Naematoloma P.Karst. (1880)

Hypholoma is a genus of fungi which are quite well known due to the commonness of sulphur tuft (Hypholoma fasciculare) on stumps in temperate woodlands. Species in this genus are easily recognizable because the dark spores create a distinctive greenish effect on the yellow cap underside. Hypholoma means "mushrooms with threads" because of the thread-like veil that connects the cap to the stem when young and for the bundles of rhizomorphs which radiate outwards from the stem base. [2] Other well-known species are H. capnoides and H. lateritium .

Synonyms

Sometimes Hypholoma has not been considered a genus in its own right, but it has been grouped together with Stropharia and Psilocybe under the name of Geophila, Naematoloma, or Nematoloma.

<i>Hypholoma capnoides</i>

Hypholoma capnoides is an edible mushroom in the family Strophariaceae. Like its poisonous or suspect relatives H. fasciculare and H. lateritium, H. capnoides grows on decaying wood, for example in tufts on old tree stumps.

<i>Hypholoma fasciculare</i>

Hypholoma fasciculare, commonly known as the sulphur tuft or clustered woodlover, is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This saprophagic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.

<i>Hypholoma lateritium</i>

Hypholoma lateritium, sometimes called brick cap, chestnut mushroom, cinnamon cap, brick top, red woodlover, or kuritake is rarer and less well-known than its relatives, the inedible, and poisonous sulfur tuft and the edible Hypholoma capnoides. Its fruiting bodies are generally larger than either of these. Hypholoma sublateritium is a synonym.

<i>Gymnopilus sapineus</i> Species of fungus

Gymnopilus sapineus, commonly known as scaly rustgill, is a small and widely distributed mushroom which grows in dense clusters on dead conifer wood. It has a rusty orange spore print and a bitter taste. This species does not stain blue and lacks the hallucinogen psilocybin.

<i>Hebeloma radicosum</i> Species of fungus

Hebeloma radicosum, commonly known as the rooting poison pie, is a species of agaric fungus in the family Hymenogastraceae. Fruit bodies (mushrooms) can be identified by the tapering root-like stipe base, as well as the almond-like odor. Found in Japan, Europe, and North America, it is an ammonia fungus, and fruits on mole, mouse, or shrew middens.

<i>Agaricus arorae</i> Species of fungus

Agaricus arorae is a moderate-sized, forest-dwelling mushroom that exhibits distinctive color changes. It fruits early in the mushroom season. Unusually within the genus Agaricus, the mushroom's cap cuticle turns yellow when exposed to a base such as potassium hydroxide or sodium hydroxide but stains red when cut. In the field, it has a brownish, fibrillose/squamulose cap, which turns red when bruised. Agaricus arorae was first described from Santa Cruz County but since has been found in San Mateo and Alameda counties. Agaricus arorae can be distinguished by its scales and a conspicuous stipe.

Psilocybe makarorae is a species of psilocybin mushroom in the family Strophariaceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.

<i>Amanita nothofagi</i> Species of fungus

Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.

<i>Lepiota clypeolaria</i>

Lepiota clypeolaria, commonly known as the shield dapperling or the shaggy-stalked Lepiota, is a common, poisonous mushroom in the genus Lepiota. It is widely distributed in northern temperate zones, where it grows in deciduous and coniferous forest. Fruit bodies have a brownish cap, a shaggy stipe with a collapsed, sheathing ring or ring zone, and spindle-shaped spores.

<i>Amanita atkinsoniana</i> Species of fungus

Amanita atkinsoniana 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.

<i>Psilocybe pelliculosa</i> Species of fungus

Psilocybe pelliculosa is a species of fungus in the family Hymenogastraceae. The fruit bodies, or mushrooms, have a conical brownish cap up to 2 cm (0.8 in) in diameter atop a slender stem up to 8 cm (3.1 in) long. It has a white partial veil that does not leave a ring on the stem. American mycologist Alexander H. Smith first described the species in 1937 as a member of the genus known today as Psathyrella; it was transferred to Psilocybe by Rolf Singer in 1958.

<i>Amanita crocea</i>

Amanita crocea, the saffron ringless amanita, is a species of Amanita widely distributed in Europe.

