Ochrolechia kerguelensis sp. nov. from the Southern Hemisphere and O. antarctica reinstated from the synonymy of O. parella
Ochrolechia kerguelensis Ertz & Kukwa is described as new to science from the subantarctic islands of Kerguelen. It is characterized by pruinose ascomata, usually 4-spored asci, large ascospores of 50–90 × 32–56 µm, the production of gyrophoric acid only in the apothecia and the lack of variolar...
