Psathyrella Globosivelata
''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 it ...

Psathyrella Corrugis
''Psathyrella corrugis'', is the type species of the basidiomycete fungus genus ''Psathyrella'' and family Psathyrellaceae. It is common in North America and is regarded as inedible. Taxonomy It was originally described from Europe as ''Agaricus corrugis''. The lectotype of ''Psathyrella'' is ''P. gracilis'', but naming priority is given to ''P. corrugis'', published in 1794 (27 years earlier than ''P. gracilis''). Description The cap is 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. The spore print is dark brown to black, sometimes with hints of purple. The species is considered non-toxic but lacking in flesh, flavor and texture. It is inedible. Similar species A similar species is ''Candolleomyces candolleanus''. Microscopy may be needed to distinguish ''P. corrugis'' from simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 The pileipellis is the uppermost layer of hyphae in the pileus of a fungal fruit body. 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 ... 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''.

Psathyrellaceae
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. ...

Psathyrella Piluliformis
''Psathyrella piluliformis'' is a species of agaric fungus in the family Psathyrellaceae. Description It produces fruit bodies (mushrooms) with broadly convex caps measuring in diameter. The caps are chestnut to reddish brown, the color fading with age and with dry weather. Fragments of the partial veil may remain on the cap margin, and as a wispy band of hairs on the stipe. The closely spaced gills have an adnate attachment to the stipe. They are initially tan until the spores mature, when the gills turn dark brown. The stipe is 2–7 cm tall and 3–7 mm wide, white, smooth, hollow, and bulging at the base. The spore print is dark brown, sometimes purplish. Similar species Similar species include ''Psathyrella carbonicola'', '' P. longipes'', ''P. longistriata'', ''P. multipedata'', '' P. spadicea'', and '' Parasola conopilus''.

Psathyrella Candolleana
''Candolleomyces candolleanus'' (formerly known as ''Psathyrella candolleana'') is a species of fungus in the family Psathyrellaceae. The color is tannish when young, fading to white. It is found in lawns in North America. Description The cap is tan when young, fading to whitish, and growing to in diameter; they are initially conical, later becoming rounded and finally with upturned margins in maturity. The cap margin is irregular and radially asymmetrical—a defining characteristic of this species. It can retain veil fragments on the edge and center. The white stalk is tall and 3–7 mm wide. The spore print is purple-brown, while spores are smooth and elliptical, measuring 6.5–8 by 4–5 μm. Similar species One similar species is '' Psathyrella gracilis''. Some species may have darker caps when young, drying to match that of ''C. candolleanus''. Also similar are '' C. tuberculatus'', '' Britzelmayria multipedata'', and members of '' Coprinopsis ...

Psathyrella Ammophila
''Psathyrella ammophila'' is a species of fungus in the family Psathyrellaceae and is found throughout Europe. Commonly known as the dune brittlestem, this agaric primarily grows on sand dunes near marram grass, feeding saprotrophically on the decaying roots. The season of growth is generally May to November. ''P. ammophila'' is variable in appearance, changing colour and shape during its lifespan. Initially bell-shaped and tan or pale brown, the cap gradually flattens and darkens, becoming dark brown with a depressed shape as it ages. Taxonomy ''Psathyrella ammophila'' was first described in 1868 by Michel Charles Durieu de Maisonneuve and Joseph-Henri Léveillé in one of Durieu de Maisonneuve's publications on the flora, fauna, and funga of Algeria, ''Exploration scientifique de l'Algérie: Sciences naturelles, botanique''. They gave it the scientific name ''Agaricus ammophilus''. The species was identified and described a further five times under different names, ...

List Of Psathyrella Species
This is a list of ''Psathyrella'' species. Many of its members were formerly classified in the genera ''Hypholoma'', ''Psilocybe'', and ''Stropharia''. Also some well-known species have been moved to new genera, for instance ''Psathyrella'' ''spadicea'' is now ''Homophron spadiceum''. ''Lacrymaria lacrymabunda'' has often been classified as a ''Psathyrella''. According to one 2008 estimate, the genus contains about 400 species. In 2020 many members of the family Psathyrellaceae were reclassified by the German mycologists Dieter Wächter & Andreas Melzer (Mycologist), Andreas Melzer based on Phylogenetics, phylogenetic analysis. This study created the new genera Britzelmayria, Candolleomyces and Olotia and placed numerous former ''Psathyrella'' species within them. Notable changes include ''Psathyrella candolleana'' being reclassified as ''Candolleomyces candolleanus'' and ''Psathyrella multipedata'' being reclassified as ''Britzelmayria multipedata.''

Caulocystidium
A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or with a hand lens. ...
