Secotioid
Secotioid fungi produce an intermediate fruiting body form that is between the mushroom-like hymenomycetes and the closed bag-shaped gasteroid fungi, gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropism, geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed (e.g. gills completely inclosed and never exposed as in the secotioid form of ''Lentinus tigrinus'')—note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory. Explanation of secotioid development and gasteromycetation Historically agarics and boletes (which bear their spores on a hymenium of gills or tubes respectively) were classified quite separately from the gasteroid fungi, such as puff-balls ...

Weraroa Novae Zelandiae
''Weraroa'' was a genus of mushrooms from the families Hymenogastraceae and Strophariaceae. The genus was initially described by mycologist Rolf Singer in 1958 to accommodate the single species ''Secotium novae-zelandiae'' reported by Gordon Herriott Cunningham in 1924.Cunningham GH. (1924). "A critical revision of the Australian and New Zealand species of the genus ''Secotium''". ''Proceedings of the Linnean Society of New South Wales'' 49(2): 97–119. It was thought that the genus represented an intermediary evolutionary stage between a wikt:hypogeous, hypogeous (underground) ancestor and the related wikt:epigeous, epigeous (above ground) genus ''Stropharia''. Advances in phylogenetics and taxonomy, taxonomic changes since 1958 found it contained unrelated species from multiple genera. It is now considered a synonym of the genus ''Psilocybe''. Description The following descriptions may not represent all species formerly the genus. Macroscopic ''Weraroa'' contained secoti ...

Secotium
''Secotium'' is a genus of fungi in the family Agaricaceae. The members of this genus are closely related to ordinary ''Agaricus'' mushrooms, but do not open out in the usual way; this has given rise to the term "secotioid" for such mushrooms in general. They are thought to form an evolutionary link between agarics and gasteroid fungi (whose spores are enclosed in a pouch-like structure). ''Secotium'' is a widespread genus, with species that are predominantly found in warm and arid regions. Species The secotioid species '' Agaricus deserticola'' used to be named ''Secotium texense'' before its strong connection to ''Agaricus'' caused it to be reclassified.

Puff-balls
Puffballs are a type of fungus featuring a ball-shaped fruit body that (when mature) bursts on contact or impact, releasing a cloud of dust-like spores into the surrounding area. Puffballs belong to the division Basidiomycota and encompass several genera, including ''Calvatia'', ''Calbovista'' and ''Lycoperdon''. The puffballs were previously treated as a taxonomic group called the Gasteromycetes or Gasteromycetidae, but they are now known to be a polyphyletic assemblage. The distinguishing feature of all puffballs is that they do not have an open cap with spore-bearing gills. Instead, spores are produced internally, in a spheroidal fruit body called a ''gasterothecium'' (gasteroid 'stomach-like' basidiocarp). As the spores mature, they form a mass called a gleba in the centre of the fruitbody that is often of a distinctive color and texture. The basidiocarp remains closed until after the spores have been released from the basidia. Eventually, it develops an aperture, or dries, b ...

Gasteroid Fungi
The gasteroid fungi are a group of fungi in the Basidiomycota. Species were formerly placed in the obsolete class Gasteromycetes Fr. (literally "stomach fungi"), or the equally obsolete order Gasteromycetales Rea, because they produce spores inside their basidiocarps (fruit bodies) rather than on an outer surface. However, the class is polyphyletic, as such species—which include puffballs, earthballs, earthstars, stinkhorns, bird's nest fungi, and false truffles—are not closely related to each other. Because they are often studied as a group, it has been convenient to retain the informal (non-taxonomic) name of "gasteroid fungi". History Several gasteroid fungi—such as the stinkhorn, ''Phallus impudicus'' L.—were formally described by Carl Linnaeus in his original ''Species Plantarum'' of 1753, but the first critical treatment of the group was by Christiaan Hendrik Persoon in his ''Synopsis methodica fungorum'' of 1801. Until 1981, this book was the start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pholiota Nubigena
''Pholiota nubigena'', commonly known as the gastroid pholiota or the bubble gum fungus, is a species of secotioid fungus in the family Strophariaceae. The fruit bodies appear similar to unopened mushrooms, measuring tall with diameter pileus (mycology), caps that are whitish to brownish. They have a short but distinct whitish stipe (mycology), stipe that extend through the internal spore mass (gleba) of the fruit body into the cap. The gleba consists of irregular locule, chambers made of contorted lamella (mycology), gills that are brownish in color. A whitish, cottony partial veil is present in young specimens, but it often disappears in age and does not leave a annulus (mycology), ring on the stipe. It is found in mountainous areas of the western United States, where it grows on rotting conifer wood, often fir logs. It fruits in spring, often under snow, and early summer toward the end of the snowmelt period in high mountain forests. Taxonomy The species was first species ...

