  • Israel PÉREZ-VARGAS (a1), Consuelo HERNÁNDEZ-PADRÓN (a1) and Pedro L. PÉREZ DE PAZ (a1)

Abstract

Pertusaria etayoi, found on lava flows and basaltic rocks from the Canary Islands, is described as new to science. It is the only species in the group of saxicolous Pertusaria with verruciform apothecia and 2 rough-walled ascospores to contain thiophaninic acid. A description of the species is given together with notes on its chemistry, distribution, ecology and taxonomy. Possible related lichen taxa are discussed briefly.
