Candolleomyces candolleanus (formerly known as Psathyrella candolleana) is a mushroom in the family Psathyrellaceae. It is commonly found growing in small groups around stumps and tree roots on lawns and pastures [2] in Europe and North America. In 2014, it was reported from Iraq. [3] The coloring varies between white and golden brown.

Description

The cap is tan when young, [2] growing to 2–8 cm (1–3 in) in diameter, [4] initially conical, later becoming rounded and finally with upturned margins in maturity. The cap margin is irregular and radially asymmetrical—a defining characteristic of this species. It can retain veil fragments on the edge and center. [2] The white stalk [2] is 4–10 cm (1.5–4 in) tall and 3–7 mm wide. [4] The spore print is purple-brown, while spores are smooth and elliptical, measuring 6.5–8 by 4–5  μm. [5]

Etymology

The specific epithet candolleanus honors Swiss botanist Augustin Pyramus de Candolle. [6]

Edibility

While it is edible and may have a good flavor, it is not recommended due to its thin flesh, alleged poor culinary value and consistency, as well as difficulty in identification. [2] [7] [8]

Similar species

One similar species is Psathyrella gracilis . [4] Some species may have darker caps when young, drying to match that of C. candolleanus. [2]

<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>Pluteus cervinus</i> Species of fungus

Pluteus cervinus, commonly known as the deer shield, deer mushroom, or fawn mushroom, is a species of fungus in the order Agaricales. Fruit bodies are agaricoid (mushroom-shaped). Pluteus cervinus is saprotrophic and fruit bodies are found on rotten logs, roots, tree stumps, sawdust, and other wood waste. The species is common in Europe and eastern North America, but rare and possibly introduced in western North America.

<i>Panaeolus foenisecii</i> Species of fungus

Panaeolus foenisecii, commonly called the mower's mushroom, haymaker, haymaker's panaeolus, or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns and is not an edible mushroom. In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-HTP and 5-hydroxyindoleacetic acid. In many field guides it is listed as psychoactive; however, the mushroom does not produce any hallucinogenic effects.

<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>Marasmius oreades</i> Species of fungus

Marasmius oreades, also known as the fairy ring mushroom, fairy ring champignon or Scotch bonnet, is a mushroom native to North America and Europe. Its common names can cause some confusion, as many other mushrooms grow in fairy rings, such as the edible Agaricus campestris and the poisonous Chlorophyllum molybdites.

<i>Gymnopilus sapineus</i> Species of fungus

Gymnopilus sapineus, commonly known as the scaly rustgill or common and boring gymnopilus, is a small and widely distributed mushroom which grows in dense clusters on dead conifer wood. It has a rusty orange spore print and a bitter taste. This species does not stain blue and lacks the hallucinogen psilocybin.

<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>Craterellus tubaeformis</i> Species of fungus

Craterellus tubaeformis is an edible fungus, also known as yellowfoot, winter mushroom, or funnel chanterelle. It was reclassified from Cantharellus, which has been supported by molecular phylogenetics.

<i>Leucoagaricus leucothites</i> Species of fungus

Leucoagaricus leucothites, commonly known as the smooth parasol, woman on motorcycle, ma'am on motorcycle, white dapperling, or white agaricus mushroom, is a species of agaric fungus. The species was originally described as Agaricus leucothites by Carlo Vittadini in 1835, and bears similarity to species of that genus. Solomon Wasser transferred it to Leucoagaricus in 1977. While sometimes regarded as edible, the species is suspected of being poisonous due to gastric-upset-causing toxins. It could also be confused with the deadly Amanita ocreata.

<i>Stropharia ambigua</i> Species of fungus

Stropharia ambigua, sometimes known as the questionable Stropharia, is a saprotrophic agaric mushroom, commonly fruiting in leaf litter and wood chips in the Pacific Northwest.

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

Hygrophorus subalpinus, commonly known as the subalpine waxycap, is a species of white snowbank fungus in the family Hygrophoraceae. Found in the mountains of western North America, it is found growing on the ground under conifers, usually near snowbanks.

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

Mycena overholtsii, commonly known as the snowbank fairy helmet or fuzzy foot, is a species of fungus in the family Mycenaceae. The mushrooms produced by the fungus are relatively large for the genus Mycena, with convex grayish caps up to 5 cm (2 in) in diameter and stems up to 15 cm (6 in) long. The gills on the underside of the cap are whitish to pale gray, and initially closely spaced before becoming well-spaced at maturity after the cap enlarges. The mushrooms are characterized by the dense covering of white "hairs" on the base of the stem. M. overholtsii is an example of a snowbank fungus, growing on well-decayed conifer logs near snowbanks, during or just after snowmelt. Formerly known only from high-elevation areas of western North America, particularly the Rocky Mountain and Cascade regions, it was reported for the first time in Japan in 2010. The edibility of the mushroom is unknown. M. overholtsii can be distinguished from other comparable species by differences in location, or spore size.

<i>Pholiota flammans</i> Species of fungus

Pholiota flammans, commonly known as the yellow pholiota, the flaming Pholiota, or the flame scalecap, is a basidiomycete agaric mushroom of the genus Pholiota. Its fruit body is golden-yellow in color throughout, while its cap and stem are covered in sharp scales. As it is a saprobic fungus, the fruit bodies typically appear in clusters on the stumps of dead coniferous trees. P. flammans is distributed throughout Europe, North America, and Asia in boreal and temperate regions. Its edibility has not been clarified.

<i>Agrocybe pediades</i> Species of fungus

Agrocybe pediades, commonly known as the common fieldcap or common agrocybe, is a typically lawn and other types of grassland mushroom, but can also grow on mulch containing horse manure. It was first described as Agaricus pediades by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus Agrocybe by Victor Fayod in 1889. A synonym for this mushroom is Agrocybe semiorbicularis, though some guides list these separately. Technically it is edible, but it could be confused with poisonous species, including one of the genus Hebeloma.
