Abstract

This study was focused on lichenicolous fungi from the Antarctic region whose diversity is not yet well known. The sampling was carried out in the maritime Antarctica, South Shetland Islands, Livingston Island, during a trip in 2018. In total, more than one hundred species of lichenicolous fungi were collected, of which a selection has been studied here. The remaining species will be studied in future papers. As a result of our morphological and molecular studies (based on ITS rDNA, LSU rDNA, and mtSSU), three new species are proposed: Arthonia olechiana on Steinera olechiana, Sphaeropezia neuropogonis on Usnea, and Sphinctrina sessilis on Pertusaria excludens. Moreover, the new combinations Bryostigma excentricum on Lepraria and Raesaenenia usneae on Usnea are also proposed.