<i>Gymnopilus maritimus</i> Species of fungus in the family Cortinariaceae first collected in northern Sardinia

Gymnopilus maritimus is a fungus species of the family Cortinariaceae first collected in northern Sardinia, Italy, in 2006. The species produces moderately sized, sturdy mushrooms of a reddish-orange colour. The cap, which can measure up to 70 millimetres (3 in) across, is covered in orange fibrils, and sometimes has small scales. The yellowish stem measures up to 110 mm (4 in) in length by 8 mm (0.3 in) in width, and sometimes shows remnants of the partial veil. The mushrooms have thick gills of a variable colour, ranging from yellow to rust but staining darker, and the yellow flesh has a mild taste. The mushrooms leave a rusty-brown spore print, while the spores themselves measure from 7.5–11.5 micrometres (0.00030–0.00045 in) in length. The species is most similar in appearance to G. arenophilus and G. fulgens, but can be differentiated from both morphologically. Despite the similarities, it is not closely related to either, suggesting convergent evolution. Instead, within the genus Gymnopilus, it is most closely related to the spectabilis–imperialis clade. However, it is not particularly similar to any of its closest relatives.

<i>Xeromphalina setulipes</i> Species of fungus

Xeromphalina setulipes is a species of fungus of the family Mycenaceae. First collected in 2005, it was described and named in 2010 by Fernando Esteve-Raventós and Gabriel Moreno, and is known only from oak forests in Ciudad Real Province, Spain. The species produces mushrooms with dark reddish-brown caps up to 15 millimetres (0.59 in) across, dark purplish-brown stems up to 45 millimetres (1.8 in) in height and distinctive, arched, brown gills. The mushrooms were found growing directly from the acidic soil of the forest floor, surrounded by plant waste, during November.

<i>Cortinarius vanduzerensis</i> Species of fungus

Cortinarius vanduzerensis is a species of mushroom in the family Cortinariaceae. Described as new to science in 1972, it is known only from the Pacific Northwest region of North America, where it grows under conifers such as spruce, hemlock, and Douglas-fir. The fruit bodies of the fungus, or mushrooms, have a slimy dark chestnut-brown cap that becomes deeply radially grooved or corrugated in maturity, and reaches diameters of up to 8 cm (3.1 in). The gills on the underside of the cap are initially pinkish-buff before becoming pale brown when the spores mature. The stem is lavender, measuring 10–18 cm (3.9–7.1 in) long and 1–2 cm (0.4–0.8 in) thick. The mushroom produces a rusty-brown spore print, with individual spores measuring 12–14 by 7–8 micrometers. The edibility of the mushroom has not been determined, and it has been described as "much too slippery to be of value".

Cortinarius badiolaevis is a fungus in the family Cortinariaceae. The species produces mushrooms with smooth, red-brown caps up to 5 centimetres (2.0 in) in diameter, after which it is named. It has a white stem, and yellow-brown gills. It was first described in 2011, based on specimens collected in the 1990s and 2000s. C. badiolaevis is part of the subgenus Telamonia, but is not part of any known section, and does not have any close relatives within the genus. The rare species is known from Sweden and Spain, where it grows from soil in coniferous woodland.

<i>Inocybe saliceticola</i> Species of fungus in the family Inocybaceae found in the Nordic countries

Inocybe saliceticola is a fungus found in moist habitats in the Nordic countries. The species produces brown mushrooms with caps of varying shapes up to 40 millimetres (1.6 in) across, and tall, thin stems up to 62 millimetres (2.4 in) long. At the base of the stem is a large and well-defined "bulb". The species produces unusually shaped, irregular spores, each with a few thick protrusions. This feature helps differentiate it from other species that would otherwise be similar in appearance and habit.

<i>Tricholoma vernaticum</i> Species of fungus

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.

<i>Stropharia caerulea</i>

Stropharia caerulea, commonly known as the blue roundhead, is an inedible species of agaric fungus in the family Strophariaceae. It is a common species found in Europe and North America, where it grows as a saprophyte in meadows, roadsides, hedgerows, gardens, and woodchip mulch. S. caerulea was officially described to science in 1979, although it was known to be a distinct species for about two centuries before that. The taxon Stropharia cyanea, as defined by Risto Tuomikoski in 1953, and used by several later authors, is a synonym of S. caerulea.

<i>Gymnopus fusipes</i>

Gymnopus fusipes is a parasitic species of gilled mushroom which is quite common in Europe and often grows in large clumps. It is variable but easy to recognize because the stipe soon becomes distinctively tough, bloated and ridged.
