Fungi named in 1790

Peziza vesiculosa, commonly known as the common dung cup, is a species of apothecial fungus belonging to the family Pezizaceae.

Clavaria fragilis, commonly known as fairy fingers, white worm coral, or white spindles, is a species of fungus in the family Clavariaceae. It is synonymous with Clavaria vermicularis. The fungus is the type species of the genus Clavaria and is a typical member of the clavarioid or club fungi. It produces tubular, unbranched, white basidiocarps (fruit bodies) that typically grow in clusters. The fruit bodies can reach dimensions of 15 cm (6 in) tall by 0.5 cm (1⁄4 in) thick. There are several similar coral-like fungi. Clavaria fragilis is a saprobic species, growing in woodland litter or in

Cladonia furcata or the many-forked cup lichen is a species of cup lichen in the family Cladoniaceae. It has an intermediate to tolerant air pollution sensitivity. Extracts of this species have been shown to kill leukemia cells in vitro, and may have possible value in the treatment of cancer.

Fistulina is a genus of fungi in the family Fistulinaceae. Species in the genus cause a brown rot of both dead and living hardwood trees.

Cladonia digitata, commonly known as the finger cup lichen, is a cup lichen species in the family Cladoniaceae.

Tympanis is a genus of fungi in the family Helotiaceae. The genus contains 29 species.

Sphaerobolus is a genus of fungi in the family Geastraceae. Commonly known as the "shotgun fungus", "artillery fungus" or "cannonball fungus", species discharge their spores with explosive force. Discharged spore sacs are sticky and have a tendency to strongly adhere to whatever surface they encounter, making them a nuisance to homeowners, pressure washing contractors, landscape mulch producers and insurance companies.

Peltigera horizontalis is a species of lichen in the family Peltigeraceae. It was first described by British botanist William Hudson in 1762 as Lichen horizontalis. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Peltigera in 1790.

Umbilicaria deusta, commonly known as peppered rock tripe, is a widely distributed species of saxicolous lichen in the family Umbilicariaceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen polyphyllus. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Umbilicaria in 1790. The lichen has a dark brown to nearly black thallus that typically measures 1–5 cm (0.4–2.0 in) in diameter. The upper surface is covered with tiny black dots that are granular isidia; the lower surface is the same colour as the upper surface, and is either

Cladonia cornuta or the bighorn cup lichen is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described as a new species by Swedish lichenologist Carl Linnaeus in his seminal 1753 work Species Plantarum. German biologist Georg Franz Hoffmann transferred it to the genus Cladonia in 1791. The lichen has a distribution that is circumpolar, boreal, and arctic. It has also been recorded from the Southern Hemisphere. In North America, Cladonia cornuta is colloquially known as the bighorn Cladonia.

Umbilicaria polyphylla, commonly known as petaled rock tripe, is a widely distributed species of saxicolous lichen in the family Umbilicariaceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen polyphyllus. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Umbilicaria in 1790. The lichen has a dark brown to black thallus that measures 2–6 cm (0.8–2.4 in) in diameter. The upper surface is smooth, while the lower surface is sooty black. It grows on exposed rocks, typically in arctic-alpine habitats. In Iceland, it has the

Thelebolus is a genus of fungi in the Thelebolaceae family. Often considered related to Pezizales, 18S phylogenies show Thelebolales are a sister group to Pseudeurotiaceae and Leotiales. ITS is an adequate DNA barcode but there are only six variable sites in Thelebolus; β-tubulin is a recommended secondary barcode. Their ascomata are < 500 ųm diam. and are usually considered apothecia. Cleistothecium-like or perithecium-like variants occur, but all have asci arranged in a hymenium. Most species have eight ellipsoidal ascospores in a club-shaped ascus, but some Thelebolus asci have hundreds of

Myrothecium is a genus of fungi in the order Hypocreales and is now placed in the family Stachybotryaceae.

Tubercularia is a genus of fungi in the family Nectriaceae. With the change to single name nomenclature in fungi, Tubercularia is now considered a synonym of Nectria.

Stilbum is a genus of fungi in the family Chionosphaeraceae. Though many species were formerly referred to the genus, it is effectively monotypic since the type species, Stilbum vulgare, currently has no close relative. Stilbum vulgare forms groups of minute, gelatinous, synnema-like basidiocarps (fruit bodies) up to 0.5 mm tall with a distinct stem and inflated, fertile head. Microscopically, it produces auricularioid (laterally septate) basidia and basidiospores that germinate by budding off yeast cells. The species has been collected on rotting wood and old agaric fruit bodies and may be a

Daedalea is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1801 by mycologist Christian Hendrik Persoon, based on the type D. quercina and four other species. The generic name is derived from the Ancient Greek δαιδαλεος ("curiously wrought").

Ramaria gelatinosa, commonly known as the gelatinous coral, is a coral mushroom in the family Gomphaceae. It is found in Europe and North America. The species was first described by Theodor Holmskjold in 1790. The oregonensis variety, only reported from the Pacific Northwest, has translucent and gelatinous flesh and a yellow band on the top part of the stem. It can be found growing around fallen wood. It differs microscopically from var. gelatinosa. It is reportedly inedible, as are most gelatinous species of the genus for most people, and may be poisonous. Similar species including R.

Atractobolus is a genus of fungi in the Ascomycota phylum. The relationship of this taxon to other taxa within the phylum is unknown (incertae sedis), and it has not yet been placed with certainty into any class, order, or family.
