  1. Relative peak areas (mean and standard error) for Ca. rufifemur and Cr. modiglianii are given based on FID data from n = 6 (red Ca. rufifemur), 3 (black Ca. rufifemur), and 8 (Cr. modiglianii) colonies. *found in less than 50% of the samples, +tentatively identified, ++position of double bond tentative, § number of substances and their exact structure could not be further determined. Retention indices beyond 44 are extrapolated.
