Fungi named in 1794

Morchella, the true morels, is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales (division Ascomycota). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps. Morels are prized by gourmet cooks, particularly in Catalan and French cuisine, but can be toxic if consumed raw or undercooked. Due to difficulties in cultivation, commercial harvesting of wild morels has become a multimillion-dollar industry in the temperate Northern Hemisphere, in particular North America, Turkey, China, the

Morchella esculenta (commonly known as common morel, morel, yellow morel, true morel, morel mushroom, and sponge morel) is a species of fungus in the family Morchellaceae of the Ascomycota. Each fruit body begins as a tightly compressed, grayish sponge with lighter ridges, and expands to form a large yellowish sponge with large pits and ridges raised on a large white stem. The pitted yellow-brown caps measure 2–7 centimetres (1–3 inches) broad by 2–10 cm (1–4 in) tall, and are fused to the stem at its lower margin, forming a continuous hollow. The pits are rounded and irregularly arranged.

Hericium coralloides is a saprotrophic fungus, commonly known as coral tooth fungus or comb coral mushroom.

Stem rust, also known as cereal rust, black rust, red rust or red dust, is caused by the fungus Puccinia graminis, which causes significant disease in cereal crops. Crop species that are affected by the disease include bread wheat, durum wheat, barley and triticale. These diseases have affected cereal farming throughout history. The annual recurrence of stem rust of wheat in North Indian plains was discovered by K. C. Mehta. Since the 1950s, wheat strains bred to be resistant to stem rust have become available. Fungicides effective against stem rust are available as well. In 1999 a new, more

Geastrum (orthographical variant Geaster) is a genus of puffball-like mushrooms in the family Geastraceae. Many species are commonly known as earthstars. The name, which comes from geo meaning earth and aster meaning star, refers to the behavior of the outer peridium. At maturity, the outer layer of the fruiting body splits into segments which turn outward creating a star-like pattern on the ground. The inner peridium is called a spore sac. In some species, the outer peridium splits from a middle layer, causing the spore sac to arch off the ground. If the outer peridium opens when wet and

Trichoderma is a genus of fungi in the family Hypocreaceae that is present in all soils, where they are the most prevalent culturable fungi. Many species in this genus can be characterized as opportunistic avirulent plant symbionts. This refers to the ability of several Trichoderma species to form mutualistic endophytic relationships with several plant species. Trichoderma species are also responsible for green mold disease in mushroom cultivation. The genomes of several Trichoderma species have been sequenced and are publicly available from the JGI.

Lycoperdon echinatum, commonly known as the spiny puffball or the spring puffball, is a type of puffball mushroom in the family Agaricaceae. The saprobic species has been found in Africa, Europe, Central America, and North America, where it grows on soil in deciduous woods, glades, and pastures. It has been proposed that North American specimens be considered a separate species, Lycoperdon americanum, but this suggestion has not been followed by most authors. Molecular analysis indicates that L. echinatum is closely related to the puffball genus Handkea. The fruit bodies of L. echinatum are

Leotia lubrica, commonly referred to as a jelly baby, is a species of fungus in the family Leotiaceae. L. lubrica was first validly described by Giovanni Antonio Scopoli, but it was later transferred to Leotia by Christiaan Hendrik Persoon. Its relationship with other members of the genus, of which it is the type species, is complicated. The species produces small fruit bodies up to 6 centimetres (2+1⁄2 in) in height, featuring a "head" and a stalk. The youngest fruit bodies are small and conical, but the fertile head quickly grows from the stalk. Ochre with tints of olive-green, the heads

Craterellus cinereus, commonly known as the black chanterelle or ashen chanterelle, is a species of fungus in the genus Craterellus. Found in forests in Europe and North America, it is edible.

Bovista is a genus of fungi commonly known as the true puffballs. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the species of Bovista are now placed in the family Agaricaceae of the order Agaricales. Bovista species have a collectively widespread distribution, and are found largely in temperate regions of the world. Various species have historically been used in homeopathic preparations.

Hericium is a genus of edible mushrooms in the family Hericiaceae. Species in this genus are white and fleshy and grow on dead or dying wood; fruiting bodies resemble a mass of fragile icicle-like spines that are suspended from either a branched supporting framework or from a tough, unbranched cushion of tissue. Their distinctive structures have earned Hericium species a variety of common names—monkey's head, lion's mane, and bear's head are examples. Taxonomically, this genus was previously placed within the order Aphyllophorales, but recent molecular studies now place it in the Russulales.

Tulostoma is a genus of fungi in the family Agaricaceae. Species in the genus are commonly known as stalkballs, or stalked puffballs. Fossils of Tulostoma have been reported from 12 million year old rocks in central England and 13.5 million year old coals from Slovakia.

