Agaricus silvaticus

Agaricus silvaticus (or Agaricus sylvaticus), otherwise known as the scaly wood mushroom, blushing wood mushroom, or pinewood mushroom, is a species of mushroom often found in groups in coniferous forests from early summer, or September through to November in Europe, North Africa and North America.

Description

The greyish-brown cap is hemispherical when young, but later flattens out up to 10 cm in diameter. It is covered with broad scales. The gills are grey when young, and become much darker with age. The spores are chocolate brown. The stem is brownish, often with a hanging ring and a small bulb at the base. [1] The flesh is white with a mild taste, turning reddish when cut.

Although one field guide lists the species as edible, [2] another does not recommend it on the basis of its being related to species that cause gastric upset. [3]

Naming

The species name sylvaticus (or silvaticus) means "of the woods". Both spellings are found in the literature, but Species Fungorum gives sylvaticus as the current name and so that version should be preferred. [4] [5]

This well-known species was first validly described under the current name, Agaricus silvaticus, in 1774 by the early mycologist Jacob Christian Schäffer. [5] At that time most gilled mushrooms were all grouped under the genus Agaricus , but later were allocated to new genera which reflected their different characteristics. Now Agaricus has a much more restricted meaning, being the genus of the common cultivated mushrooms of Europe and America, but A. sylvaticus belongs to that group and has kept the same name during all that time. [6]

Similar species

Agaricus haemorrhoidarius is normally considered a synonym, but has also been defined as a separate species, distinguished by its flesh which immediately turns red when cut. Agaricus phaeolepidotus is distinguished by a stem which yellows (in addition to turning pink) when cut. The cap background is browner than A. silvaticus and its smell suggests iodine or ink. Tricholoma vaccinum looks similar from above but has no ring and develops reddish-brown gills.

Chemical tests in mushroom identification are methods that aid in determining the variety of some fungi. The most useful tests are Melzer's reagent and potassium hydroxide.

<i>Agaricus bernardii</i> Agaric fungus in the family Agaricaceae

Agaricus bernardii, commonly called the salt-loving agaricus, or salty mushroom, is an agaric fungus in the family Agaricaceae. The mushroom's thick stem is usually shorter than the diameter of the cap, which ranges from 5–15 centimetres and is convex to flattened. The cap surface is whitish to buff, and can develop scales or warts in age. The gills are initially pink before turning brown when the spores mature. The flesh turns reddish when it is cut or bruised. It resembles species such as A. bitorquis.

<i>Echinoderma asperum</i> Species of fungus

Echinoderma asperum or Lepiota aspera, sometimes known commonly as the freckled dapperling, is a large, brownish, white-gilled mushroom, with a warty or scaly cap. It lives in woodland, or on bark chips in parks, and gardens.

<i>Mycena haematopus</i> Fungus species in the family Mycenaceae widespread and common in Europe and North America

Mycena haematopus, commonly known as the bleeding fairy helmet, the burgundydrop bonnet, or the bleeding Mycena, is a species of fungus in the family Mycenaceae, of the order Agaricales. It is widespread and common in Europe and North America, and has also been collected in old Japan and Venezuela. It is saprotrophic—meaning that it obtains nutrients by consuming decomposing organic matter—and the fruit bodies appear in small groups or clusters on the decaying logs, trunks, and stumps of deciduous trees, particularly beech. The fungus, first described scientifically in 1799, is classified in the section Lactipedes of the genus Mycena, along with other species that produce a milky or colored latex.

<i>Phylloporus rhodoxanthus</i> Species of fungus

Phylloporus rhodoxanthus, commonly known as the gilled bolete, is a species of fungus in the family Boletaceae. Like other species in the genus, it has a lamellate (gilled) hymenium and forms a mycorrhizal association with the roots of living trees, specifically beech and oak in North and Central America.

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

Mycena acicula, commonly known as the orange bonnet, or the coral spring Mycena, is a species of fungus in the family Mycenaceae. It is found in Asia, the Caribbean, North America and Europe. The fruit bodies, or mushrooms, of the fungus grow on dead twigs and other woody debris of forest floors, especially along streams and other wet places. They have small orange-red caps, up to 1 cm (0.4 in) in diameter, held by slender yellowish stems up to 6 cm (2.4 in) long. The gills are pale yellow with a whitish edge. Several other Mycena species look similar, but may be distinguished by differences in size and/or microscopic characteristics. M. acicula is considered inedible because of its small size.

