Gliophorus irrigatus is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of slimy waxcap in the UK. [2] The species is widespread in temperate regions, occurring in grassland in Europe and in woodland in North America and elsewhere.

Taxonomy

The species was first described in 1801 by the South African-born mycologist Christiaan Hendrik Persoon as Agaricus irrigatus. It was subsequently combined in a number of different genera, before being transferred to Hygrocybe in 1976. The specific epithet comes from Latin "irrigatus" (= watered or bedewed), with reference to the viscid coating of the fruit bodies. [3]

Molecular research published in 2011, based on cladistic analysis of DNA sequences, showed that Hygrocybe irrigata did not belong in Hygrocybe sensu stricto and it was moved to the genus Gliophorus in 2013. [1] [4]

Description

Basidiocarps are agaricoid, up to 100 mm (4 in) tall, the cap convex at first and remaining convex or becoming flat when expanded, up to 50 mm (2 in) across. The cap surface is very viscid when damp, striate at the margin, and pale greyish brown. The lamellae (gills) are whitish to pale cap-coloured and more or less decurrent (widely attached to and running down the stipe). The stipe (stem) is very viscid when damp, smooth, cylindrical or compressed, and grey to cap-coloured. The spore print is white, the spores (under a microscope) smooth, inamyloid, ellipsoid, about 6.5 to 8.0 by 4.5 to 5.0  μm. [5]

Distribution and habitat

The slimy waxcap has been recorded in Europe, Central and North America, northern Asia, and Australia. [6] Like other waxcaps, it grows in old, unimproved, short-sward grassland (pastures and lawns) in Europe, but in woodland elsewhere. Recent research suggests waxcaps are neither mycorrhizal nor saprotrophic but may be associated with mosses. [7]

Conservation

In Europe, Gliophorus irrigatus is typical of waxcap grasslands, a declining habitat due to changing agricultural practices. The slimy waxcap is one of the commoner species, however, only appearing on the red lists of threatened fungi in a few countries, including the Czech Republic, [8] Germany (Bavaria), [9] and Poland.

Hygrophoraceae Family of fungi

The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics, including Hygrophorus and Hygrocybe species, DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 25 genera and over 600 species. None is of any great economic importance, though fruit bodies of some Hygrocybe and Hygrophorus species are considered edible and may be collected for sale in local markets.

<i>Hygrophorus</i> Genus of fungi

Hygrophorus is a genus of agarics in the family Hygrophoraceae. Called "woodwaxes" in the UK or "waxy caps" in North America, basidiocarps are typically fleshy, often with slimy caps and lamellae that are broadly attached to decurrent. All species are ground-dwelling and ectomycorrhizal and are typically found in woodland. Around 100 species are recognized worldwide. Fruit bodies of several species are considered edible and are sometimes offered for sale in local markets.

<i>Hygrocybe</i> Genus of fungi

Hygrocybe is a genus of agarics in the family Hygrophoraceae. Called waxcaps in English, basidiocarps are often brightly coloured and have waxy to slimy caps, white spores, and smooth, ringless stems. In Europe they are characteristic of old, unimproved grasslands which are a declining habitat, making many Hygrocybe species of conservation concern. Elsewhere they are more typically found in woodlands. Most are ground-dwelling and all are believed to be moss associates. Around 150 species are recognized worldwide. Fruit bodies of several Hygrocybe species are considered edible and are sometimes offered for sale in local markets.

<i>Hygrocybe conica</i>

Hygrocybe conica, commonly known as the witch's hat, conical wax cap or conical slimy cap, is a colourful member of the genus Hygrocybe, found across northern Europe and North America. Originally described as Hygrophorus conicus, it may be a complex of closely related and similar species.

<i>Gliophorus psittacinus</i> Edible mushroom found across Northern Europe

Gliophorus psittacinus, commonly known as the parrot toadstool or parrot waxcap, is a colourful member of the genus Gliophorus, found across Northern Europe. It was formerly known as Hygrocybe psittacina, but a molecular phylogenetics study found it to belong in the genus Gliophorus. It had already been placed in Gliophorus, but it had been considered a synonym of Hygrocybe.

<i>Hygrocybe punicea</i>

Hygrocybe punicea, sometimes called Crimson- or Scarlet Waxy Cap, is a colourful member of the genus Hygrocybe, the waxcaps, found across Northern Europe. Originally described as Hygrophorus puniceus, it is the largest member of the genus.

<i>Porpolomopsis lewelliniae</i> Species of fungus

Porpolomopsis lewelliniae, commonly known as the mauve splitting wax-cap, is a gilled fungus of the waxcap family found in wet forests of eastern Australia and New Zealand. The small mauve- or lilac-coloured mushrooms are fairly common and appear in moss or leaf litter on the forest floor in autumn, and are biotrophic. The key distinguishing feature is the splitting of the cap dividing down the middle of the individual gills.

<i>Hygrocybe coccinea</i>

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 austropratensis</i> Species of fungus

Hygrocybe austropratensis is a gilled fungus of the waxcap family found in a few scattered locations in dry sclerophyll forests in eastern Australia. It is a small mushroom with a 1.4–3 cm diameter pale orange or orange-brown cap and buff-coloured stipe and gills. It is known only from near Sydney, Hazelbrook in the Blue Mountains, and Victoria.

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

Hygrocybe miniata, commonly known as the vermilion waxcap, 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>Gliophorus</i> Genus of fungi

Gliophorus is a genus of agaric fungi in the family Hygrophoraceae. Gliophorus species belong to a group known as waxcaps in English, sometimes also waxy caps in North America or waxgills in New Zealand. The genus was described by Czech mycologist Josef Herink in 1958, but is currently synonymized with Hygrocybe by most standard authorities. It has, however, been adopted in New Zealand which has an unusually large number of native Gliophorus species.

<i>Gloioxanthomyces nitidus</i> Species of fungus

Gloioxanthomyces nitidus, commonly known as the shining waxcap, is a species of fungus in the family Hygrophoraceae. It was originally described by Miles Berkeley and Moses Ashley Curtis in 1853 as a species of Hygrophorus. The specific epithet nitidus means "shining". It was one of two species transferred to the newly created genus Gloioxanthomyces in 2013. Fruitbodies have convex, apricot-yellow to orange caps that are 1–4 cm (0.4–1.6 in) in diameter. The pale yellow, waxy gills are decurrent, with a somewhat distant spacing. Other than the gills and the base of the stipe, the bright coloring of the fruitbody fades with age. Spores are elliptical, smooth, and measure 6–10 by 4–6 µm. It is found in North America, where it grows on the ground in groups in coniferous or mixed forests. It prefers bogs, swamps, and similar moist habitats.

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

Hygrocybe appalachianensis, commonly known as the Appalachian waxy cap, is a gilled fungus of the waxcap family. It is found in the eastern United States, where it fruits singly, in groups, or clusters on the ground in deciduous and mixed forests. The species, described in 1963 from collections made in the Appalachian Mountains, was originally classified in the related genus Hygrophorus. It was transferred to Hygrocybe in 1998, in which it has been proposed as the type species of section Pseudofirmae.
