Myriolecis bandolensis morpho. sur ciment ou béton.
This morph. differs from the type only by its occurrence on cement or concrete in aerohaline or xeric supralittoral zones. Relatively nitrophilous, it is often associated with Lecanora campestris, Candelariella aurella, Verrucaria nigrescens, Caloplaca sp., etc.
N.B. In this situation easy to confuse with Lecanora campestris but the latter species has more numerous apothecia and its thallus is K+ yellow (see photograph).
