Agaricaceae

(Family)

Overview

[ Back to top ]

The Agaricaceae is a family of fungi and includes organisms previously known as Tulostomataceae and Lepiotaceae.

Genera Leucoagaricus and Leucocoprinus are varieties of fungus cultivated by ants in ant-fungus mutualism.

The Family Agaricaceae is further organized into finer groupings including:

Genera

[ Back to top ]

Agaricus

(Gr. agarikon: agaric, a kind of mushroom) A genus of the phylum Basidiomycota. [more]

Allopsalliota

[more]

Amanita

The Amanita contains about 600 species of agarics including some of the most toxic known mushrooms found worldwide. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is alpha-amanitin. [more]

Chlorophyllum

The genus Chlorophyllum is a small genus of large agarics similar in appearance to the true . The best known members are the edible shaggy parasol, a name applied to two very similar species Chlorophyllum rhacodes and C. brunneum, and the poisonous C. molybdites, a fungus widespread in subtropical regions around the world.

Coprinopsis

The Psathyrellaceae is a family of dark-spored that generally have rather soft, fragile fruiting bodies, and are characterized by black or dark brown, rarely reddish, or even pastel colored spore prints. About 50% of the species produce fruiting bodies that dissolve into ink-like ooze when the spores are mature via self digestion (autodigestion). Prior to phylogenetic research based upon DNA comparisons, most of the species that autodigested were previously classified in another family called the Coprinaceae that contained all of the inky cap mushrooms. The reclassification took place because the type species of Coprinus, Coprinus comatus, and a few other species were found to belong to another family, the Agaricaceae. The former group of old Coprinus was split between two families, and the name "Coprinaceae" became a synonym of the Agaricaceae in its 21st century phylogenetic redefinition. Note that in the 1800s and early 1900s the family name Agaricaceae had far broader application, while in the late 1900s it had a narrower application. Ironically, the family name Psathyrellaceae is based upon the subfamily name Psathyrelloideae, that had been classified in the Coprinaceae. The type genus, Psathyrella consists of species that produce fruitbodies do not liquify via autodigestion. Currently Psathyrella is a polyphyletic genus that will be further fragmented and reclassified. Lacrymaria is another genus that does not autodigest its fruitbodies. It is characterized by rough basidiospores and lamellar edges that exude beads of clear liquid when in prime condition, hence the Latin reference, 'lacrym-" to crying (tears). [more]

Coprinus

The genus Coprinus is a small genus of consisting of Coprinus comatus (the shaggy mane) and several of its close relatives. Until 2001, Coprinus was a large genus consisting of all agaric species in which the lamellae autodigested to release their spores. (The black ink-like liquid this would create gave these species their common name "inky cap".) Molecular phylogenetic investigation found that Coprinus comatus was only a distant relative of the other members of Coprinus, and was closer to genera in the Agaricaceae. Since Coprinus comatus is the type species of Coprinus, only that species and its close relatives C. sterquilinus and C. spadiceisporus retained the name of the genus. [more]

Lepiota

Lepiota is a of gilled mushrooms, in the order Agaricales. Though they have white spores, they are related to the familiar brown spored mushrooms of the genus Agaricus. They typically have rings on the stems, which in larger species are detachable and glide up and down the stem. The cap usually has scales: the colors of the cap, gills and scales are important in determining the exact species, as is sometimes the smell. [more]
