Fungi named in 1826

The Clavariaceae are a family of fungi in the order Agaricales. Originally the family contained most of the clavarioid fungi (club and coral fungi), but in its current sense is more restricted, albeit with a greater diversity of basidiocarp (fruit body) forms. Basidiocarps are variously clavarioid or agaricoid (mushroom-shaped), less commonly corticioid (effused, crust-like) or hydnoid (with pendant spines).

The Hydnaceae are a family of fungi in the order Cantharellales. Originally the family encompassed all species of fungi that produced basidiocarps (fruit bodies) having a hymenium (spore-bearing surface) consisting of slender, downward-hanging tapering extensions referred to as "spines" or "teeth", whether they were related or not. This artificial but often useful grouping is now more generally called the hydnoid or tooth fungi. In the strict, modern sense, the Hydnaceae are limited to the genus Hydnum and related genera, with basidiocarps having a toothed or poroid hymenium. Species in the

Saproamanita vittadinii, commonly known as the Vittadini's lepidella, is a European saprophyte mushroom classified in the genus Saproamanita. Unlike some Amanitas, this species is known to occur without accompanying woody plant symbionts. It has a general aspect somewhat between Macrolepiota and Armillaria, but it is characterized by a pure white colour overall (whilst those genera are brownish) and by the squamous (scaly) covering of cap and stipe. In 2019, amateur mycologist Denis Pouclet experimentally ate 30 grams (1.1 oz), fresh weight, of S. vittadinii from France without reported

The Rhytismataceae are a family of fungi in the Rhytismatales order. It contains 55 genera and 728 species.

The Stereocaulaceae are a family of lichen-forming fungi in the order Lecanorales. It contains five genera. Species of this family are widely distributed in temperate boreal and austral regions.

Lophodermium is a genus of fungi within the family Rhytismataceae. The genus contains 145 species and has a global distribution. Species of this genus are usually observed producing zone lines, conidiomata and ascomata on dead fallen leaves, but at least some are known to colonize living leaves. In many cases they then live inside the colonized leaf as a symptomless endobiont, where they are regarded as detritivores utilising dead plant matter. In a few cases they may kill all or part of the leaf prematurely, and there is a substantial literature dealing with those species as plant pathogens.

The Roccellaceae are a family of mostly lichen-forming fungi in the order Arthoniales, established by the French botanist François Fulgis Chevallier in 1826. Species in the family exhibit various growth forms, including crustose and fruticose (shrub-like) thalli, and diverse reproductive structures. Roccellaceae species typically have disc-like (apotheciate) or slit-like (lirellate) fruiting bodies, often with distinct blackened (carbonised) margins. Molecular phylogenetics studies have revealed considerable genetic diversity and complex evolutionary histories within the family. Convergent

The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family.

Cetraria aculeata, the spiny Iceland lichen, is a dark brown to black fruticose lichen in the family Parmeliaceae. First described by Schreber in 1771 as Lichen aculeatus, it was transferred through several genera before being placed in Cetraria. The thallus forms shrubby tufts up to 5 cm (2.0 in) tall and reproduces mainly by fragmentation rather than ascospores. The species has a wide, bipolar distribution, occurring from the maritime Antarctic to the high Arctic and, at intermediate latitudes, in montane, steppe, and coastal habitats. Phylogeographic evidence suggests it evolved in the

Lophodermium pinastri is a fungus in the genus Lophodermium. Like most species in the genus, it is an endophyte and saprophyte of pine (Pinus spp.) needles.

The Lecideaceae are a family of lichen-forming fungi in the order Lecideales. It contains about 30 genera and roughly 250 species. A major distinguishing characteristic of the family is the lecideine form of the fruiting bodies: typically circular, dark, and without a thalline margin. Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous—they live on other lichens. Lecideaceae lichens tend to grow on rocks, wood, and soil. Several Lecideaceae species accelerate the weathering of rock surfaces, a process known as

The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods has helped to establish its current placement in the order Caliciales. Caliciaceae contains 39 genera and about 670 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species. Most Caliciaceae grow on bark, dead wood, or rocks. Some members of

The Umbilicariaceae are a family of lichenized fungi in the Ascomycota. Species of this family are known from a variety of climates, including temperate, boreal, austral, and warmer montane regions. The family contains five genera and 53 species.

The Agaricaceae are a family of basidiomycete fungi and include the genus Agaricus, as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.

The Aspergillaceae are a family of fungi in the order Eurotiales which are commonly known as the blue and green molds. The family includes the commonly known and observed genera of Aspergillus and Penicillium amongst other lesser known mold genera but also includes larger ascomycete fungi such as Penicilliopsis.

The Hysteriaceae are a taxonomic family of fungi and the only extant family of the order Hysteriales. Members of the Hysteriaceae are defined by the possession of a sexual structure called the hysterothecium, an elongated structure that opens by a longitudinal slit and releases sexually produced spores. The family is widely distributed, with many species found in temperate regions, and most are saprobic on wood and bark, although a few are parasitic on plants.

The Dothideaceae are a family of fungi in the order Dothideales. Species in this family have a widespread distribution, especially in tropical areas.

Xenodochus is a genus of rust fungus in the family Phragmidiaceae, containing the following species: Xenodochus minor Xenodochus carbonarius, Schltdl., 1826 (Great Burnet Rust) Both species parasitise members of the Rose family in the genus Sanguisorba, but the genus has a highly discontinuous distribution, with X. minor known from sub-arctic Alaska and X. carbonarius from Europe.
