Lichen Transplantation on Polyporales Fungi. An Attempt to Verify the Compatibility after Translocation from a Hill Forest to Anthropized City Parks at Livorno (Tuscany, Italy)

Abstract

The transplantation of genus Cladonia terricolous lichens on Polyporales parasitic xylophagous fungi was attempted. Three species of Cladonia (C. pyxidata, C. rangiformis, C. foliacea) have been moved (translocated) from Livorno hill woods (Tuscany, Italy) to some public Livorno parks which suffer by an excessive anthropization. After a short period (a week) of adaptation to the new environment we transplanted thirteen specimens of Cladonia lichens on four different species of Polyporales fungi (Fomitopis betulina, Phellinus torulosus, Stereum hirsutum and Ganoderma applanatum) identified on the trees of the parks. The transplants obtained good engraftment and every periodic qualitative control showed a persistent photosynthetic activity even eight months after the start. Only one transplant (on Ganoderma applanatum) failed due by the toxicity of a secretion after incision. These observations lead us to consider those experiments as a demonstration of the compatibility of the implied tissues on transplantation and also allow us to introduce the difference of the term transplantation (the insert of an organism to another) from the often-confused translocation (relocation of an organism in different habitat). Future checks will indicate how and for how long this artificial association complex might persist.
