Punctelia subrudecta ( Basionym : Parmelia subrudecta ) is a species of leaf lichen from the Parmeliaceae family that ismore common in Central Europe andgrows on tree bark.

description

The rosette bed of the lichen is white-gray to bluish-gray (slightly greenish when wet), sometimes with a brownish tinge, especially at the periphery. The diameter reaches up to 5 cm. At the edge slightly ascending lobe patchy be soralia adapted from whitish, punctate Pseudocyphellen emerge. At the edges there are partially border-like sorals, especially inside the camp. The underside of the thallus is usually pale. Apothecia are very rare.

distribution

Punctelia subrudecta is found in southern and central Europe (there up to an altitude of about 1000 m) and penetrates as far as southern Scandinavia. It thrives mainly on moderately to strongly acidic bark of free-standing deciduous trees, for example on fruit trees or in sparse oak stands .

As a “moderate Mediterranean” species, Punctelia subrudecta is used to monitor local climate changes by means of lichen mapping.
