Experimental studies with foliose macrolichens: fungal responses to spatial disturbance at the organismic level and to spatial problems at the cellular level during drought stress events,

Improved culture methods and the application of cryotechniques in light and electron
microscopy have allowed new insights at the organismic and cellular levels in mycobiont-photobiont
relations of selected lichen species. Growth, regenerative capacity, and the ability to cope with spatial
disturbances were tested in the foliose macrolichens Xarlthoria parietir~a and Parmelia sulcata. These
mycobionts can sense and partly correct an inverted position and thus insure adequate illumination for
the …
