TELOSCHISTES FLAVICANS hae been found to contain beside8 anthraquinone pigments, a colourless substance. The former have been found to vary in composition, l-3 but the colourlesa substance seems to have been the same in all the samples of the lichen and by employing column chromatography (magnesium carbonate) nearly l$ yield on the dry weight of the lichen could be secured.
