Abstract: 14 fig. [Both epilithic (Acarospora, Paraparmelia chlorea, Peltula capensis, & Xanthoparmelia marroninipuncta) and endolithic lichens (Lecidea & Sarcogyne) were studied in the field. "Maximum photosynthetic rates of the investigated species were found at temperatures between 20°C and 30°C, far higher than the recorded optimum temperatures for lichens from temperate and and desert regions."]
