A 13C-NMR study of 56 species of Umbilicariaceae shows that pustulan-type polysaccharides, previously known from only 11 species, are apparently constant in the family. For most species analyzed, the high concentration of this single linear homoglucan enables its detection in very small samples, in this case primarily the same ones used earlier to identify secondary products by HPLC and TLC. For chemical analysis, pustulan is extracted with boiling water. Using sections prepared for SEM, however, even cold water extracted some pustulan from two species containing only trace amounts of secondary products, but not from two others having them in high concentrations. The thallus structure, observed with SEM, was altered in the first pair, but scarcely changed in the second. Pustulan is less readily extracted from thalli with high concentrations of secondary products.
