Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped 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 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 —note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory.
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus.
Cortinarius rubellus, commonly known as the deadly webcap, is a species of fungus in the family Cortinariaceae, native to high-latitude temperate to subalpine forests of Eurasia and North America. Within the genus it belongs to a group known as the Orellani, all of which are highly toxic. Eating them results in kidney failure, which is often irreversible. The mushroom is generally tan to brown all over, with a conical to convex cap 2.5 to 8 centimetres in diameter, adnate gills and a 5.5 to 11 cm tall stipe.
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 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.
Phlegmacium ponderosum, also known as the Ponderous Cortinarius, is a species of mushroom producing fungus in the family Cortinariaceae. It is very large and due to its thick stem it can be mistaken for Boletus edulis.
Cortinarius mucosus, commonly known as the orange webcap or the slimy cortinarius, is a species of mushroom in the family Cortinariaceae. In North America, the species is more commonly associated with northern coniferous forests. The specific epithet is derived from the Latin word mucosus, meaning mucus.
Phlegmacium triumphans, also known as the birch webcap, or yellow girdled webcap is a basidiomycete mushroom in the family Cortinariaceae. It is found in Europe and regarded as edible by some authorities, although others call it suspect and it resembles inedible species.
The Orellani are a group of seven related species in the genus Cortinarius that have been classified as a section of the subgenus Leprocybe or a subgenus in their own right. They are among world's most poisonous mushrooms as they contain the highly toxic compound orellanine. The best-known species are the deadly webcap and the fool's webcap, C. orellanus.
Cortinarius orellanus, commonly known as the fool's webcap or fools webcap, is a species of deadly fungus in the family Cortinariaceae native to Europe. Within the genus it belongs to a group known as the Orellani, all of which are highly toxic—eating them results in kidney failure, which is often irreversible. The mushroom is generally tan to brown all over.
Austrocortinarius australiensis, commonly known as the skirt webcap, is a species of mushroom in the family Cortinariaceae which is native to Australia and New Zealand. The white mushrooms appear in autumn and can grow very large, with their caps reaching 30 cm (12 in) in diameter.
Phlegmacium flavivelatum is a species of fungus in the family Cortinariaceae.
Phlegmacium kytoevuorii is a species of fungus in the family Cortinariaceae.
Calonarius luteicolor is a species of fungus in the family Cortinariaceae.
Phlegmacium myrtilliphilum is a species of fungus in the family Cortinariaceae.
Phlegmacium subrubrovelatum is a species of mushroom producing fungus in the family Cortinariaceae. It was previously known as Cortinarius subrubrovelatus.
Thaxterogaster talimultiformis is a species of mushroom producing fungus in the family Cortinariaceae. It was previously known as Cortinarius talimultiformis.
Phlegmacium boreicyanites is a species of fungus in the family Cortinariaceae
Phlegmacium boreidionysae is a species of fungus in the family Cortinariaceae.
Thaxterogaster caesiophylloides is a species of fungus in family Cortinariaceae.
Phlegmacium glaucopus is a species of fungus in the family Cortinariaceae. It is commonly known as the blue-foot webcap.
