Top 20 Most Common Mushrooms in Argentina

The hairy bracket is a polypore that grows on dead hardwoods, with beech trees being a particularly favored host. The species usually grows in solitary, semi-circular shelves that protrude outwards from branches or boles. Although their color is muted, you may still catch sight of them in winter - because they sport tough, leathery bodies, they can persist even after most fruiting mushrooms have faded away for the season.

The mushrooms of the fairy inkcap species have a tendency to congregate in large masses over dead tree stumps and decaying roots. They appear all around the world from early spring all the way to the first frosts, but each fruit only lasts a few days before turning black and distributing its spores.

Just as its Latin and the common English names suggest, the fan-shaped jelly-fungus (Dacryopinax spathularia) is a fan-shaped or spatula-shaped jelly-like mushroom. It commonly grows in wood cracks and it sometimes even appears in the cracks of the processed wood and lumber. Despite the word "jelly" in its name, the fan-shaped jelly-fungus is not considered edible.

Found in many countries around the northern hemisphere, the laughing gym grows on stumps of deciduous trees, and occasionally under conifers. This mushroom is large, firm, and colorful, and appears in small groups. Its scientific name, Gymnopilus junonius, means “naked cap sacred to Juno,” a reference to its distinctive and beautiful appearance. This mushroom is inedible and possibly toxic.

Immature fruiting bodies of L. periphragmoides start as round or oval "eggs" that may be up to 5 cm (2.0 in) in diameter. On the underside of the egg are whitish rhizomorphs that anchor it to the substrate. The peridium is white to buff-colored on the external surface, and has a gelatinous layer inside. An egg cut in half lengthwise reveals internal layers, including a tough white outer peridium, and a thick layer of firm, translucent, gelatinous matter transversed by strands (trabeculae) of denser white tissue. The strands are anastomosing partitions, connecting with the peridium externally and with the bars of the receptaculum within. The gelatinous layer is therefore divided up into many irregular longitudinal chambers. The egg eventually ruptures as the stalk expands and breaks through, creating a volva at the base of the stipe. In maturity, the fruit bodies, are up to 15 cm (5.9 in) tall, with a latticed spherical cap (the receptaculum) atop a long yellow or reddish stipe. In general, Old World specimens tend to be yellow, while New World specimens are reddish, although exceptions have been noted in the literature. The receptaculum is typically 1.5–3.5 cm (0.6–1.4 in) in diameter and forms a red or orange lattice, or mesh. There are typically between 20 and 100 small pentagonal to hexagonal meshes in the receptaculum; the arms of the mesh have sharp ridges on the outer surface, corrugations on the sides, and are flat to weakly ridged on the inner surface. The internal surfaces of the receptaculum are covered with an olive-green spore-bearing gleba, which sometimes seeps through the mesh holes. Like most stinkhorn species, the gleba has a foul odor, comparable to rotten meat, but it is "less-offensive" than most. The smell of fresh, newly exposed gleba has been reported to be sweet, similar to amyl acetate; the foul odor forming only after it has been exposed to air for some time. The stipe is 5–15 cm (2.0–5.9 in) by 0.8–3 cm (0.3–1.2 in) thick, and is hollow and spongy. The walls of the stipe are made of an inner layer of large tubes and two or three outer layers of small tubes. Specimens may occasionally be found with fused heads on two separate stipes arising from a single volva. A variety with a white fruit body is known, Lysurus periphragmoides var. albidum (originally described as Simblum texense var. albidum by Long). It was reported growing from sandy alkaline soil in semi-arid regions of New Mexico, but has not been reported again since Long's collections in 1941. Spores are elliptical or oblong in shape, smooth, inamyloid, and have dimensions of 3.5–4.5 by 1.5–2.5 µm. The use of scanning electron microscopy has revealed that L. periphragmoides (in addition to several other Phallales species) has a hilar scar—a small indentation in the surface of the spore where it was previously connected to the basidium via the sterigma. Like many of the stinkhorns, L. periphragmoides is generally considered only edible when in its immature "egg" form.

Sandy stiltball(Battarrea phalloides) is an unusually tall species of puffball, a family of mushrooms that do not usually have noticeable stalks. Due to declining numbers in the wild, is illegal to pick in certain countries (including Hungary and the United Kingdom). Its edibility remains unstudied, and consumption is not advised.

In Northern Asia and Europe, fly agaric grows under trees near the winter solstice and is collected for ritual use tied to the season. Its characteristic shape and coloring are still ubiquitous in many European fairy tale illustrations and Christmas traditions. It is highly toxic.

As its common name indicates, dung-loving deconica(Deconica coprophila) is most commonly found sprouting from decaying clumps of bovine or horse dung, particularly after periods of heavy rain. Perhaps unsurprisingly, there is little information available regarding its edibility. Consumption is therefore not recommended.

Oyster mushrooms grow wild but are also cultivated for sale in supermarkets. They can even be cultivated at home. They will grow on coffee grounds and spent grain, and are occasionally even fashioned into an environmentally-friendly substitute for styrofoam. There are several toxic look-alike species, so it is best to buy these mushrooms at the store.
