Thin layer chromatography patterns of Rhizopogon species and their possible use as a taxonomic criterion

Thin layer chromatography pattern s of Rhizopogon species and their possible use as a taxonomic criterion. The possibility of characterizing Rhizopogon by thin-layer chromatography was
investigated. Fifty-eight fruitbodies were sampled. The most detailed chromatograms were obtained from ethanol extracts and plates running with n-butanol-water-acetic acid (4:1:1), examined with ultra-violet light
and marking out fluorescent spots. This preliminary study showed 17 chromatogram patterns, ten of which
were clearly different and characteristic of only one current species (R. evadens, R. occidentalis,
R. pachydermus, R. pannosus, R. rocabrunae, R. roseolus, R. subsalmonius, R. verii, R. Villosulus and
R. Vinicolor) . The chromatogram patterns may be a great aid in differentiating Rhizopogon species.