<i>Agaricus deserticola</i> Species of fungus in the family Agaricaceae endemic to southwestern and western North America

Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae. Found only in southwestern and western North America, A. deserticola is adapted for growth in dry or semi-arid habitats. The fruit bodies are secotioid, meaning the spores are not forcibly discharged, and the cap does not fully expand. Unlike other Agaricus species, A. deserticola does not develop true gills, but rather a convoluted and networked system of spore-producing tissue called a gleba. When the partial veil breaks or pulls away from the stem or the cap splits radially, the blackish-brown gleba is exposed, which allows the spores to be dispersed.

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

Mycena californiensis is a species of fungus in the family Mycenaceae. It is a common and abundant species in the coastal oak woodlands of California, where it grows saprobically, feeding on the fallen leaves and acorns of various oak species. First described in 1860 by Berkeley and Curtis, the species was collected four years earlier during an exploring and surveying expedition. It was subsequently considered a doubtful species by later Mycena researchers, until a 1999 publication validated the taxon. Mycena elegantula is considered a synonym.

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

Cortinarius varius, also known as the contrary webcap, is a basidiomycete mushroom of the genus Cortinarius. The mushroom has orangish-yellow caps that reach up to 10 cm (3.9 in) in diameter, and thick club-shaped stems up to 10 cm (3.9 in) long.

<i>Agaricus hondensis</i> Species of fungus in the family Agaricaceae

Agaricus hondensis, commonly known as the felt-ringed agaricus, is a species of fungus in the family Agaricaceae. The species was officially described in 1912 by mycologist William Alphonso Murrill, along with three other Agaricus species that have since been placed in synonymy with A. hondensis. Found in the Pacific Northwest region of North America, A. hondensis fruits in the fall under conifers or in mixed forests.

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

Hygrophorus olivaceoalbus, commonly known as the olive wax cap or sheathed waxy cap, is a species of fungus in the genus Hygrophorus. The fruit bodies (mushrooms) appear from midsummer to late autumn under conifers in North American and Eurasian mountain forests. The mushrooms have olive-brown, slimy caps with dark streaks and a dark umbo; the caps measure 3 to 12 cm in diameter. Other characteristic features include a slimy stem up to 12 cm long that is spotted with ragged scales up to a ring-like zone. As its name implies, the mushroom has a waxy cap and gills. It is native to North America and across the northern regions of Europe. According to a publication by the Council of Europe, the fungus is nearly extinct in France.

<i>Volvariella bombycina</i> Species of mushroom in the family Pluteaceae

Volvariella bombycina, commonly known as the silky volvariella, silky sheath, silky rosegill, silver-silk straw mushroom, or tree mushroom, is a species of edible mushroom in the family Pluteaceae. It is an uncommon but widespread species, having been reported from Asia, Australia, the Caribbean, Europe, and North America. The fruit body (mushroom) begins developing in a thin, egg-like sac. This ruptures and the stem expands quickly, leaving the sac at the base of the stem as a volva. The cap, which can attain a diameter of up to 20 centimetres, is white to slightly yellowish and covered with silky hairs. On the underside of the cap are closely spaced gills, free from attachment to the stem, and initially white before turning pink as the spores mature. The mushroom grows singly or in clusters, often appearing in old knotholes and wounds in elms and maples. V. bombycina contains compounds with antibacterial properties.

Hygrophorus russula, commonly known as the pinkmottle woodwax, false russula, or russula-like waxy cap, is a fungus native to North America and Europe.

<i>Pleurotus cornucopiae</i> Species of fungus

Pleurotus cornucopiae is a species of edible fungus in the genus Pleurotus, It is quite similar to the better-known Pleurotus ostreatus, and like that species is cultivated and sold in markets in Europe and China, but it is distinguished because its gills are very decurrent, forming a network on the stem.

<i>Collybiopsis peronata</i> Species of fungus

Collybiopsis peronata, also known as wood woolly-foot, is a species of gilled mushroom which is common in European woods.
