Parmelia sulcata , sometimes called Sulcat lichen in German, is a type of leaf lichen that is common in Central Europe.

description

The species has blue-gray "leaflets" with sometimes almost angular demarcation. The leaflets show a network of whitish lines towards the edge ( pseudocyphella ). These can later break up into fissure tensorals that serve for vegetative distribution. On the dark underside, the blackish adhesive fibers (rhizines) extend to the edge of the bearing. Fruit bodies ( apothecia ) are only rarely formed.

distribution

Parmelia sulcata is widespread and occurs mainly on the bark of deciduous trees, and occasionally on rock. Due to its relative insensitivity to air pollutants and nitrogen compounds, it is also often found in cities, even if in some cases poorly developed.

standardization

Nitrogen levels in Parmelia sulcata allow conclusions to be drawn about the ammonium deposition and the total nitrogen deposition . Due to its ability to enrich nitrogen proportionally to the supply of airborne, reactive nitrogen compounds in your thallus , it is used in standardization for the detection of immission effects. This can be done, among other things, to check the effect of nitrogen-containing immissions in the vicinity of corresponding systems or to document the actual status. The guideline VDI 3957 Part 18 deals exclusively with nitrogen enrichment in Parmelia sulcata .
