Cousin of Rosé-des-Prés, the Agaric of Devon, Agaricus devoniensis, expands on the sand of the Mediterranean or Atlantic coast. This common Basidiomycete of the Agaricaceae family particularly appreciates the gray dunes from which its round, unchanging white hat emerges.
Description of the Devon Agaric
The hat of the Devon Agaric is hemispherical, it subsequently has a convex shape and then it eventually spreads out. Small in size, this fleshy hat of an immaculate white in young subjects, turning gray-whitish with age, measures between 3 and 6 cm in diameter. The cuticle comes off easily. The margin, also white, is strongly rolled up then it unwinds at the same time as the fungus grows and spreads out. Hairy veil remnants may remain at the end of this margin. The blades are free and tight, pinkish-white at first, then pinkish and finally brownish as it dries, with age.
the white foot unchanging is stocky and hairless. Slightly radicating, it presents at its base like a small root. He wears multiple intermediate rings, thin and fragile, which quickly disappear. The fleshy flesh is thick and firm, it is whitish and relatively unchanging. Its smell and flavor are pleasant, fungal.
Determination of Agaricus devoniensis
The typical habitat ofAgaricus devoniensis within stabilized gray dunes makes it possible to remove a good number of confusions with other grayish-white Agarics with different living environments. Such as l’Agaric bispore, Agaricus bisporus which thrives on fatty soils (manure, compost), in gardens or parks.
However, a few species thrive in the same type of habitat. This is the case of the Agaric of the sands, Agaricus menieri one of the poisonous dune species, whose flesh turns yellow to the touch, especially at the base of the foot.
The Agaric volvaceous cypress, Agaricus gennadii whose armil, resembling a sock sheathing the foot, is very visible. This species is rare and grows mainly in sandy areas under cypress trees.
Living environment of the Devon Agaric
A common species, the Devon Agaric is found in coastal areas within unforested dunes but sometimes under cypress trees. It grows mainly on stabilized gray dunes, often in moss and lichen mats. It is seen in small groups of individuals or sometimes alone. The most favorable period for its development stretches from spring to winter.
This Agaric is edible more of possible confusion with poisonous mushrooms even fatalities from the dunes hardly encourage its consumption.
Uses of the Devon Agaric
Not listed but culinary, probably to complement starters or main courses.
Species and varieties of Agaricus
Among the Agarics specific to sandy soils, a few are toxic:
- Agaricus freirei : Freire’s agaric, mechular hat, greyish-brown on a pale background, in the wooded dunes of the coast
- Agaricus menieri : Sand agaric, white to greyish cap, in white dunes
- Agaricus pseudopratensis : False Meadow Agaric, grayish-white mechular hat, in fixed dunes
- Agaricus purpurellus : Amethyst agaric, wine-pink to wine-brown cap, under conifers, especially under pines and sometimes on sandy soil
