Kunkel, G 1980: Microhabitat and structural variation in the Aspicilia desertorum group (lichenized Ascomycetes). - American Journal of Botany67: 1137-1144. [RLL List # 108-52 / Rec.# 10574] Keywords: ASPICILIA/ MORPHOLOGY/ COLORADO/ VARIATION/ LECANORA
Abstract: 14 figures. 1 table. [Study of crustose and fruticose forms of this species from western Colorado showed that " ... for single populations, microenvironmental variation in substrate, temperature, light intensity and water availability is directly related to continuous morphological variation. Functional variation with habitat is evident in growth form, stage of apothecial development, calcium oxalate pruinosity, anatomical disposition of unidentified crystalline material, cortical anatomy, maximum thallus water content (or water-holding capacity) and relative thickness of hyphal wall."]
