Abstract: 3 figures. 1 table. [Studies on Sticta latifrons and Pseudocyphellaria amphisticta. "Both species exhibited an increase in transport resistance at high thallus water contents and an increase in both transport and carboxylation resistances at low water contents. However, at ambient CO2 concentrations carboxylation processes were the dominant factors limiting photosynthesis at all, except high, water contents."]
