Abstract

Lepraria eburnea is shown to comprise three morphologically indistinguishable chemotypes, containing either protocetraric acid, psoromic acid, or neither substance, in addition to alectorialic acid. The holotype of L. frigida contains protocetraric acid and alectorialic acid, and is thus united with L. ebumea under the latter name.
