Phylotypic Characterization of Mycobionts and Photobionts of Rock Tripe Lichen in East Antarctica
Saxicolous rock ripe lichens that grow on rocks in the East Antarctic fellfields were sampled for phylotypic characterization of its constituent mycobionts (fungi) and photobionts (algae and cyanobacteria). The rock tripe lichen-forming fungal and algal phylotypes were classified under the common li...
