Abstract: 1 figure. [Study on Pseudocyphellaria dissimilis from New Zealand showed no changes in "...the degree of desiccation damage in response to alternations in available respirable reserves ...." Authors conclude that "... the algae noramally transfer the bulk of their photosynthetic products to the fungus and the algae normally constitute less than 10 percent of the weight of the thallus, changes in the respiration rate of the whole lichen are presumed to reflect alternations in the fungal respirable reserves. Thus the algae appear to retain insufficient respirable reserves for the repair of desiccation damage and hence pretreatment designed to alter the reserves of the whole thallus do not change the desiccation sensitivity of the lichen."]
