Coprinopsis picacea, commonly known as the magpie mushroom, magpie fungus, or magpie inkcap fungus, is a species of fungus in the family Psathyrellaceae. It was first described in 1785 by French mycologist Jean Baptiste François Pierre Bulliard in 1785 as Agaricus picaceus. [1]

The species can sometimes be confused with the edible Coprinus comatus .

Distribution

The magpie inkcap is common in Europe and Australia. In Europe, the area extends from Great Britain and France in the west to Poland, Hungary and Romania in the east and south to Spain and the Balearic Islands, Italy and Greece and to Germany and Denmark in the north.

Description

The cap is initially egg-shaped, reaching a width of 7 cm. Later it opens up and takes on a bell shape that is up to 8 cm wide. The cap is serrated and colored white on very young mushrooms. It breaks open with increasing age, so that the beige to dark brown background emerges. Remnants of the white, grayish to cream-colored velum remain on the cap as flakes, giving the impression of woodpecker or magpie plumage. With age, the brim of the cap rolls up and dissolves. The lamellae are very close and are initially greyish-white, then pink to gray in color. Eventually they melt, dripping and black, giving it the name inkcap. The stalk is whitish and 12–20 (–30) cm long and 6–15 mm thick. It is hollow and not very stable, slightly tapered towards the top and covered with scales or fine fibers that form a snake towards the base. The flesh is whitish with a fibrous, watery consistency and sometimes has an unpleasant smell of moth powder. The taste is also unpleasant.

The species is inedible and causes digestive upset. [2]

Microscopic features

The elliptical, dark brown spores are 14–18.5 × 10–13 μm in size. The Cheilo- and pleuro Zystiden are bubbles or bag-to tubular. They are up to 150 μm long and 50 μm wide.

<i>Coprinus comatus</i> Species of fungus

Coprinus comatus, commonly known as the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The caps are white, and covered with scales—this is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and deliquesce ('melt') into a black liquid filled with spores. This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.

<i>Entoloma sinuatum</i> Species of poisonous fungus in the family Entolomataceae found across Europe and North America

Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.

<i>Leccinum aurantiacum</i> Species of fungus

Leccinum aurantiacum is a species of fungus in the genus Leccinum found in forests of Eurasia and North America. It has a large, characteristically red-capped fruiting body. In North America, it is sometimes referred to by the common name red-capped scaber stalk. Some uncertainties exist regarding the taxonomic classification of this species in Europe and North America. It is considered edible, but must be cooked thoroughly.

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

Russula adusta, commonly known as the blackening brittlegill or blackening russula, is a species of gilled mushroom. It is found in woodlands of Europe and North America. Russula adusta is a member of the Russula subgenus Compactae. The cap is brown to gray and somewhat shiny, with a mild taste and, reportedly, an odor of empty wine barrels. It has a propensity to turn black from cutting or bruising and has white spores. It can be found growing with conifers. Similar species include Russula albonigra and R. densifolia.

<i>Cortinarius mucosus</i> Species of mushroom

Cortinarius mucosus, commonly known as the orange webcap or the slimy cortinarius, is a species of mushroom in the family Cortinariaceae. In North America, the species is more commonly associated with northern coniferous forests. The specific epithet is derived from the Latin word mucosus, meaning mucus.

<i>Coprinopsis lagopus</i> Species of fungus

Coprinopsis lagopus is a species of fungus in the family Psathyrellaceae. Until 2001, the species was known as Coprinus lagopus; advances in the understanding of phylogenetic relationships between the various coprinoid species led to a major reorganization of that genus. It is a delicate and short-lived fungus, the fruit bodies lasting only a few hours before dissolving into a black ink – a process called deliquescence. The vague resemblance of the young fruit body to the paw of a white rabbit has earned this species the common name harefoot mushroom.

<i>Exidia glandulosa</i> Species of fungus

Exidia glandulosa, commonly known as black witches' butter, black jelly roll, or warty jelly fungus, is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The fruit bodies are up to 3 cm (1.2 in) wide, shiny, black and blister-like, and grow singly or in clusters. Its occurrence elsewhere is uncertain because of confusion with the related species, Exidia nigricans.

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

Tricholoma saponaceum, also known as the soap-scented toadstool, soapy tricholoma, soapy knight or soap tricholoma is an inedible mushroom found in woodlands in Europe and North America.

<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>Lepiota clypeolaria</i> Species of fungus

Lepiota clypeolaria, commonly known as the shield dapperling or the shaggy-stalked Lepiota, is a common 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>Hygrophorus eburneus</i> Species of fungus

Hygrophorus eburneus, commonly known as the ivory waxy cap or the cowboy's handkerchief, is a species of edible mushroom in the waxgill family of fungi. It is widespread in Europe and North America, and has also been collected in northern Africa. The fruit bodies are medium-sized, pure white, and when wet are covered in a layer of slime thick enough to make the mushroom difficult to pick up. The gills are broadly attached to the stem or running down it; as the family name suggests, they feel waxy when rubbed between the fingers. Like all Hygrophorus species, the fungus is mycorrhizal—a symbiotic association whereby the underground fungal mycelia penetrate and exchange nutrients with tree roots. They are common in a variety of forest types, where they grow on the ground in thickets or grassy areas. Hygrophorus eburneus is the type species of the genus Hygrophorus. A number of biologically active chemicals have been purified from the fruit bodies of the fungus, including fatty acids with bactericidal and fungicidal activity.

<i>Coprinopsis variegata</i> Species of fungus

Coprinopsis variegata, commonly known as the scaly ink cap or the feltscale inky cap, is a species of fungus in the family Psathyrellaceae. Distributed in eastern North America, it has a medium-sized, bell-shaped to flattened cap up to 7.5 cm (3.0 in) in diameter, with felt-like, patchy scales. The gills, initially white, turn black in maturity and eventually dissolve into a black "ink". Fruit bodies grow in clusters or groups on leaf litter or rotted hardwood, although the wood may be buried, giving the appearance of growing in the soil. The fungus is found in the United States, in areas east of the Great Plains. Coprinus ebulbosus and Coprinus quadrifidus are names assigned by Charles Horton Peck to what he believed were species distinct from C. variegata; they were later shown to represent the same species, and are now synonyms. The mushroom is not recommended for consumption, and has been shown to cause allergic reactions in susceptible individuals.

<i>Gyroporus cyanescens</i> Species of fungus

Gyroporus cyanescens, commonly known as the bluing bolete or the cornflower bolete, is a species of bolete fungus in the family Gyroporaceae. First described from France in 1788, the species is found in Asia, Australia, Europe, and eastern North America, where it grows on the ground in coniferous and mixed forests.

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

Amanita atkinsoniana, also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. The fruit body is white to brownish, with caps up to 12.5 centimetres in diameter, and stems up to 20 cm long. The surface of the cap is covered with brownish conical warts.

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

Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.

<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>Hygrophorus marzuolus</i> Species of fungus

Hygrophorus marzuolus, commonly known as the March mushroom, is a species of fungus in the family Hygrophoraceae. It is known from Asia, Europe, and North America, where it grows on the ground in mixed forests at high elevations.

<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.

<i>Crepidotus applanatus</i> Species of fungus

Crepidotus applanatus is a species of fungus in the family Crepidotaceae. It was first described in 1796 by Christiaan Hendrik Persoon and renamed by Paul Kummer in 1871. It is inedible.
