Opegrapha halophila Brodo & Tønsberg is described based on material from British Columbia, Canada, and Alaska, U.S.A. It is distinctive due to its lirellate apothecia, the (mainly) discrete soralia, the production of roccellic/angardianic acid, and its habitat on coastal rocks in the salt spray zone. A key to sorediate species of Opegrapha is provided.
