Rhodocollybia butyracea, commonly known as the buttery collybia, [2] [3] is a species of fungus in the mushroom family Omphalotaceae. It has a number of subspecies. [4]

Contents

Description

The cap of this mushroom is 2 to 10 cm across. It is convex and becomes broadly convex or almost flat. When fresh, this species is smooth and moist. It has a reddish-brown colour fading to cinnamon. [5]

The gills are either free from the stem, or narrowly attached. They range from close to crowded and are whitish. [4] Occasionally, they develop a pinkish tone as they age, and often form fine, jagged edges.

The stem is up to 10 cm long and 1 cm thick. It is normally somewhat club-shaped. [4] It can either be moist or dry.

The flesh of this species is white. There is no distinctive odor or taste.

The spores are pale yellowish, pale pinkish, or white. [5]

Ecology

This species is saprobic. It decomposes litter from conifers, usually that of the genus Pinus, [5] and occasionally hardwoods. [6]

Habitat

Rhodocollybia butyracea is quite widely distributed in North America. [5]

Edibility

This mushroom is edible, but unsubstantial. [7]

<i>Rhodocollybia</i> Genus of fungi

Rhodocollybia is a genus of Basidiomycete mushroom. Species in this genus, formerly classified as a subgenus in Collybia, have fairly large caps, and have a pinkish-tinted spore print. Microscopically, they are characterized by having spores and basidia that are dextrinoid—staining deep reddish to reddish-brown with Melzer's reagent when tested for amyloidity. Rhodocollybia species are commonly found in temperate North America and Europe, and infrequently in Central and South America.

<i>Mycena inclinata</i> Species of fungus

Mycena inclinata, commonly known as the clustered bonnet or the oak-stump bonnet cap, is a species of mushroom in the family Mycenaceae. The doubtfully edible mushroom has a reddish-brown bell-shaped cap up to 4.5 cm (1.8 in) in diameter. The thin stem is up to 9 cm (3.5 in) tall, whitish to yellow-brown at the top but progressively becoming reddish-brown towards the base in maturity, where they are covered by a yellowish mycelium that can be up to a third of the length of the stem. The gills are pale brown to pinkish, and the spore print is white. It is a widespread saprobic fungus, and has been found in Europe, North Africa, Asia, Australasia, and North America, where it grows in small groups or tufts on fallen logs and stumps, especially of oak. British mycologist E.J.H. Corner has described two varieties of the mushroom from Borneo. Lookalike species with which M. inclinata may be confused include M. galericulata and M. maculata.

<i>Mycena pura</i> Species of fungus

Mycena pura, commonly known as the lilac mycena, lilac bonnet, is a species of mushroom in the family Mycenaceae. First called Agaricus prunus in 1794 by Christian Hendrik Persoon, it was assigned its current name in 1871 by German Paul Kummer. Mycena pura is known to bioaccumulate the element boron.

<i>Mycena overholtsii</i> Species of fungus

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.

<i>Lactarius subflammeus</i> Species of fungus

Lactarius subflammeus, commonly known as the orange milk cap, is a species of fungus in the family Russulaceae. It is found in western North America in the late summer and fall and is especially common in the Pacific Northwest, where it grows on the ground near conifers like pine and spruce. The brightly colored fruit bodies, which are slimy or sticky, have scarlet caps when young that soon fade to brilliant orange. The stem—typically longer than the width of the cap—is also bright orange but the gills are whitish. The mushroom secretes a whitish latex when it is cut or injured.

<i>Lactarius alnicola</i> Species of fungus

Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the family Russulaceae. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm (7.9 in) wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to 5 cm (2.0 in) long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. pitkinensis, known from Colorado, and var. pungens, from Michigan.

<i>Lactarius pubescens</i> Species of fungus

Lactarius pubescens, commonly known as the downy milk cap, is a species of fungus in the family Russulaceae. It is a medium to large agaric with a creamy-buff, hairy cap, whitish gills and short stout stem. The fungus has a cosmopolitan distribution, and grows solitarily or in scattered groups on sandy soil under or near birch.

<i>Lactarius argillaceifolius</i> Species of fungus

Lactarius argillaceifolius is a species of fungus in the family Russulaceae. The mushrooms produced by the fungus have convex to flattened drab lilac-colored caps that are up to 18 cm (7.1 in) wide. The cream-colored gills are closely spaced together and extend slightly down the length of the stem, which is up to 9 cm (3.5 in) long by 3.5 cm (1.4 in) thick. The mushroom produces an off-white latex when injured that stains the mushroom tissue brownish.

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

Cortinarius traganus, also known as the gassy webcap or lilac conifer cortinarius, is a basidiomycete mushroom of the genus Cortinarius. The mushrooms are characterized by their lilac color, the rusty-brown gills and spores, and rusty-brown flesh in the stem.

<i>Mycena maculata</i> Species of fungus in the family Mycenaceae

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.

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

Amanita crocea, the saffron ringless amanita, is a species of Amanita widely distributed in Europe. It is not recommended for consumption due to its similarity to poisonous species of the genus.

<i>Hygrophorus bakerensis</i> Species of fungus

Hygrophorus bakerensis, commonly known as the Mt. Baker waxy cap, the brown almond waxy cap or the tawny almond waxy cap, is a species of fungus in the family Hygrophoraceae. It is characterized by its medium to large, relatively slender-statured fruit bodies with an almond odor, and growth often on or near rotting conifer wood. The slimy cap is brown in the center and cream to white near its curved edges. The gills and the stem are white, and in moist environments are often covered with droplets of a translucent liquid. The mushroom is known only from the United States, where it is common in coniferous forests throughout the Pacific Northwest. It was initially collected in Washington State on Mount Baker, a volcano. Although edible, the mushroom is not considered to be of high quality.

<i>Collybia tuberosa</i> Species of fungus

Collybia tuberosa, commonly known as the lentil shanklet or the appleseed coincap, is an inedible species of fungus in the family Tricholomataceae, and the type species of the genus Collybia. Like the two other members of its genus, it lives on the decomposing remains of other fleshy mushrooms. The fungus produces small whitish fruit bodies with caps up to 1 cm (0.4 in) wide held by thin stems up to 5 cm (2.0 in) long. On the underside of the cap are closely spaced white gills that are broadly attached to the stem. At the base of the stem, embedded in the substrate is a small reddish-brown sclerotium that somewhat resembles an apple seed. The appearance of the sclerotium distinguishes it from the other two species of Collybia, which are otherwise very similar in overall appearance. C. tuberosa is found in Europe, North America, and Japan, growing in dense clusters on species of Lactarius and Russula, boletes, hydnums, and polypores.

<i>Collybia cirrhata</i> Species of fungus

Collybia cirrhata is a species of fungus in the family Tricholomataceae of the order Agaricales. The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to 11 mm in diameter, narrow white gills, and slender whitish stems 8–25 mm long and up to 2 mm (0.08 in) thick. C. cirrhata can be distinguished from the other two members of Collybia by the absence of a sclerotium at the base of the stem. The mushroom is of unknown edibility.

<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. 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 (4–7 in) long and 1–2 cm 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".

<i>Aureoboletus russellii</i> Species of fungus

Aureoboletus russellii, commonly known as the Russell's bolete, or jagged-stemmed bolete, is a species of bolete fungus in the family Boletaceae. An edible species, it is found in Asia and eastern North America, where it grows in a mycorrhizal association with oak, hemlock, and pine trees. Fruit bodies of the fungus are characterized by their coarsely shaggy stem. The yellow-brown to reddish-brown caps are initially velvety, but become cracked into patches with age.
