Fungi named in 1815

Schizophyllum commune is a species of fungus in the genus Schizophyllum. The mushroom resembles undulating waves of tightly packed corals or a loose Chinese fan. Gillies or split-gills vary from creamy yellow to pale white in colour. The cap is 1–4 centimetres (3⁄8–1+5⁄8 in) wide with a dense yet spongey body texture. It is found on rotting wood throughout the world. This fungus is an opportunistic environmental pathogen.

Amanita fulva, commonly called the tawny grisette or the orange-brown ringless amanita, is a basidiomycete mushroom of the genus Amanita. It is found frequently in deciduous and coniferous forests of Europe and possibly North America.

Verpa conica, commonly known as the bell morel or the early morel, is a species of fungus in the family Morchellaceae. Sometimes mistaken for a true morel, this species is characterized by a cap resembling a thimble that is freely attached to the stipe.

Taphrina is a fungal genus within the Ascomycota that causes leaf and catkin curl diseases and witch's brooms of certain flowering plants. One of the more commonly observed species causes peach leaf curl. Taphrina typically grow as yeasts during one phase of their life cycles, then infect plant tissues in which typical hyphae are formed, and ultimately they form a naked layer of asci on the deformed, often brightly pigmented surfaces of their hosts. No discrete fruit body is formed outside of the gall-like or blister-like tissues of the hosts. The asci form a layer lacking paraphyses, and

Rhizina undulata, commonly known as the doughnut fungus or the pine firefungus, is a species of fungus in the family Rhizinaceae. The fruit bodies of the fungus are dark purple brown with a bright yellow margin, crust-like and attached to the growing surface by numerous root-like yellow rhizoids. R. undulata has a cosmopolitan distribution, and commonly occurs on clearings or burned areas throughout central and northern Europe, North America, northern Asia, and southern Africa. It is parasitic on conifer seedlings, and has caused considerable damage to tree plantations worldwide.

Cronartium is a genus of rust fungi in the family Cronartiaceae. They are heteroecious rusts with two alternating hosts, typically a pine and a flowering plant, and up to five spore stages. Many of the species are plant diseases of major economic importance, causing significant damage. Species, hosts and natural distribution Cronartium appalachianum: Pinus virginiana, Santalaceae. Eastern North America. Cronartium arizonicum: Pinus ponderosa and related pines, Scrophulariaceae. Western North America. Cronartium comandrae: Pinus subgenus Pinus, Santalaceae. North America. Cronartium

Rhizoctonia is a genus of fungi in the family Ceratobasidiaceae. Species form thin, effused, corticioid basidiocarps (fruit bodies), but are most frequently found in their sterile, anamorph state. Rhizoctonia species are saprotrophic, but some are also facultative plant pathogens, causing commercially important crop diseases. Some are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi. As of 2025, the synonymisation of several genera under a unified Rhizoctonia was formalised, and the genus now includes

Coniophora is a genus of fungi within the order Boletales. Basidiocarps (fruit bodies) are corticioid (patch-forming). There are 20 species in the genus, which has a widespread distribution. One notable member is the cellar fungus (C. puteana), which causes wet rot in wood. Molecular analysis has revealed that there are cryptic species in the fungal lineages Coniophora olivacea, C. arida, and C. puteana.

Rhizina is a genus of ascomycete fungi in the order Pezizales. The genus was circumscribed by Elias Magnus Fries in his 1815 work Observationes mycologicae, with R. undulata as the type species. R. atra and R. lignicola were added to the genus in 1921 and 1925, respectively, by Australian botanist Leonard Rodway.

Erysiphe heraclei is a species of powdery mildew in the family Erysiphaceae. It is found across the world, where it infects members of the family Apiaceae (umbellifers). It has also been recorded on Billardiera in Australia.

Epicoccum is a genus of fungi belonging to the family Didymellaceae. The genus has cosmopolitan distribution.

Asteroma is a genus of pathogenic fungus in the family Gnomoniaceae, containing several species that cause leaf spot and canker on plants such as goldenrod, primrose, and Erythronium.

Geoglossum difforme is a species of earth tongue fungus in the family Geoglossaceae. It is found in Europe and North America. It is listed as critically endangered in Denmark and endangered in Sweden. It is inedible.

Cyphelium is a genus of crustose areolate lichens with cup-like apothecia filled with sooty black spores. The genus is in the family Caliciaceae . The genus has a widespread distribution, especially in north and south temperate regions, and contains about 12 species. Members of the genus are commonly called soot lichens.