Strophariaceae
The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith. Genera * The genus ''Stropharia'' mainly consists of medium to large agarics with a distinct membranous annulus. Spore-print color is generally medium to dark purple-brown, except for a few species with rusty-brown spores. There is a great deal of variation, however, since this group, as presently delimited, is polyphyletic. Members of the core clade of ''Stropharia'' are characterized by crystalline acanthocytes among the hyphae t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortinariaceae
The Cortinariaceae are a large family of gilled mushrooms found worldwide, containing over 3200 species. The family takes its name from its largest genus, the varied species of the genus ''Cortinarius''. Many genera formerly in the Cortinariaceae have been placed in various other families, including Hymenogastraceae, Inocybaceae and Bolbitiaceae. The deadly toxin orellanine has been found in at least 34 Cortinariaceae. Taxonomy Cortinariaceae is a family of mushrooms within the Order Agaricales. The spore producing hymenium is located on the gills. The pileipellis is a cutis. The spores are brown in deposit and, in most genera in this family, the spores are ornamented. In 2022 the family Cortinariaceae, which previously contained only the one genus of ''Cortinarius'' was reclassified based on genomic data and split into the genera of ''Cortinarius'', '' Aureonarius'', '' Austrocortinarius'', '' Calonarius'', '' Cystinarius'', '' Hygronarius'', '' Mystinarius'', '' Phlegmacium'' ...

Hymenogastraceae
The Hymenogastraceae is a family of fungi in the order Agaricales with both agaric and false-truffle shaped fruitbodies. Formerly, prior to molecular analyses, the family was restricted to the false-truffle genera. The mushroom genus '' Psilocybe'' in the ''Hymenogastraceae'' is now restricted to the hallucinogenic species while nonhallucinogenic former species are largely in the genus '' Deconica'' classified in the Strophariaceae. One of the two known species of '' Wakefieldia'' has been found recently to belong to this family but formal transfer cannot be made until the phylogeny of the type species of the genus is resolved. '' Psathyloma'', added to the family in 2016, was circumscribed to contain two agarics found in New Zealand. Genera *'' Alnicola'' (12 species) *'' Dendrogaster'' (1 species) *'' Flammula'' (113 species) *'' Galera'' (4 species) *'' Galerina'' (307 species) *'' Galerula'' (3 species) *'' Gymnopilus'' (209 species) *''Hebeloma ''Hebeloma'' is a genu ...

Hydnangiaceae
The Hydnangiaceae are a family (biology), family of fungi in the mushroom order (biology), order Agaricales. Widespread in temperate and tropical regions throughout the world, the family contains about 30 species in four genera. Species in the Hydnangiaceae form ectomycorrhizal relationships with various species of trees in both coniferous and deciduous forests. Description They may have basidiocarp, fruit bodies with stipe (mycology), stipes and pileus (mycology), caps (pileate-stipiate), or gasteroid fungi, gasteroid (with internal spore production, like puffballs). When pileate, the cap is smooth to scaly, sometimes striate, typically orange-brown or violet in color. The lamella (mycology), gills are widely spaced, thick, and waxy. In gasteroid forms, fruit body shape is irregular, with thin walls. Also, the peridium (the outer layer of the spore-bearing organ) is sometimes short-lasting (evanescent). Columella (the central, sterile part of the sporangium) may be absent or pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortinarius
''Cortinarius'' is a globally distributed genus of fungus in the family Cortinariaceae. Its members are commonly known by the names cortinar and webcap. It is suspected to be the largest genus of agarics, containing over 2,000 widespread species. Young specimens have a cortina (veil) between the cap and the stem, hence the name. Most of the fibres of the cortina are ephemeral and leave no more than limited remnants on the stem or cap edge. All species have a rusty brown spore print. Several species (such as ''Cortinarius orellanus, C. orellanus'') are highly Mushroom poisoning, toxic and many species are difficult to distinguish, making their consumption inadvisable. Taxonomy Molecular phylogenetics, Molecular studies of members of the genus ''Rozites'', including its most famous member ''R. caperata'', have shown them nested within ''Cortinarius'' and have been sunk into this genus. This genus was erected on the basis of a double veil, yet its members do not form a di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laccaria Laccata
''Laccaria laccata'', commonly known as the deceiver, lackluster laccaria, or waxy laccaria, is a species of fungus. It is a small but highly variable mushroom (hence 'deceiver'), and can look quite washed out, colorless and drab, but when younger it often assumes red, pinkish brown, and orange tones. It has white spores. Found throughout North America and Europe, the species is often considered by mushroom collectors to be a 'mushroom weed' because of its abundance and plain stature. The cap is edible. Taxonomy The deceiver was first described by Tyrolian naturalist Giovanni Antonio Scopoli in 1772 as ''Agaricus laccatus'', before being given its current binomial name by Mordecai Cubitt Cooke in 1884. The specific epithet is derived from the Latin adjective ''laccatus'' 'varnished' or 'shining'. ''Clitocybe laccata'' is an old alternative name. Var. ''pallidifolia'', described by Charles Horton Peck, is the most common variety found in North America. It is the type species o ...
