Christiaan Hendrik Persoon was a mycologist who made additions to Linnaeus' mushroom taxonomy.
The genus Amanita contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-amanitin.
Petter Adolf Karsten was a Finnish mycologist, the foremost expert on the fungi of Finland in his day, and known in consequence as the "father of Finnish mycology".
Ganoderma is a genus of polypore fungi in the family Ganodermataceae that includes about 80 species, many from tropical regions. Because of their genetic diversity, use in traditional Asian medicines, and potential in bioremediation, they are an important genus economically. Ganoderma can be differentiated from other polypores because they have a double-walled basidiospore. They are sometimes called shelf mushrooms or bracket fungi.
Phanerochaete is a genus of crust fungi in the family Phanerochaetaceae.
Cortinarius caperatus, commonly known as the gypsy mushroom, is an edible mushroom of the genus Cortinarius found in northern regions of Europe and North America. It was known as Rozites caperata for many years before genetic studies revealed that it belonged to the genus Cortinarius. The fruit bodies appear in autumn in coniferous and beech woods as well as heathlands in late summer and autumn. The ochre-coloured cap is up to 10 cm across and has a fibrous surface. The clay-colored gills are attached to the stipe under the cap, and the stipe is whitish with a whitish ring. The flesh has a mild smell and flavor.
Peniophora is a genus of fungi which are plant pathogens. Members of the genus belong to the class Agaricomycetes, order Russulales, and family Peniophoraceae. The genus is widespread, and contains 62 species. The species of Peniophora are resupinate, or crust-like, and are described as corticioid. A number of its members are parasitised by other fungi. For example, Tremella mesenterica is a parasite to several species of Peniophora.
Coprinellus deliquescens is a species of mushroom in the Psathyrellaceae family. It was first described as Agaricus deliquescens in 1790 by French mycologist Bulliard before being transferred to the genus Coprinellus in 1879 by Petter Karsten.
Coprinellus congregatus is a species of mushroom in the Psathyrellaceae family. It was first described in 1782 as Agaricus congregatus by French mycologist Jean Baptiste François Pierre Bulliard, and later transferred to the genus Coprinellus in 1879 by Petter Karsten. They are found in North America and Europe.
Helvella solitaria is a species of fungus in the family Helvellaceae. Originally described as Peziza solitaria by Petter Karsten in 1869, he transferred it to the genus Helvella in 1871. The fungus has a boreal and temperate distribution.
Ripartites is a genus of fungi in the Tricholomataceae family. The genus has a widespread distribution and contains five species. Species in Ripartites have small, round to subglobose spores which are yellowish-brown and ornamented. Macroscopically, they resemble Clitocybe. Ripartites was circumscribed by Petter Karsten in 1879.
Hapalopilus is a genus of poroid fungi in the family Polyporaceae. The genus is widely distributed. The generic name combines the Ancient Greek words ἁπαλός ("tender") and πιλος ("cap"). Hapalopilus was circumscribed by Finnish mycologist Petter Adolf Karsten in 1881.
Lacunoides is a genus of sea snails, marine gastropod mollusks in the family Neomphalidae.
Podostroma is a genus of fungi in the family Hypocreaceae. It was circumscribed by the Finnish mycologist Petter Karsten in 1892. The genus contains 11 species that collectively have a widespread distribution.
Argopatagus vitreus is a species of sea urchin of the family Macropneustidae. Their armour is covered with spines. It is placed in the genus Argopatagus and lives in the sea. Argopatagus vitreus was first scientifically described in 1879 by Alexander Emanuel Agassiz, an American scientist.
Strobilurus tenacellus, commonly known as the pinecone cap, is a species of agaric fungus in the family Physalacriaceae. It is found in Asia and Europe, where it grows on the fallen cones of pine and spruce trees. The fruit bodies (mushrooms) are small, with convex to flat, reddish to brownish caps up to 15 mm (0.6 in) in diameter, set atop thin cylindrical stems up to 4–7.5 cm (1.6–3.0 in) long with a rooting base. A characteristic microscopic feature of the mushroom is the sharp, thin-walled cystidia found on the stipe, gills, and cap. The mushrooms, sometimes described as edible, are too small to be of culinary interest. The fungus releases compounds called strobilurins that suppress the growth and development of other fungi. Derivatives of these compounds are used as an important class of agricultural fungicides.
Geoglossum is a genus of fungi in the family Geoglossaceae. They are commonly called earth tongues. The type species is Geoglossum glabrum. Geoglossum species are distinguished from the related genus Trichoglossum by the lack of setae on the spore bearing surface. Geoglossum species are characterized by dark, club-shaped, terrestrial ascocarps with a fertile hymenium continuing downward from the apex of the ascocarp along the stipe, eventually intergrading with a sterile stipe. The ascospores of Geoglossum range from translucent to dark brown, and are fusiform, and multiseptate. Identification of species is based on the gross morphology of the ascocarp, color and septation of the ascospores, and shape and ornamentation of the paraphyses.
Rhodonia is a fungal genus in the family Fomitopsidaceae. It is a monotypic genus, containing the single crust fungus Rhodonia placenta. A brown rot species, R. placenta is found in China, Europe, and North America, where it grows on decaying conifer wood.
Bjerkandera fumosa is a species of poroid fungus in the family Meruliaceae.
