Candelariella (Candelariaceae) in western United States and northern Mexico: the 8-spored, lecanorine species

Abstract

This paper treats 12 Candelariella species occurring in western North America characterized by having lecanorine apothecia and 8-spored asci. Six new names are proposed: C. aggregata, C. californica, C. complanata, C. corallizoides, C. deppeanae and C. immarginata. Candelariella terrigena and C. deflexa are treated as synonyms of C. citrina and C. aurella, respectively. Candelariella kansuensis is newly reported from North America. Distribution maps for western North America are presented for all species. Candelariella citrina, C. rosulans and C. terrigena are lectotypified. A key to Candelariella in western North America is presented.
