Abstract: 11 fig. ["Laboratory studies under controlled conditions showed clearly depressed net photosynthesis (NP) of water saturated thalli of Fulgensia fulgens, Lecanora muralis, Psora cerebriformis and Xanthoria calcicola. The depression was severe and present at all light levels and temperatures tested. In contrast, Diploschistes muscorum and D. diacapsis had no depression of photosynthesis at high WC."]
