Tricholoma argyraceum is a grey-capped mushroom of the large genus Tricholoma . [1] It has been often confused with the similar-looking Tricholoma scalpturatum . [2]
French mycologist Pierre Bulliard described this species as Agaricus argyraceus in 1779, before his countryman Claude Casimir Gillet gave it its current name in 1874. The generic name derives from the Greek trichos/τριχος 'hair' and loma/λωμα 'hem', 'fringe' or 'border'. [3] It lies within the section Terrea within the subgenus Tricholoma within the genus Tricholoma . [4]
The cap is conical initially and flattening to a convex shape, with a prominent boss. Measuring 1.5 to 6 cm (0.59 to 2.36 in) in diameter, it is covered with greyish scales, paler than other grey-capped tricholomas, and the crowded gills are white or pale grey and emarginate or adnate in cross section. They sometimes stain yellowish when bruised. The thin flesh is cream or white and has a farinaceous (floury) and somewhat rancid taste and smell. The whitish stipe is 2–5 cm (0.79–1.97 in) high and 0.3–0.8 cm (0.12–0.31 in) wide and has no ring and a tapering base. [4]
The poisonous T. pardinum is similar in appearance but with coarser scales on its cap. [5] T.scalpturatum has a darker cap without a boss. [4]
Tricholoma argyraceum occurs across Europe but is uncommon overall. The fruit bodies appear from June to December (occasionally earlier in Spring). The species has an ectomycorrhizal association with a number of genera – birch ( Betula ), Carpinus , oak ( Quercus ) and Tilia . [4]
Obsolete synonyms for Tricholoma argyraceum include: [6]
Tricholoma argyraceum is technically edible but of poor quality and inferior to other grey-capped Tricholomas. [7] It has also been classified as inedible. [8]
Agaricus bisporus, commonly known as the cultivated mushroom, is an edible basidiomycete mushroom native to grasslands in Eurasia and North America. It has two color states while immature – white and brown – both of which have various names, with additional names for the mature state.
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.
Leratiomyces ceres, commonly known as the Redlead Roundhead, is mushroom which has a bright red to orange cap and dark purple-brown spore deposit. It is usually found growing gregariously on wood chips and is one of the most common and most distinctive mushrooms found in that habitat. It is common on wood chips and lawns in North America, Europe, Australia, New Zealand and elsewhere. The name Stropharia aurantiaca has been used extensively but incorrectly for this mushroom.
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.
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 late summer to late autumn, it is edible, but may cause gastrointestinal issues.
Lepiota brunneoincarnata, the deadly dapperling, is a gilled mushroom of the genus Lepiota in the order Agaricales. Widely distributed in Europe and temperate regions of Asia as far east as China, it grows in grassy areas such as fields, parks and gardens, and is often mistaken for edible mushrooms. The mushroom has a brown scaled cap up to 4 cm wide with a pinkish brown stem and white gills. It is highly toxic, with several deaths having been recorded as it resembles the edible grey knight and fairy ring champignon.
Lactarius blennius is a medium-sized mushroom of the genus Lactarius found commonly in beech forests in Europe, where it is mycorrhizal, favouring the European beech. It was first described by Elias Magnus Fries. Though its colour and size vary, it is distinctive because it is slimy when wet and exudes copious amounts of milk. It has been the subject of some chemical research, and it can be used to produce pigments and blennins. Blennins, some of which have shown potential medical application, are derived from lactarane, a chemical so named because of their association with Lactarius. The edibility of L. blennius is uncertain, with different mycologists suggesting that it is edible, inedible or even poisonous.
Gomphidius glutinosus, commonly known as the slimy spike-cap, is a gilled mushroom found in Europe & North America. Although it has gills, it is a member of the order Boletales, along with the boletes. The fruiting bodies sprout in pine, fir and spruce woodland in Europe in autumn. Initially, are completely covered with a slimy veil, breaking through to reveal a greyish or brownish-capped mushroom with decurrent greyish gills which sometimes resembles a child's top. Opinions differ on the suitability of this mushroom for the table, some guides hold it in high regard, while others view it with caution.
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.
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.
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.
Agaricus silvaticus, 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.
Tricholoma columbetta, commonly known as dove-coloured tricholoma, is an edible mushroom of the large genus Tricholoma. It is found in Europe, where it is eaten in France.
Tricholoma album, commonly known as the white knight, is an all-white mushroom of the large genus Tricholoma. It is found in Europe, India, and possibly North America. The cap and gills are white. The whitish stipe has no ring.
Tricholoma portentosum, commonly known as the charbonnier, streaked tricholoma, or sooty head, in North America, is a grey-capped edible mushroom of the large genus Tricholoma. It is found in woodlands in Europe and North America.
Tricholoma orirubens, commonly known as blushing tricholoma, is an edible gilled mushroom native to Europe. The grey-capped fruit bodies are generally found singly or in small groups in deciduous and coniferous woodland in autumn.
Tricholoma myomyces is a mushroom of the agaric genus Tricholoma, usually considered to be a synonym of Tricholoma terreum. The species was first described scientifically by Christian Hendrik Persoon in 1794 as Agaricus myomyces, and later transferred to the genus Tricholoma by Danish mycologist Jakob Emanuel Lange in 1933. It is found in Europe and northern North America.
Tricholoma atrosquamosum, commonly known as dark-scaled knight, is an edible gilled mushroom native to Europe. The grey-capped fruit bodies are generally found singly or in small groups in deciduous woodland on chalk-based soils.
Tricholoma vaccinum, commonly known as the russet scaly tricholoma, the scaly knight, or the fuzztop, is a fungus of the agaric genus Tricholoma. It produces medium-sized fruit bodies (mushrooms) that have a distinctive hairy reddish-brown cap with a shaggy margin when young. The cap, which can reach a diameter of up to 6.5 cm (2.6 in) wide, breaks up into flattened scales in maturity. It has cream-buff to pinkish gills with brown spots. Its fibrous, hollow stipe is white above and reddish brown below, and measures 4 to 7.5 cm long. Although young fruit bodies have a partial veil, it does not leave a ring on the stipe.
Tricholoma ustale, commonly known as the burnt knight, is a species of mushroom in the large genus Tricholoma. It is found in Asia, Europe, and North America, though those from North America may represent one or more different species.
