Sarcodon scabrosus. Karsten promoted it to a distinct species in 1887. It is considered critically endangered in Switzerland. It is inedible.
Hydnellum versipelle is a species of tooth fungus in the family Bankeraceae. It was originally described by Elias Fries in 1861 as Hydnum versipelle. Taisiya Lvovna Nikolayeva transferred it to the genus Sarcodon in 1961. Hydnum crassum, published by Kenneth A. Harrison in 1961, is a synonym. The species is found in Europe and North America.
