Description

The cap is 1–7 cm in width. [3]

The gills are purple. [4] The mushroom is edible. [1]

Spores are 7.5–10.5 x 7–16 μm, subglobose or broadly elliptical. The spore print is white.

Similar species

This species is similar to L. amethystina but differs by occurring than hard wood forest and in Eastern North America, rather than conifers forest; having a smaller sporocarp; and being a lighter purple color.[ citation needed ] L. bicolor is smaller and less purplish; L. laccata has whitish mycelium at its base. [5] Cortinarius violaceus is darker and has a less fibrillose stipe. [5]

<i>Hypholoma fasciculare</i> Species of fungus

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 saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.

<i>Russula xerampelina</i> Species of fungus

Russula xerampelina, also commonly known as the shrimp russula, crab brittlegill, or shrimp mushroom, is a basidiomycete mushroom of the brittlegill genus Russula. Two subspecies are recognised. The fruiting bodies appear in coniferous woodlands in autumn in northern Europe and North America. Their caps are coloured various shades of wine-red, purple to green. Mild tasting and edible, it is one of the most highly regarded brittlegills for the table. It is also notable for smelling of shellfish or crab when fresh.

<i>Laccaria laccata</i> Species of fungus

Laccaria laccata, commonly known as the deceiver, lackluster laccaria, or waxy laccaria, is a white-spored species of small edible mushroom found throughout North America and Europe. It is a highly variable mushroom, and can look quite washed out, colorless and drab, but when younger it often assumes red, pinkish brown, and orange tones. The species is often considered by mushroom collectors to be a 'mushroom weed' because of its abundance and plain stature.

<i>Collybia nuda</i> Species of mushroom

Collybia nuda, commonly known as the blewit or wood blewit and previously described as Lepista nuda and Clitocybe nuda, is an edible mushroom native to Europe and North America. Described by Pierre Bulliard in 1790, it was also known as Tricholoma nudum for many years. It is found in both coniferous and deciduous woodlands. It is a fairly distinctive mushroom that is widely eaten. It has been cultivated in Britain, the Netherlands and France. This species was reassigned to the genus Collybia in 2023.

Tricholomopsis rutilans, commonly known as plums and custard, or red-haired agaric, is a species of gilled mushroom found across Europe and North America.

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

Gymnopilus sapineus, commonly known as the scaly rustgill or common and boring gymnopilus, 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>Clitopilus prunulus</i> Species of fungus

Clitopilus prunulus, commonly known as the miller or the sweetbread mushroom, is an edible pink-spored basidiomycete mushroom found in grasslands in Europe and North America. Growing solitary to gregarious in open areas of conifer/hardwood forests; common under Bishop pine along the coast north of San Francisco; fruiting shortly after the fall rains. It has a grey to white cap and decurrent gills.

<i>Craterellus tubaeformis</i> Species of fungus

Craterellus tubaeformis is an edible fungus, also known as yellowfoot, winter mushroom, or funnel chanterelle. It was reclassified from Cantharellus, which has been supported by molecular phylogenetics.

<i>Cortinarius violaceus</i> Species of fungus native to the Northern Hemisphere

Cortinarius violaceus, commonly known as the violet webcap or violet cort, is a fungus in the webcap genus Cortinarius native across the Northern Hemisphere. The fruit bodies are dark purple mushrooms with caps up to 15 cm (6 in) across, sporting gills underneath. The stalk measures 6 to 12 centimetres by 1 to 2 cm, sometimes with a thicker base. The dark flesh has a smell reminiscent of cedar wood. Forming symbiotic (ectomycorrhizal) relationships with the roots of various plant species, C. violaceus is found predominantly in conifer forests in North America and deciduous forests in Europe.

