Given the question: Information:  - Psathyrella is a large genus of about 400 fungi , and is similar to the genera Coprinellus , Coprinopsis , Coprinus and Panaeolus , usually with a thin cap and white or yellowish white hollow stem . The caps do not self digest as do those of Coprinellus and Coprinopsis . Some also have brown spores rather than black . These fungi are often drab - colored , difficult to identify , and inedible , and so they are sometimes considered uninteresting . However they are quite common and can occur at times when there are few other mushrooms to be seen . The first report of a gilled mushroom fruiting underwater is Psathyrella aquatica . The genus name Psathyrella is a diminutive form of Psathyra , derived from the Greek word meaning `` friable '' , psathuros (  )  - Psathyrella aquatica is a species of fungus from Oregon, first described in the journal "Mycologia" in 2010. It represents the first ever report of a basidiomycete fruiting underwater.   - The Agaricaceae are a family of basidiomycete fungi and include the genus "Agaricus", as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.  - Coprinus comatus, the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The caps are white, and covered with scalesthis is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and secrete a black liquid filled with spores (hence the ink cap name). This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.  - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.  - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - Coprinus is a small genus of mushroom-forming fungi 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.  - Basidiomycota is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi.  - Mycologia is a peer-reviewed scientific journal that publishes papers on all aspects of the fungi, including lichens. It first appeared as a bimonthly journal in January 1909, published by the New York Botanical Garden under the editorship of William Murrill. It became the official journal of the Mycological Society of America, which still publishes it today. It was formed as a merger of the "Journal of Mycology" (14 volumes; 18851908) and the "Mycological Bulletin" (7 volumes; 1903-1908). The "Mycological Bulletin" was known as the "Ohio Mycological Bulletin" in its first volume.  - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - The Psathyrellaceae are a family of dark-spored agarics that generally have rather soft, fragile fruiting bodies, and are characterized by black, dark brown, rarely reddish, or even pastel-colored spore prints. About 50% of species produce fruiting bodies that dissolve into ink-like ooze when the spores are mature via autodigestion. Prior to phylogenetic research based upon DNA comparisons, most of the species that autodigested were classified as Coprinaceae, which contained all of the inky-cap mushrooms. However, the type species of "Coprinus", "Coprinus comatus", and a few other species, were found to be more closely related to Agaricaceae. The former genus "Coprinus" was split between two families, and the name "Coprinaceae" became a synonym of Agaricaceae in its 21st-century phylogenetic redefinition. Note that in the 19th and early 20th centuries the family name Agaricaceae had far broader application, while in the late 20th century it had a narrower application. The family name Psathyrellaceae is based on the former Coprinaceae subfamily name Psathyrelloideae. The type genus "Psathyrella" consists of species that produce fruiting bodies which do not liquify via autodigestion. "Psathyrella" remained a polyphyletic genus until it was split into several genera including 3 new ones in 2015. "Lacrymaria" is another genus that does not autodigest its fruiting bodies. It is characterized by rough basidiospores and lamellar edges that exude beads of clear liquid when in prime condition, hence the Latin reference, "lacryma" (tears).  - An agaric or is a type of mushroom fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically agaric meant 'tree-fungus' (after Latin "agaricum"); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name "Agaricus" for gilled mushrooms.  - Coprinopsis is a genus of mushrooms in the family Psathyrellaceae. "Coprinopsis" was split out of the genus "Coprinus" based on molecular data. The species "Coprinopsis cinerea" (="Coprinus cinereus") is a model organism for mushroom-forming basidiomycota, and its genome has recently been sequenced completely.  - Coprinellus is a genus of mushroom-forming fungi in the family Psathyrellaceae. The genus was circumscribed by Petter Karsten in 1879. Most "Coprinellus" species were transferred from the once large genus "Coprinus". Molecular studies published in 2001 redistributed "Coprinus" species to "Psathyrella", or the segregate genera "Coprinopsis" and "Coprinellus". , Index Fungorum accepts 62 species of "Coprinellus".  - Panaeolus is a genus of small, black-spored, saprotrophic agarics. The word "Panaeolus" is Greek for "all variegated", alluding to the spotted gills of the mushrooms produced.  - A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms such as mushrooms and bracket fungi. These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals.
