Secotioid Fungi
Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and 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 and truffles, of which the ...

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 secotio ...

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. 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. Fruit bodies appear similar to unopened mushrooms, measuring tall with diameter caps that are whitish to brownish. They have a short but distinct whitish stipe that extend through the internal spore mass (gleba) of the fruit body into the cap. The gleba consists of irregular chambers made of contorted 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 ring on the stipe. Taxonomy The species was first described in 1899 by American mycologist Harvey Willson Harkness as ''Secotium nubigenum''. Har ...

Hypogeous
Hypogeal, hypogean, hypogeic and hypogeous (; ) are biological terms describing an organism's activity below the soil surface. In botany, a seed is described as showing hypogeal germination when the cotyledons of the germinating seed remain non-photosynthetic, inside the seed shell, and below ground.{{cite book, author1=Adrian D. Bell, author2=Alan Bryan, title=Plant Form: An Illustrated Guide to Flowering Plant Morphology, url=https://books.google.com/books?id=SM3khPHXhKEC&pg=PA200, year=2008, publisher=Timber Press, isbn=978-0-88192-850-1, page=200 The converse, where the cotyledons expand, throw off the seed shell and become photosynthetic above the ground, is epigeal germination. In water purification works, the hypogeal (or Schmutzdecke) layer is a biological film just below the surface of slow sand filters. It contains microorganisms that remove bacteria and trap contaminant particles. The terms hypogean and hypogeic are used for fossorial (burrowing) and troglobitic (or ...

Epigeous
Epigeal, epigean, epigeic and epigeous are biological terms describing an organism's activity above the soil surface. In botany, a seed is described as showing epigeal germination when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The opposite kind, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal germination. The terms epigean, epigeic or epigeous are used for organisms that crawl (epigean), creep like a vine (epigeal), or grow (epigeous) on the soil surface: they are also used more generally for animals that neither burrow nor swim nor fly. The opposite terms are hypogean, hypogeic and hypogeous. An epigeal nest is a term used for a termite mound, the above ground nest of a colony of termites.

Gleba
Gleba (, from Latin ''glaeba, glēba'', "lump") is the fleshy spore-bearing inner mass of certain fungi such as the puffball or stinkhorn. The gleba is a solid mass of spores, generated within an enclosed area within the sporocarp. The continuous maturity of the sporogenous cells leave the spores behind as a powdery mass that can be easily blown away. The gleba may be sticky or it may be enclosed in a case (peridiole). It is a tissue usually found in an angiocarpous fruit-body, especially gasteromycetes. Angiocarpous fruit-bodies usually consist of fruit enclosed within a covering that does not form a part of itself; such as the filbert covered by its husk, or the acorn seated in its cupule. The presence of gleba can be found in earthballs and puffballs. The gleba consists of mycelium, and basidia and may also contain capillitium threads. Gleba found on the fruit body of species in the family Phallaceae is typically gelatinous, often fetid-smelling, and deliquescent (becomin ...

Hydnangiaceae
The Hydnangiaceae are a family of fungi in the mushroom 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 fruit bodies with stipes and caps (pileate-stipiate), or 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 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 present, the hymenia are not gelatinized, and are formed in locules. Basidia are club-shaped (clavate), with two or four ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laccaria Laccata
''Laccaria laccata'', commonly known as the deceiver, or waxy laccaria, is a white-spored species of small edible mushroom found throughout North America and Europe. It is a 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. The species is often considered by mushroom collectors to be a 'mushroom weed' because of its abundance and plain stature. 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 of the cosmopolitan mushroom genus ''Laccaria'' ...

Cortinarius
''Cortinarius'' is a globally distributed genus of mushrooms in the family Cortinariaceae. It is suspected to be the largest genus of agarics, containing over 2,000 widespread species. A common feature among all species in the genus ''Cortinarius'' is that young specimens have a cortina (veil) between the cap and the stem, hence the name, meaning ''curtained''. Most of the fibres of the cortina are ephemeral and will leave no trace once gone, except for limited remnants on the stem or cap edge in some species. All have a rusty brown spore print. The common names cortinar and webcap refer to members of the genus. Due to dangerous toxicity of several species (such as ''Cortinarius orellanus'') and the fact that it is difficult to distinguish between various species of the genus, non-expert consumption of mushrooms from the genus is discouraged. Distinguishing features The veil protects the gills in younger specimens and usually disappears leaving little to no trace of itself as the ...

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) *'' Galera'' (4 species) *''Galerina'' (307 species) *'' Galerula'' (3 species) *''Gymnopilus'' (209 species) *''Hebeloma'' (355 species) *'' Hymenogaster'' (79 species) *'' Naematoloma' ...

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] |