<i>Laccaria amethystina</i> Species of fungus

Laccaria amethystina, commonly known as the amethyst deceiver, or amethyst laccaria, is a small brightly colored mushroom, that grows in deciduous and coniferous forests. The mushroom itself is edible, but can absorb arsenic from the soil. Because its bright amethyst coloration fades with age and weathering, it becomes difficult to identify, hence the common name "deceiver". This common name is shared with its close relation Laccaria laccata that also fades and weathers. It is found mainly in Northern temperate zones, though it is reported to occur in tropical Central and South America as well. Recently, some of the other species in the genus have been given the common name of "deceiver".

<i>Suillus brevipes</i> Species of edible fungus in the family Suillaceae found throughout North America

Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm, while the stipe is up to 6 cm long and 2 cm thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.

<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>Plectania nannfeldtii</i> Species of fungus

Plectania nannfeldtii, commonly known as Nannfeldt's Plectania, the black felt cup, or the black snowbank cup fungus, is a species of fungus in the family Sarcosomataceae. The fruit bodies of this species resemble small, black, goblet-shaped shallow cups up to 3 cm wide, with stems up to 4 cm long attached to black mycelia. Fruit bodies, which may appear alone or in groups on the ground in conifer duff, are usually attached to buried woody debris, and are commonly associated with melting snow. Plectania nannfeldtii is found in western North America and in Asia, often at higher elevations. Similar black cup fungi with which P. nannfeldtii may be confused include Pseudoplectania vogesiaca, P. nigrella, and Helvella corium.

<i>Russula integra</i> Species of fungus

Russula integra, commonly known as the entire russula, is a species of mushroom. The fungus stems from the huge genus of Russula. It is found in conifer forests across Europe and throughout North America. The fruiting body is mildly flavoured with a slight cashew-like taste and dense flesh. It is edible and most commonly consumed in Central Europe.

<i>Sarcoscypha occidentalis</i> Species of fungus

Sarcoscypha occidentalis, commonly known as the stalked scarlet cup or the western scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the Pezizales order. Phylogenetic analysis has shown that it is most closely related to other Sarcoscypha species that contain large oil droplets in their spores. S. occidentalis has an imperfect form, classified as Molliardiomyces occidentalis.

<i>Pholiota squarrosa</i> Species of fungus

Pholiota squarrosa, commonly known as the shaggy scalycap, the shaggy Pholiota, or the scaly Pholiota, is a species of mushroom in the family Strophariaceae. Common in North America and Europe, it is a secondary parasite, in that it attacks trees that have already been weakened from prior injury or infection by bacteria or other fungi. It has a wide range of hosts among deciduous trees, although it can also infect conifers. It can also live as a saprobe, deriving nutrients from decomposing wood.

<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 in diameter atop a slender stem up to 8 cm 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>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>Thelephora palmata</i> Species of clavarioid fungus

Thelephora palmata commonly known as the fetid false coral or stinking earthfan, is a species of clavarioid fungus in the family Thelephoraceae. The fruit bodies are leathery and coral-like, with branches that are narrow at the base before widening out like a fan and splitting into numerous flattened prongs. The wedge-like tips are whitish when young, but darken as the fungus matures. The common names of the fungus refers to its pungent odor, likened to fetid garlic. A widely distributed but uncommon species, it is found in Asia, Australia, Europe, North America, and South America, where it fruits on the ground in both coniferous and mixed forest.

<i>Ramaria stricta</i> Species of fungus

Ramaria stricta, commonly known as the strict-branch coral or strict coral mushroom, is a coral fungus of the genus Ramaria. It has a cosmopolitan distribution, and grows on dead wood, stumps, trunks, and branches of both deciduous and coniferous trees. Its fruit body is up to 10 cm tall, made of multiple slender, compact, and vertical parallel branches. Its color is typically light tan to vinaceous-brown. All parts of the mushroom will bruise when handled. There are several lookalike corals that can usually be distinguished from R. stricta by differences in coloration, bruising reaction, or microscopic features. The fungus is inedible due to its unpleasant odor and bitter taste.
