Studies on the Chemistry of Lichens. 20. The Chemistry of the Ramalina ceruchis Group.

Abstract
Five spec-ies of the Ramalina ceruchis group were investigated mainly with regard to their contents of aromatic lichen compounds. From all but 1 of these species the authors isolated an unknown diol named ceruch-diol with a suggested formula of C10H52O2 and from 2 of the species, an unknown depside.
