Abstract: 8 figures. ["Data is presented which shows that Peltigera canina var. praetextata from a woodland floor can rapidly acclimate to low of high light levels and thus maintain a given level of photosynthesis irrespective of the leaf canopy status. This photosynthetic adjustmanet taken placve naturally in the field during leaf fall in October." The response of Peltigera scabrosa is similar, but populations of P. aphthosa seemed to be adapted to either low or high light levels depending on the source of the plants.]
