Fungi named in 1817

Alternaria is a genus of fungi that are found worldwide. Alternaria species are known as major plant pathogens. They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma. They are present in the human mycobiome and readily cause opportunistic infections in immunocompromised people such as AIDS patients. There were about 600 known species in the genus in 2023 (although in 2008 the Dictionary of Fungi only listed 299). They are ubiquitous in the environment and are a natural part of funga almost everywhere. They

Rhizopogon is a genus of ectomycorrhizal basidiomycetes in the family Rhizopogonaceae. Species form hypogeous sporocarps commonly referred to as "false truffles". The general morphological characters of Rhizopogon sporocarps are a simplex or duplex peridium surrounding a loculate gleba that lacks a columnella. Basidiospores are produced upon basidia that are borne within the fungal hymenium that coats the interior surface of gleba locules. The peridium is often adorned with thick mycelial cords, also known as rhizomorphs, that attach the sporocarp to the surrounding substrate. The scientific

Verticillium is a genus of fungi in the division Ascomycota, and are an anamorphic form of the family Plectosphaerellaceae. The genus used to include diverse groups comprising saprobes and parasites of higher plants, insects, nematodes, mollusc eggs, and other fungi, thus the genus used to have a wide-ranging group of taxa characterised by simple but ill-defined characters. The genus, currently thought to contain 51 species, may be broadly divided into three ecologically based groups - mycopathogens, entomopathogens, and plant pathogens and related saprotrophs. However, the genus has

Dacrymyces is a genus of fungi in the family Dacrymycetaceae. Species are saprotrophs and occur on dead wood. Their distribution is worldwide. Basidiocarps (fruit bodies) are ceraceous to gelatinous, often yellow to orange, and typically disc-shaped to cushion-shaped. The genus has traditionally been differentiated from other genera in the Dacrymycetaceae on the basis of basidiocarp morphology, following (in recent years) the monograph of New Zealand mycologist Robert McNabb. Molecular research, based on cladistic analysis of DNA sequences, has however shown that morphology is not a good

Rhizopogon luteolus is an ectomycorrhizal fungus used as a soil inoculant in agriculture and horticulture. It was deliberately introduced into Pinus radiata plantations in Western Australia after it was observed to improve tree growth.

Nidularia is a genus of nine species of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled bird nests. The name comes from the Latin nidus meaning nest. The related genus Mycocalia was segregated from Nidularia in 1961 based on differences in the microscopic structure of the peridium.

Chaetomium is a genus of fungi in the Chaetomiaceae family. It is a dematiaceous (dark-walled) mold normally found in soil, air, cellulose and plant debris. According to the Dictionary of the Fungi (10th edition, 2008), there are about 95 species in the widespread genus. In 1817 Gustav Kunze established the genus Chaetomium (the plume of the helmet) to classify the species C. globosum and C. elatum. No further contributions to the genus were made until 1837 when the publication of Corda described its characteristic asci in his work, Icones Fungorum Hucusque Cognitorum. In 1915, Arthur Houston

Chaetomium globosum is a well-known mesophilic member of the mold family Chaetomiaceae. It is a saprophytic fungus that primarily resides on plants, soil, straw, and dung. Endophytic C. globosum assists in cellulose decomposition of plant cells. They are found in habitats ranging from forest plants to mountain soils across various biomes. C. globosum colonies can also be found indoors and on wooden products. Chaetomium globosum are human allergens and opportunistic agents of ungual mycosis and neurological infections. However such illnesses occur at low rates.

Biatora is a genus of lichens in the family Ramalinaceae. Originally circumscribed in 1817, the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores.

Coryneum is a genus of phytopathogenic fungi having more than 100 species, of which some cause tree cankers.

Seiridium is a genus of plant pathogens in the family Sporocadaceae. Seiridium cardinale is important to gardeners and foresters as they cause the devastating Cypress canker disease on Cupressus, Thuja, and related conifers in Northern Europe, America, Australia, and New Zealand. Seiridium cardinale is from California and was introduced to Europe around the 1930s, probably from infected nursery stock. A separate introduction affected the southern hemisphere.

Lichina is a genus of lichen-forming fungi in the family Lichinaceae. The genus contains four marine species. These cyanolichens include species such as L. pygmaea or L. confinis, in which the associated cyanobiont has been assigned to the genus Rivularia. Furthermore, evidence of a high specificity of each mycobiont towards particular cyanobiont lineages in both species has been detected.

Cladobotryum is a genus of fungi in the family Hypocreaceae.

Peridermium is a genus of rust fungi in the family Cronartiaceae. The genus was circumscribed by Johann Carl Schmidt and Gustav Kunze in 1817. Species include Peridermium californicum.

Trentepohlia aurea is a species of filamentous terrestrial green alga in the family Trentepohliaceae. It grows on a variety of substrates including rocks, old walls, concrete surfaces, tree bark, rotting wood, mosses, and wet soil. The orange coloration results from carotenoid pigments in the algal cells. Trentepohlia aurea is the type species of the genus Trentepohlia. In the British Isles, it is the most widespread and abundant species of Trentepohlia. However, many records need to be reassessed, since the name has been broadly misapplied to specimens of other species, such as Trentepohlia

Arthrinium is a genus of minute disease-causing fungi which belong to the family Apiosporaceae and which are parasitic on flowering plants such as sedges. These fungi have an anamorphic life cycle stage where spores are produced asexually in structures called conidia and a teleomorphic stage where sexual spores are produced in asci. Historically the name Arthrinum represented the anamorph form and a different genus name was used for the teleomorph form; however after a decision in 2011 one name or the other has to be selected as the current name for all cases.
