Soral (lichen)
So-called lippensorale in Hypogymnia physodes Parmelia sulcata, the cracked formations on the surface are so-called Spaltensorale
Soral (Plural: Sorale) is a term from the Flechekunde (Lichenologie).
Sorals are ridges on the thallus surface of lichen, which serve vegetative propagation (lichens are symbioses of algae and fungi). Through them, Soredien (Singular: Soredium), which are formed in the lichen interior, are discharged to the outside. These multiplication units are diaspores and usually form a small "packet" (appearing under the magnifying glass grainy or mealy), which consists of fungal hyphae, which envelop the cells of the algae partner. For example, For example, by rain, wind, or animals, new lichens can grow on suitable subsurface.
Depending on the appearance of the Sorel, different forms are distinguished, For example "Lippensoral" (as in the case of Physcia tenella or Hypogymnia physodes), "Bortensoral" (as in the case of genuine pulmonary lichen (Lobaria pulmonaria)), "Helmsoral" (as in Physcia adscendens) or "Spaltensoral"
