The distinction between Menegazzia cincinnata and M. valdiviensis (Parmeliaceae)
The aim of the present investigation is to assess the status of Menegazzia cincinnata and Menegazzia valdiviensis, two closely related species from southern South America. The main characters used previously to segregate the two species are discussed and evaluated. The main conclusions are that the...
