Taxa described in 1818

Cordyceps is a genus of ascomycete fungi (sac fungi) that includes over 260 species worldwide, many of which are parasitic. Diverse variants of cordyceps have had more than 1,500 years of use in Chinese medicine. Most Cordyceps species are endoparasitoids, parasitic mainly on insects and other arthropods (they are thus entomopathogenic fungi); a few are parasitic on other fungi.

Calathea is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or (like their relatives) prayer plants. About 200 species formerly assigned to Calathea are now in the genus Goeppertia. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates.

Shepherdia, commonly called buffaloberry or bullberry, is a genus of small shrubs in the Elaeagnaceae family. The plants are native to northern and western North America. They are non-legume nitrogen fixers.

genus of fungi

Leptosia, commonly called wood whites, is a genus of pierid butterflies. It is the only genus of the tribe Leptosiaini. Leptosia are found in Africa, except for Leptosia nina, which ranges from India to Australia, and Leptosia lignea, which is found only on Sulawesi. All have a frail appearance and broad rounded wings. They are only distantly related to the Palearctic wood whites Leptidea (Dismorphiinae).

Aphidius is a genus of insects of the family Braconidae.

Stalachtis is a genus of metalmark butterflies (family Riodinidae). It is currently the only member of the tribe Stalachtini, but many metalmark butterflies are yet to be unequivocally assigned to tribes, so this might change eventually.

Lasiocephalus is a genus of South American flowering plants in groundsel tribe within the sunflower family. The genus was shown to be part of Senecio and predominantly occurs in tropical alpine-like regions.

Piscicola is a genus of leeches belonging to the family Piscicolidae. The species of this genus are found in Europe and Northern America.

Phleogena is a fungal genus in the Phleogenaceae family. The genus is monotypic, containing the single species Phleogena faginea and is found mostly widespread in northern temperate areas, but is occasionally found in southern areas.

Dothidea is a genus of fungi belonging to the family Dothideaceae. The genus was first described in 1818 by Elias Magnus Fries. The type species is Dothidea sambuci.

Lophium is a genus of fungi in the family Mytilinidiaceae. It was described by Swedish mycologist Elias Magnus Fries in 1818.
