Lactarius sanguifluus, commonly known as the bloody milk cap, is a species of fungus in the family Russulaceae.
 First described from France in 1811, the species was given its current name by Elias Fries in 1838 when he transferred it to "Lactarius".
 Found in Asia, Mediterranean Africa, and Europe, fruit bodies (mushrooms) grow scattered or in groups on the ground under conifers, especially Douglas fir.
 When bruised or cut, the fruit bodies ooze a blood-red to purple latex that slowly turns greenish upon exposure to air.
 The caps are orangish to reddish-brown, and become funnel-shaped with age.
 The gills are pinkish to purplish.
 Different forms have been described from Italy, but these are not universally accepted as distinct.
 "L. sanguifluus" mushrooms are edible, and sold in rural markets of Europe and Asia.
 Fruit bodies grown in polluted soil, including roadsides subject to heavy traffic, can bioaccumulate toxic heavy metals.
 Several sterols and pigment have been isolated and identified from the mushrooms.
Cortinarius is a genus of mushrooms.
 It is suspected to be the largest genus of agarics, containing over 2000 different species and found worldwide.
 A common feature among all species in the genus "Cortinarius" is that young specimens have a cortina (veil) between the cap and the stem, hence the name, meaning "curtained".
 Most of the fibers of the cortina are ephemeral and will leave no trace once gone, except for limited remnants on the stem in some species.
 All have a rusty brown spore print.
 The common names cortinar and webcap refer to members of the genus.
 Due to dangerous toxicity of several species (such as "Cortinarius orellanus") and the fact that it's difficult to distinguish between various species of the genus, non-expert consumption of mushrooms from the genus is discouraged.
Chicken marsala is an Italian-American dish made from chicken cutlets, mushrooms, and Marsala wine.
 It is a variation of traditional Italian "scaloppina" dishes, of which there are many varieties throughout Italy.
 The dish dates to the 19th century, when it most likely originated with English families who lived in western Sicily, where Marsala wine is produced.
 The chicken is coated in flour, briefly sautéed, and then removed from the pan, which is then used to make a Marsala reduction sauce.
 The sauce is made by reducing the wine to nearly the consistency of a syrup while adding onions or shallots, as well as mushrooms, herbs and possibly other ingredients.
 The sauce is then poured over the chicken, which has been kept in a warming oven, and served immediately.

Gymnopilus maritimus is a fungus species of the family Cortinariaceae first collected in northern Sardinia, Italy, in 2006.
 The species produces moderately sized, sturdy mushrooms of a reddish-orange colour.
 The cap, which can measure up to 70 mm across, is covered in orange fibrils, and sometimes has small scales.
 The yellowish stem measures up to 110 mm in length by 8 mm in width, and sometimes shows remnants of the partial veil.
 The mushrooms have thick gills of a variable colour, ranging from yellow to rust but staining darker, and the yellow flesh has a mild taste.
 The mushrooms leave a rusty-brown spore print, while the spores themselves measure from 7.5 - in length.
 The species is most similar in appearance to "G. arenophilus" and "G. fulgens", but can be differentiated from both morphologically.
 Despite the similarities, it is not closely related to either, suggesting convergent evolution.
 Instead, within the genus "Gymnopilus", it is most closely related to the "spectabilis–imperialis" clade.
 However, it is not particularly similar to any of its closest relatives.
Italy in a Day - Un giorno da italiani is a 2014 Italian-British documentary film directed by Gabriele Salvatores.
 It was part of the Out of Competition section at the 71st Venice International Film Festival.
Mycena galericulata is a mushroom species commonly known as the common bonnet, the toque mycena, or the rosy-gill fairy helmet.
 The type species of the genus "Mycena" was first described scientifically in 1772, but was not considered a "Mycena" until 1821.
 It is quite variable in color, size, and shape, which makes it somewhat difficult to reliably identify in the field.
 The mushrooms have caps with distinct radial grooves, particularly at the margin.
 The cap's color varies from grayish brown to dark brown and the shape ranges from bell-like to bluntly conical to flattened with an umbo.
 The stem is hollow, white, tough and thin, without a ring and often roots deeply into the wood on which it grows.
 The gills are white to grayish or even pinkish when mature and are connected by distinct cross-veins.
 The caps can reach 4 cm in diameter, and have a mealy odor and taste.
 The spore print is white and the gills are pink at maturity, which can lead to possible confusion with species of the "Pluteus" genus.
 "M. galericulata" mushrooms grow mostly in clusters on the well-decayed stumps of deciduous and coniferous trees from spring to autumn.
 The species can generally be considered inedible.
 It is common and widespread in the entire temperate zone of the Northern Hemisphere, but it has also been reported from Africa.
Psilocybin mushrooms, also known as psychedelic mushrooms, are a polyphyletic group of mushrooms that contain the psychedelic compounds psilocybin, psilocin and baeocystin.
 Common colloquial terms include magic mushrooms and shrooms.
 They are used mainly as an entheogen and recreational drug whose effects can include euphoria, altered thinking processes, closed and open-eye visuals, synesthesia, an altered sense of time and spiritual experiences.
 Biological genera containing psilocybin mushrooms include "Copelandia", "Galerina", "Gymnopilus", "Inocybe", "Mycena", "Panaeolus"," Pholiotina", "Pluteus", and "Psilocybe".
 Over 100 species are classified in the genus "Psilocybe".
Leccinum manzanitae is an edible species of bolete fungus in the family Boletaceae.
 Described as new to science in 1971, it is commonly known as the manzanita bolete for its usual mycorrhizal association with manzanita trees.
 Its fruit bodies (mushrooms) have sticky reddish to brown caps up to 20 cm , and its stipes are up to 16 cm long and 3.5 cm thick.
 They have a whitish background color punctuated with small black scales known as "scabers".
 Found only in the Pacific Northwest region of the United States and Canada, it is the most common "Leccinum" species in California.
 The mushroom is edible, although opinions vary as to its quality.
 "L. manzanitae" can be usually distinguished from other similar bolete mushrooms by its large size, reddish cap, dark scabers on a whitish stipe, and association with manzanita and madrone.
Diri ak djon djon (Haitian Creole for rice with mushrooms ) is a native dish of Haiti.
 It is essentially a meal consisting of rice (diri, French: "du riz" ) with (ak, French: "avec" ) edible black mushrooms (djon djon).
 The meal is more common in the northern region of the country and therefore can be considered a regional delicacy.
 When the mushrooms are boiled, they release a grayish-black coloring giving the rice its gray color and the dish's distinctive flavor.
 The dish is often served with some sort of meat whether it be fish, chicken or shrimp (usually mixed in the rice).
