Hygrophanous
The adjective hygrophanous refers to the color change of mushroom tissue (especially the pileus surface) as it loses or absorbs water, which causes the pileipellis to become more transparent when wet and opaque when dry. When identifying hygrophanous species, one needs to be careful when matching colors to photographs or descriptions, as color can change dramatically soon after picking. Genera that are characterized by hygrophanous species include ''Agrocybe'', ''Psathyrella'', ''Psilocybe'', ''Panaeolus'', and ''Galerina''.

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...

Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp (fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium (hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as ''umbonate''. An umbo is a knobby protrusion at the center of th ...

Pileipellis
The pileipellis is the uppermost layer of hyphae in the pileus of a fungal fruit body In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particu .... It covers the trama, the fleshy tissue of the fruit body. The pileipellis is more or less synonymous with the cuticle, but the cuticle generally describes this layer as a macroscopic feature, while pileipellis refers to this structure as a microscopic layer. Pileipellis type is an important character in the identification of fungi. Pileipellis types include the cutis, trichoderm, epithelium, and hymeniderm types. Types Cutis A cutis is a type of pileipellis characterized by hyphae that are repent, that is, that run parallel to the pileus surface. In an ixocutis, the hyphae are gelatinous. Trichoderm In a trichoderm, the outermost hyphae emer ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Agrocybe
''Agrocybe'' is a genus of mushrooms in the family Strophariaceae (previously placed in the Bolbitiaceae). The genus has a widespread distribution, and contains about 100 species. Distribution Mushroom cultivation began with the Romans and Greeks, who grew the small ''Agrocybe aegerita''. The Romans believed that fungi fruited when lightning struck. In Europe, toxic forms are not normally found, but ''Agrocybe molesta'' could be confused with poisonous white ''Agaricus'' species or with poisonous ''Amanita'' species. The edible southern species ''Agrocybe aegerita'' is commonly known as the Poplar mushroom, Chestnut mushroom or Velvet pioppino (Chinese: 茶樹菇). It is a white rot fungus and is a medium-sized agaric with a convex, almost flat, cap 3 to 10 cm in diameter. Underneath, it has numerous whitish radial plates adherent to the foot, later turning to a brownish-gray color, and light elliptic spores of 8-11 by 5-7 micrometres. The white fiber foot is generally cu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Psathyrella
''Psathyrella'' is a large genus of about 400 species, 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 all members are considered inedible or worthless (for eating) and so they are often overlooked. 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 ψαθυρος, ''psathuros'' 'friable'. The type species of ''Psathyrella'' is ''Psathyrella gracilis'', which is now known as ''Psathyrella corrugis''. Characteristics In order to identify the species ...

Psilocybe
''Psilocybe'' ( ) is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Most or nearly all species contain the psychedelic compounds psilocybin and psilocin. Taxonomy Taxonomic history A 2002 study of the molecular phylogeny of the agarics indicated that the genus ''Psilocybe'' as then defined was polyphyletic, falling into two distinct clades that are not directly related to each other. The blue-staining hallucinogenic species constituted one clade and the non-bluing species the other. The previous type species of the genus, ''Psilocybe '' (now Deconica montana), was in the non-bluing clade, but in 2010 the type species was changed to '' P. semilanceata'', a member of the bluing clade. A 2006 molecular phylogenetic study of the Agaricales by Matheny and colleagues, further demonstrated the separation of the bluing and non-bluing clades of ''Psilocybe'' in a larger, strongly supported phylogenetic tree of the Agaricales. ''Psilocybe'' had ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Panaeolus
''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. Characteristics These fungi are mostly dung and grassland species, some of which are quite common in Europe and North America. The gills of ''Panaeolus'' do not deliquesce as do the members of the related genera ''Coprinellus'' and ''Coprinopsis''. Members of ''Panaeolus'' can also be mistaken for ''Psathyrella'', however the latter genus is usually found growing on wood or lignin-enriched soils and has brittle stipes. The gills of these mushrooms are black or grey and have a spotty, speckled or cloudy appearance, caused by the way that the dark spores ripen together in tiny patches on the gill surface; different patches darken at different times. The spores are smooth. The closely related genus '' Panaeolina'' shares the spotted gills but they are dark brown (not black) and the spores are orna ...

Galerina
''Galerina'' is a genus of small brown-spore saprobic fungi (colloquially often ''mushrooms''), with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of ''Psilocybe''. Species are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats. ''Galerina'' means ''helmet-like''. Taxonomic definition The genus ''Galerina'' is defined as small mushrooms of mycenoid stature, that is, roughly similar in form to ''Mycena'' species: a small conical to bell-shaped cap, and gills attached to a long and slender cartilaginous stem. Species have a pileipellis that is a cutis, and ornamented spores that are brown in deposit, where the spore ornamentation comes from an extra spore covering. Description ' ...

Psathyrella Gracilis
''Psathyrella corrugis'', is the type species of the basidiomycete fungus genus ''Psathyrella'' and family Psathyrellaceae. Originally described from Europe as ''Agaricus corrugis'', the species is considered non-toxic but lacking in flesh, flavor and texture. It is inedible. Nomenclature The lectotype of ''Psathyrella'' is ''Psathyrella gracilis'', however ''P. corrugis'' was published in 1794, 27 years before ''P. gracilis'' was first published, making ''P. corrugis'' the correct name. The name given here is according to Index Fungorum. Description The cap is 1–4 cm wide, bell-shaped and translucent when young; it flattens and becomes opaque with age. The gills are slightly reddish. The whitish stalk is tall and 1–3 mm wide. The spores are purple-brown, elliptical, and smooth. It can be found growing around areas of dead wood. The species sometimes fruits with ''Tubaria furfuracea''. A similar species is ''Psathyrella candolleana ''Candolleomyces candolleanus'' (forme ...

Panaeolina Foenisecii
''Panaeolus foenisecii'', commonly called the mower's mushroom, haymaker or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns and is not an edible mushroom. In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-HTP and 5-hydroxyindoleacetic acid. In many field guides it is listed as psychoactive; however, the mushroom does not produce any hallucinogenic effects. Description *Cap: 1 to 3 cm across, conic to convex, chestnut brown to tan, hygrophanous, often with a dark band around the margin which fades as the mushroom dries. *Gills: Broad, adnate, brown with lighter edges, becoming mottled as the spores mature. *Stipe: 3 to 8 cm by 1 to 3 mm, fragile, hollow, beige to light brown, fibrous, pruinose, and slightly striate. *Taste: A slightly unpleasant nutty fungal taste. *Odor: Nutty, slightly unpleasant. *Spore print: Dark walnut brown. *Microscopic features: Spores measure 12–17 x 7–11 ...
