Abstract: 27 fig. 8 tab. 1 appendix [Detailed examination of the secondary chemistry of 56 species in the genera Umbilicaria and Lasallia. "The study reported here 1) confirms many previous chemical identifications, 2) analyzes additional taxa, 3) identifies other compounds new to the family, and 4) compares HPLC and TLC methodologies for the identification of these compounds in fragments from herbarium specimens. The chemistries of Lasallia and Umbilicaria are compared and reassessed in light of these findings." Various chemical correlations observed support the separation of Lasallia and Umbilicaria.]
