The two new lidien depsidones methyl-virensate and 5-Cl methyl-virensate were found in the lichens Pseudocyphellaria physciospora and Pseudocyphellaria granulata. Structure elucidation of the new compounds was carried out using UV/VIS-, ¹H-NMR- and El-mass-spectroscopy. In TLC studies 5-Cl methyl-virensate may be confused with pannarin. The close relationship of the two new lidien substances to atranorin and Cl-atranorin is discussed.
