Type specimens in REN-ABB


The list of types in REN

A "type" is the valid  representative of a species. Each newly discovered species needs to be described (in Latin) and a type specimen has to be deposited in an official herbarium. There is just one main type per species, the holotype. However, there are also other types (isotype, lectotype, etc.). In REN ABB we have several holotypes and isotypes.

More information about the types in Cladonia may be found on the web page "Names in the Cladoniaceae" ( or in  Ahti, T. 1993. Names in current use in the Cladoniaceae (lichen-forming Ascomycetes) in the ranks of genus to variety. In: Greuter, W. (ed.). Regnum Veg. 28: 58-106.
