Description: Deutsch: Schwielenflechte (Physcia stellaris) (Mitte) zusammen mit Gelbflechte (Xanthoria parietina) auf einem Ast einer Linde (Fraxinus excelsior) in Frankfurt nahe dem Mainufer. Die Flechten-Spezies wurden zugeordnet mit Hilfe des Buches "Farbatlas Flechten und Moose" von Volkmar Wirth und Ruprecht Düll, Eugen Ullmer GmbH, 2000, ISBN 3-8001-3517-5. Bitte infromieren Sie mich, wenn Sie der Meinung sind, dass es sich um andere Spezies handelt. English: Physcia stellaris (middle) together with common yellow lichen Xanthoria parietina (left and right) on a branch of an ash (Fraxinus excelsior) in Frankfurt near the river Main (Germany). Lichens are interesting life forms: fungi hold algae captive in a way, that their relationship is in-between a symbiosis and purely parasitic, also described as controlled parasitism. The lichen species were assigned using the book, "Farbatlas Flechten und Moose" by Volkmar Wirth and Ruprecht Düll, Eugen Ullmer GmbH, 2000, ISBN 3-8001-3517-5. Please contact me, if you think that they are different species. Date: 17 June 2012. Source: Own work. Author: Norbert Nagel.
