Franz Gerhard Eschweiler

German botanist (1796-1831).

Franz Gerhard Eschweiler (1796 – 4 July 1831) was a German botanist. Eschweiler was born in Cologne in 1796, the son of a district judge. After graduating from high school in Cologne, he first studied law in Bonn, but then switched to natural sciences and continued his studies at the University of Landshut. There he received his doctorate in medicine in 1824. He then turned to botany and worked on the material collected by Carl Friedrich Philipp von Martius in Brazil. In recognition of this collaboration, the Brazilian shrub genus Eschweilera was named after him. Eschweiler worked in the Regen

Verrucariaceae Eschw. 1824
fungi family in the order verrucariales
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 (Silverskin Lichen) Eschw. 1824
fungi genus in the verrucariaceae family
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.
Trypetheliaceae Eschw. 1824
fungi family in the order trypetheliales
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.
Sclerophyton Eschw. 1824
fungi genus in the opegraphaceae family
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 (Speckled Wart Lichens) Eschw. 1824
fungi genus in the trypetheliaceae family
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 Eschw. 1824
fungi genus in the graphidaceae family
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.
Diorygma Eschw. 1824
fungi genus in the graphidaceae family
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

Haplotrichum Eschw. 1824
fungi genus in the botryobasidiaceae family
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.

Anthracothecium prasinum (Anthracothecium Lichen) (Eschw.) R.C. Harris 1987
fungi species in the pyrenulaceae family
Anthracothecium prasinum is a corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. It has a pantropical distribution, occurring across tropical regions. It forms black, carbonized (blackened) perithecioid fruiting bodies (pseudothecia) that produce brown, muriform (multichambered) ascospores.
