Abstract
A taxonomic study of corticolous species of Lecanora in the Sonoran Desert region containing usnic acids and not belonging to Lecanora s. str. is pres ented. Descriptions, notes on the ecology and distribution and a key to the 17 species recognized within the area are included. Lecanora coniferarum P rintzen, L. latens Printzen, L. perconfusa Printzen, and L. substrobilina P rintzen are described as new to science. The following new combinations are proposed: Lecanora densa (Sliwa & Wetmore) Printzen, L. laxa (Sliwa & Wetm ore) Printzen, and L. americana (B. de Lesd.) Printzen.
