Analysis of surface structures of Cladonia mitis podetia in historic and recent collections from Greenland
Udgivelsesdato: March 1995 Field observations in Greenland combined with a scanning electron microscopical survey have revealed a hitherto undescribed correspondence in the distribution of a brownish colour and a crust-like surface structure formed by hyphae at exposed parts of the shoot tips of pod...
