Heinrich Gustav Flörke

German botanist (1764-1835).

Heinrich Gustav Flörke (24 December 1764, in Altkalen in Mecklenburg – 11 June 1835) was a German botanist and lichenologist known for his detailed studies of lichens, particularly within the genus Cladonia. A professor of natural history at the University of Rostock, Flörke contributed to early systematic and floristic research, publishing extensive annotated collections of dried herbarium specimens known as exsiccatae. He continued editing Johann Georg Krünitz's influential Oekonomische Encyklopädie after Krünitz's death, although his tenure was marred by controversy due to disputes with pub

Cladonia floerkeana (Gritty British Soldiers Lichen) (Fr.) Flörke 1828
fungi species in the cladoniaceae family
Cladonia floerkeana is a species of fruticose lichen in the family Cladoniaceae. The species produces distinctive bright red spore-bearing structures (apothecia) on thin, upright stalks (podetia) that can be variably branched. These stalks may be smooth, rough, or covered in tiny scales. The species was first described by Elias Magnus Fries in 1824 as Cenomyce floerkeana and later transferred to the genus Cladonia by Heinrich Gustav Flörke in 1828. C. floerkeana is closely related to Cladonia macilenta, from which it is distinguished by its lack of soredia and its chemical properties.

Stereocaulon dactylophyllum is a species of saxicolous (rock-dwelling), fruticose lichen in the family Stereocaulaceae. It was first scientifically described by Heinrich Gustav Flörke in 1819. Flörke mentions that the original specimens were collected in 1797 on mossy rocks at the Rehberger Graben and near Sankt Andreasberg on the Harz Mountains, and also on the Fichtel Mountains. It is now known to be widely distributed, having been recorded in Asia, Europe, Greenland, eastern Canada, and the eastern and central United States. The lichen is characterised morphologically by the coralloid,
Baeomyces carneus (Northern Beret Lichen) Flörke 1821
fungi species in the baeomycetaceae family
Baeomyces carneus is a species of terricolous and saxicolous (ground- and rock-dwelling), squamulose lichen in the family Baeomycetaceae. This pale green to light brown lichen forms crusty patches on soil, rotting wood, or sheltered rocks, and spreads mainly through tiny detachable flakes rather than spores. It has a wide distribution across the boreal forests of North America and also occurs in Europe, New Zealand, Hawaii, and the West Indies.
