Does anybody know which species the lichen on the picture is!
http://www.danbbs.dk/~gro_poul/billedkasse.htm Who told you it is a lichen? It looks like a liverwort to me. Liverworts are related to mosses & have the same reproductive system, but they look like pieces of green rubber.

It looks like a liverwort to me. Liverworts are related to mosses & have the same reproductive system, but they look like pieces of green rubber. But lichens can be thalloid and rubbery as well. This one, for example. It is indeed a lichen, and not a liverwort. [But superficially it's a very liverwort-like lichen]. It clearly looks to me to be a member of the lichen genus _Peltigera_. Possibly P. canina? The pale structures are the characteristic fruiting bodies of the lichen fungus. These lichens are especially rubbery, perhaps because they contain the blue-green cyanobacterium _Nostoc_. IIRC, the familiar species _Peltigera canina_ or "dog lichen" is named for its often toothlike fertile bodies at the lobe tips [these are not always present], but there are other similar species. [As I recall, early herbalists thought the toothy-looking lichen ought to be good for treating dog bites and rabies (doctrine of signatures)...] http://www.robertthompsonphotography.com/page_77.htm http://www.nmc.edu/~jmedlin/p_canina.html http://www.southamptoncameraclub.co....tml-advanced/6 2.htm http://www.nawwal.org/~mrgoff/photoj...8frogpelt.html http://www.bioimages.org.uk/HTML/P153473.HTM http://www.bioimages.org.uk/HTML/P163352.HTM http://www.rook.org/earl/bwca/nature...peltigera.html http://www-biol.paisley.ac.uk/resear...tigera_horizon talis.html http://www-biol.paisley.ac.uk/resear...tigera_membran acea.html http://www-biol.paisley.ac.uk/resear...tigera_britann ica.html http://www.floraislands.is/latflora.htm Many thanks for the answer. After studying the species I now suppose it is Peltigera didactyla. Kind regards Poul Evald Hansen |