Stereum is the type genus of the Stereaceae family of fungi, in the Russulales order. Common names for species of this genus include leaf fungus, wax fungus, and shelf fungus. Fungi having a shape similar to a Stereum are said to have a stereoid shape. Stereum contains 27 species that have a widespread distribution.

Geastrum quadrifidum, commonly known as the rayed earthstar or four-footed earthstar, is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. First described scientifically by Christian Hendrik Persoon in 1794, G. quadrifidum is a cosmopolitan—but not common—species of Europe, the Americas, Africa, Asia, and Australasia. The fungus is a saprobe, feeding off decomposing organic matter present in the soil and litter of coniferous forests. The small, tough, fruit bodies are grayish-brown balls that are initially enclosed by a skin, or peridium, made up of four

Spathularia flavida, commonly known as the yellow earth tongue, the yellow fan, or the fairy fan, is an ascomycete fungus. It produces a small, fan- or spoon-shaped fruit body with a flat, wavy or lobed cream to yellow colored "head" raised on a white to cream stalk. It is usually 2–5 cm (3⁄4–2 in) tall. The spores produced by the fungus are needle-like, and up to 95 μm long. Several varieties have been described that differ largely in their microscopic characteristics. The fungus fruits on the ground in mosses, forest duff or humus, and fruit bodies may occur singly, in large groups, or in

Geastrum rufescens, commonly known as the rosy earthstar, is a species of fungus in the family Geastraceae. It was first described scientifically by Christian Hendrik Persoon in 1801. It has a pale pinkish-buff to pinkish exoperidium and rays. The earthstar is found in Europe, North America (including Mexico), and Japan, where it typically grows at the base of old oak stumps.

Lycoperdon umbrinum, commonly known as the umber-brown puffball, is a type of Puffball mushroom in the genus Lycoperdon. It is a saprophyte, and grows mainly in coniferous forests. It is found in China, Europe, Africa, and North America.

Bovista nigrescens, commonly referred to as the brown puffball or black bovist, is an edible cream white or brown puffball. Phylogenetic relationships between Bovista nigrescens and species of Lycoperdaceae were established based on ITS and LSU sequence data from north European taxa.

Physarum is the largest genus of mycetozoan slime molds in the family Physaraceae. They typically thrive in cool, dark, and humid environments, including the bark of trees (often where moss is present), dead twigs, rotting logs covered with moss, leaf litter, and moist forest soils. The name Physarum comes from the Greek word φυσα (physa), which means "blister" or "bubble", referring to the bubble-like appearance of its sporangia.

Leotia is a genus of cup fungi of the division Ascomycota. Leotia species are globally distributed, and are believed to be ectomycorrhizal. They are commonly known as jelly babies because of the gelatinous texture of their fruiting bodies.

Gomphus is a genus of cantharelloid fungi in the family Gomphaceae. Once presumed to be related to chanterelles, molecular study has shown them to be allied with stinkhorns and fairy clubs. The type species of the genus is the pig's ear (G. clavatus). Christiaan Hendrik Persoon named the genus in 1797, but did not assign any species to it at the time. The generic name is derived from the Greek 'γομφος' gomphos meaning 'plug' or 'large wedge-shaped nail'.

Lycoperdon nigrescens, with the synonym Lycoperdon foetidum, commonly known as the dusky puffball, is a type of puffball mushroom in the genus Lycoperdon. It was first described scientifically in 1794 by the Swedish naturalist Göran Wahlenberg. The fruit body grows up to 6 centimetres (2+1⁄4 in) tall and 4 cm (1+1⁄2 in) wide. The caps are shaped somewhat like pears, with spines ranging in brightness, which later break off. The surface is dark between the spines. The stipe has thin strands coming from its base. Visually similar to other species when young, it grows increasingly darker with age

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.

Sphaerophorus is a genus of lichenized fungi in the order Lecanorales. Members of Sphaerophorus are commonly called ball lichens, coral lichens, or tree coral. According to the Dictionary of the Fungi (10th edition, 2008), the widespread genus contains eight species.

Calicium is a genus of leprose lichens. It is in the family Caliciaceae, and has 40 species. The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin (called a mazaedium), hence the common name pin lichen. They are also commonly called stubble lichens. They have been used as indicator species for old growth redwood forests.

Umbilicaria torrefacta is a species of saxicolous (rock-dwelling), foliose lichen in the family Umbilicariaceae. It is an arctic-alpine species with a circumpolar distribution and is widely distributed within the Holarctic realm, specifically within the Palearctic and Neoarctic biogeographical regions. Characteristic features of Umbilicaria torrefacta include the lace-like fringe in its lobes and the plates on the underside of the thallus. One common name, punctured rock-tripe, refers to the distinctive sieve-like perforations on the thallus margins. The species was scientifically described
