Abstract: 2 tables. 3 figures. [Study of 31 specimens by HPLC detected 13 different compounds. "Six of them are well-known lichen acids which occur in nearly all the species; but proportions are different and constant for each species." A key to species in the Rhizocarpon superficiale group is included.]
