description
The whitish to gray, mostly thin-crusty thallus ( often lightening towards the clearly delimited edge) breaks up towards the center of the bed in an irregular, large-area, granular, sorediose manner . Apothecia are very rare (then black, white frosted and sunken, up to 0.4 mm in diameter).
distribution
Phlyctis argena is common from southern Scandinavia to the Mediterranean area. It has a broad ecological amplitude and grows preferentially on smooth to cracked bark of deciduous trees, sometimes on coniferous wood, and rarely on silicate rock.
