Clitopilus prunulus, commonly known as the miller or the sweetbread mushroom, [1] is an edible pink-spored basidiomycete mushroom found in grasslands in Europe and North America. [2] Growing solitary to gregarious in open areas of conifer/hardwood forests; common under Bishop pine ( Pinus muricata ) along the coast north of San Francisco; fruiting shortly after the fall rains. It has a grey to white cap and decurrent gills.
Tyrolean naturalist Giovanni Antonio Scopoli described the miller as Agaricus prunulus in 1772. [3] French mycologist Pierre Bulliard called it Agaricus orcella in 1793. German botanist Paul Kummer erected the genus Clitopilus and gave the miller its current name in 1871. [4] C. prunulus is the type species of the genus, the limits of which have been redefined more than once. [5]
Populations from Yunnan and Taiwan previously considered consistent with C. prunulus were described as a separate species— Clitopilus amygdaliformis —in 2007. [6]
Its common names—the miller, and sweetbread mushroom—are derived from its distinctive smell.
The cap is initially convex when young, but in maturity flattens out, usually with a shallow central depression; the margin is often inrolled. [7] The cap ranges from white to light gray or yellow. It has a characteristic feel similar to the touch of chamois skin, usually being dry, [7] but is sticky when moist. It measures 2 to 10 cm (3⁄4 to 3+7⁄8 in) in diameter. The gills are decurrent in attachment to the stipe, spaced together rather closely, and whitish, although they often develop a pinkish hue in age. [7] The stipe is 2 to 8 cm (3⁄4 to 3+1⁄8 in) long × 4–15 mm thick, and white or sometimes grayish; [8] it may be located off-center or enlarged at the base. [7] The mushroom has a mealy odor, somewhat like cucumber. [9] The spore print is pink. Spores are 9–12 × 5–6.5 μm. [10] Scopoli described it smelling like freshly ground flour. C. prunulus may be found growing on the ground in hardwood and coniferous woods [7] in the summer and autumn.
The variant C. prunulus var. orcellus has a slimy cap and white colors.
C. prunulus has been recorded from Varsey Rhododendron Sanctuary in Sikkim, [11] and from under cork oak in Morocco. [12]
It is found in Valdaysky National Park in Russia. [5]
A specimen identified as C. cf prunulus collected from Kermandie Track in southern Tasmania was related though basal to other collections of the species. [5]
The species is considered edible and choice, [13] but resembles some poisonous species. [8]
The cucumber odor of this species has been attributed to trans-2-nonenal, which is present at a concentration of 17 μg per gram of crushed tissue. [9] C. prunulus contains the volatile compound 1-octen-3-ol, making it unpalatable to the coastal Pacific Northwest banana slug, Ariolimax columbianus . [14]
The poisonous Clitocybe rivulosa (fool's funnel) looks similar. The miller has pink spores whereas those of the fools funnel are white, the gills of the miller are more easily pulled away, and the miller smells of raw pastry. The miller also prefers woodland whereas fool's funnel is a grassland species. [15]
The poisonous Clitocybe dealbata has a similar cap color, but a white spore print. [8]
Clitocybe is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus.
Clitocybe odora, commonly known as the blue green anise mushroom, or aniseed toadstool, is a blue-green mushroom that grows near deciduous and coniferous trees. They can be found growing in small groups along the side of tree roots. This mushroom is edible, but a few expert mushroom hunters insist that young specimens should be avoided as they can be confused with Stropharia aeruginosa. The anise odor is due to the presence of p-anisaldehyde and a small amount of benzaldehyde. This odor can give away the mushroom's presence before it is observed by eye.
Collybia nuda, commonly known as the blewit or wood blewit and previously described as Lepista nuda and Clitocybe 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. This species was reassigned to the genus Collybia in 2023.
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.
Hygrophoropsis aurantiaca, commonly known as the false chanterelle, is a species of fungus in the family Hygrophoropsidaceae. It is found across several continents, growing in woodland and heathland, and sometimes on woodchips used in gardening and landscaping. Fruit bodies (mushrooms) are yellow–orange, with a funnel-shaped cap up to 8 cm across that has a felt-like surface. The thin, often forked gills on the underside of the cap run partway down the length of the otherwise smooth stipe. Reports on the mushroom's edibility vary – it is considered poisonous, but has historically been eaten in parts of Europe and the Americas.
Clitocybe dealbata, also known as the ivory funnel, is a small white funnel-shaped basidiomycete fungus widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, or sweat producing clitocybe, it derives these names from the symptoms of poisoning. It contains potentially deadly levels of muscarine.
Agaricus augustus, known commonly as the prince, is a basidiomycete fungus of the genus Agaricus.
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.
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.
Clitocybe rivulosa, commonly known as the false champignon or fool's funnel, is a poisonous basidiomycete fungus of the large genus Clitocybe. One of several species similar in appearance, it is a small white funnel-shaped toadstool widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, it derives this name from the symptoms of poisoning. It contains potentially deadly levels of muscarine.
Ampulloclitocybe clavipes, commonly known as the club-foot or club-footed clitocybe, is a species of gilled mushroom from Europe and North America. The grey brown mushrooms have yellowish decurrent gills and a bulbous stalk, and are found in deciduous and conifer woodlands. Although considered edible, disulfiram-like reactions have been reported after consumption of alcohol after eating this mushroom.
Agaricus semotus is a woodland mushroom of the fungus order Agaricales. Like many of its relatives, it can be found spread throughout wooded, moist areas in the southern United States, and has been found in areas ranging from California to Florida. It is also indigenous to Great Britain and Europe. A. semotus has also been collected in New Zealand. Although various authors disagree about its edibility, its modest size prevents it from being a significant source of nutrition.
Agaricus placomyces is a toxic basidiomycete fungus of the genus Agaricus. It is found in North America; the Eurasian populations formerly known by the same scientific name are nowadays known as A. moelleri, while the present species may also be referred to as A. praeclaresquamosus.
Aspropaxillus giganteus, also Leucopaxillus giganteus, commonly known as the giant leucopax or the giant funnel, is a saprobic species of fungus in the order Agaricales. As its common names imply, the fruit body, or mushroom, can become quite large—the cap reaches diameters of up to 50 cm (20 in). It has a white or pale cream cap, and is funnel-shaped when mature, with the gills running down the length of the stem. Considered by some to be a choice edible when young, this species has a cosmopolitan distribution, and is typically found growing in groups or rings in grassy pastures, roadside hedges, or woodland clearings. It has been shown to contain a bioactive compound with antibiotic properties.
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.
Infundibulicybe geotropa, also known as the trooping funnel or monk's head, is a funnel-shaped toadstool widely found in Europe and in North America. A large sturdy cream- or buff-coloured funnel-shaped mushroom, it grows in mixed woodlands, often in troops or fairy rings, one of which is over half a mile wide. Although edible, it could be confused with some poisonous species of similar colouration and size.
Clitocybe albirhiza, commonly known as the snowmelt clitocybe, is a species of agaric fungus in the family Tricholomataceae. It is found in high-elevation locations in the western United States.
Paralepista flaccida is a species of mushroom found across the Northern Hemisphere. It is known to form fairy rings.
Infundibulicybe gibba, and commonly known as the common funnel or funnel cap, is a species of gilled mushroom which is common in European woods.
Collybia phyllophila, commonly known as the frosty funnel or the leaf-loving clitocybe, is a fungus in the family Tricholomataceae. Its epithet, meaning leaf-loving comes from its preference for leaf litter. It is common among forests in the Northern Hemisphere, and is poisonous.
