Tricholoma columbetta, commonly known as dove-coloured tricholoma, is an edible mushroom [1] of the large genus Tricholoma . It is found in Europe, where it is eaten in France.

Genus

Elias Magnus Fries described the species in 1821 as Agaricus columbetta. [2] Paul Kummer placed it in the genus Tricholoma in 1871, within which it is classified in the Section Albata. [3]

Description

The fruit body (mushroom) is white or ivory-coloured, sometimes with a pale ochre tinge in the centre of the cap or pinkish, [4] violet-blue or greenish spots. [5] The cap is conical in young specimens, expanding to convex or flattish with a wavy margin, and is 4–10 cm in diameter. It can be a little sticky when wet. The centre of the cap may have a small boss or be depressed. The gills are adnate and widely spaced. The cylindrical stalk is 614 cm tall and 0,82 cm thick, and has no ring. The mushroom has a mealy smell, which is stronger when it is cut. The spore print is white. The spores are 57.5 x 3.55.5 μm. [4] Tricholoma columbetta is edible, with a pleasant taste. [6]

Tricholoma albidum is similar but stains yellow when cut or bruised. [4] T. columbetta could be confused with paler specimens of the poisonous Entoloma lividum , though the latter has a more grey-white cap, yellow or pink gills. [6]

Distribution

Widespread across Europe, Tricholoma columbetta forms mycorrhizal relationships with oak ( Quercus ) and is found in woodlands, parks, and rarely sand dunes on sandy mildly acidic soils. Mushrooms appear from August to November. [4] In southern Finland, mushrooms appear in August and September. [7]

In 2010, Roger Phillips reported what "seems to be a first record of this species in North America." [1]

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

Clitocybe nuda, commonly known as the blewit or wood blewit and alternately described as Lepista 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.

<i>Calocybe gambosa</i> Species of fungus

Calocybe gambosa, commonly known as St. George's mushroom, is an edible mushroom that grows mainly in fields, grass verges and roadsides. Deriving its common name from when it first appears in the UK, namely on St George's Day. It appears in March in Italy, a warmer country where it is also a popular mushroom to eat, and is known there as prugnolo. It is also popular in Northern Spain and Southern France, in the Basque Country region and its surroundings where it appears in April. In these regions it is usually eaten sautéed with egg or with bacon.

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

Tricholoma equestre or Tricholoma flavovirens, commonly known as the man on horseback or yellow knight is a widely eaten but arguably toxic fungus of the genus Tricholoma that forms ectomycorrhiza with pine trees.

<i>Tricholoma pardinum</i> Species of agaric fungus endemic to North America, Europe, and parts of Asia

Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. It is generally found in beech woodland in summer and autumn. Two subspecies have been described from southern Europe. First officially described by Christiaan Hendrik Persoon in 1801, T. pardinum has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides.

<i>Clitocybe nebularis</i> Species of fungus

Clitocybe nebularis or Lepista nebularis, commonly known as the clouded agaric, cloudy clitocybe, or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from mid to late autumn, it is edible, but may cause gastrointestinal issues.

<i>Hygrocybe coccinea</i> Species of fungus

Hygrocybe coccinea, sometimes called the scarlet hood, scarlet waxcap or righteous red waxy cap, is a colourful member of the mushroom genusHygrocybe. These waxcaps are found across the Northern Hemisphere from China and Japan to Europe and North America. The small bright red mushroom is a familiar sight in unimproved grasslands in Europe in late summer and autumn, and woodlands in North America in winter.

<i>Hygrocybe miniata</i> Species of fungus

Hygrocybe miniata, commonly known as the vermilion waxcap or miniature waxy cap, is a small, bright red or red-orange mushroom of the waxcap genus Hygrocybe. It is a cosmopolitan species, that is found worldwide. In Europe, it is found in fields, on sandy heaths, or grassy commons in the autumn. It is found in rainforest and eucalypt forest as well as heathland in Australia.

<i>Inocybe geophylla</i> Species of fungus

Inocybe geophylla, commonly known as the earthy inocybe, common white inocybe or white fibercap, is a poisonous mushroom of the genus Inocybe. It is widespread and common in Europe and North America, appearing under both conifer and deciduous trees in summer and autumn. The fruiting body is a small all-white or cream mushroom with a fibrous silky umbonate cap and adnexed gills. An all-lilac variety lilacina is also common.

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

Lactarius vietus is a species of fungus in the family Russulaceae, first described by Elias Magnus Fries. It produces moderately sized and brittle mushrooms, which grow on the forest floor or on rotting wood. The flattened-convex cap can vary in shape, sometimes forming the shape of a wide funnel. It is typically grey, but the colour varies. The species has crowded, light-coloured gills, which produce white milk. The spore print is typically whitish, but also varies considerably. The mushrooms typically have a strong, acrid taste and have been described as inedible, but other authors have described them as consumable after boiling. L. vietus feeds by forming an ectomycorrhizal relationship with surrounding trees, and it favours birch. It grows in autumn months and is fairly common in Europe, North America and eastern Asia.

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

Tricholoma terreum, commonly known as the grey knight or dirty tricholoma, is a grey-capped mushroom of the large genus Tricholoma. It is found in coniferous woodlands in Europe, and has also been encountered under introduced pine trees in Australia and New Zealand. It is regarded as edible. A 2014 article speculated that it may be poisonous, but Sitta et al. in 2016 published in the same journal a counter article demonstrating the unfounded nature of such speculation.

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

Russula fragilis, commonly known as the fragile russula, or fragile brittlegill, is a species of mushroom of the genus Russula, whose members are commonly known as brittlegills.

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