Fungi named in 1824

Xylaria polymorpha, commonly known as dead man's fingers, is a cosmopolitan saprobic fungus. It is characterized by its elongated upright, clavate, or strap-like stromata poking up through the ground, much like fingers.

Xylaria hypoxylon is a species of bioluminescent fungus in the family Xylariaceae. It is known by a variety of common names, such as the candlestick fungus, the candlesnuff fungus, carbon antlers, or the stag's horn fungus. The fruit bodies, characterized by erect, elongated black branches with whitened tips, typically grow in clusters on decaying hardwood. The fungus can cause a root rot in hawthorn and gooseberry plants.

Fusarium oxysporum (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the F. oxysporum complex are soil borne pathogens of plants, especially in agricultural settings.

The Verrucariaceae are a family of lichens and a few non-lichenised fungi in the order Verrucariales. The lichens have a wide variety of thallus forms, from crustose (crust-like) to foliose (bushy) and squamulose (scaly). Most of them grow on land, some in freshwater and a few in the sea. Many are free-living but there are some species that are parasites on other lichens, while one marine species always lives together with a leafy green alga. Several characteristics of the spore-bearing structures, the ascomata, define the family, including their perithecioid form–more or less spherical or

Dermatocarpon is a genus of lichens in the family Verrucariaceae. Members of the genus are commonly called stippleback lichens because they have fruiting structures called perithecia that are flask-shaped structures embedded in the nonfruiting body (thallus), with a hole in the top to release spores, causing an appearance of being covered with small black dots. Its species are told apart chiefly by spore size, the colour and texture of the lower surface, and whether the epinecral layer gives a pruinose bloom.

Phragmidium mucronatum is a plant pathogen that causes rose rust.

The Trypetheliaceae are a family of mainly lichen-forming fungi in the order Trypetheliales. The family consists almost exclusively of corticolous (bark-dwelling), crustose lichens with an almost strictly tropical distribution.

Graphiola is a genus of fungi belonging to the family Graphiolaceae. The genus has cosmopolitan distribution.

Sclerophyton is a genus of lichen-forming fungi in the family Opegraphaceae. It has about 15 species. The genus was circumscribed by German lichenologist Franz Gerhard Eschweiler in 1824, with Sclerophyton elegans assigned as the type species.

Astrothelium is a large genus of corticolous (bark-dwelling) lichens in the family Trypetheliaceae. The genus is characterized by a corticate thallus and diverse ascomata structures, which can be simple, aggregated, or forming pseudostromata. Astrothelium is also notable for the carbonized walls of its ascomata, the so-called textura intricata (i.e., tightly interwoven) arrangement of cells in these walls, and various forms of distoseptate, transparent spores.

Leiorreuma is a genus of script lichens in the family Graphidaceae. It has 18 species. The genus was circumscribed by Franz Gerhard Eschweiler in 1824, with Leiorreuma hepaticum assigned as the type species.

Heterosphaeria is a genus of fungi in the family Helotiaceae. The genus contains 6 species.

Graphiola phoenicis is a plant pathogen of the palm Phoenix canariensis.

Fusarium sulphureum is a fungal plant pathogen infecting maize and hemp.

Erysiphe penicillata is a plant pathogen that causes powdery mildew on alder. It has also been reported to have affected certain species of Corylus including Corylus sieboldiana, Corylus colurna and Corylus heterophylla, although this is doubtful following Bradshaw et al. (2021).

Diorygma is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world. These lichens form paint-like crusts on bark and rock that range from chalky white to light green, with elongated, pencil-like slits containing their spores that may flex and branch across the surface. The genus was established in 1824 for tropical script lichens with large, many-celled spores, but molecular studies in the 2000s and 2010s expanded it significantly

Naevia is a small genus of fungi in the family Arthoniaceae. Unlike most members of their family, these fungi do not form lichens because they lack algal partners and instead obtain nutrients by decomposing dead bark material. They appear as tiny black dots scattered across the smooth bark of trees and shrubs, where they act as early colonisers of fresh bark surfaces. The genus was historically confused with the related lichen-forming genus Arthonia, but modern molecular phylogenetics studies have confirmed that Naevia represents a distinct evolutionary lineage of non-lichenised fungi.

Botryobasidium is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps (fruit bodies) are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution.
