As part of a larger systematic and taxonomic revision of the genus Sticta in the northern Andes, several species were discovered forming green algal and cyanobacterial photosymbiodemes, seven of which are new to science and are described here—S. lobarioides Moncada & Coca, S. macrothallina Moncada & Coca, S. neopulmonarioides Moncada & Coca, S. phyllidiokunthii Moncada & Lücking, S. pseudolobaria Moncada & Coca, S. pulmonarioides Moncada & Coca, and S. tatamana Moncada & Coca. All species are discussed and illustrated, and a key to species with Lobaria pulmonaria gross morphology is given.
