Résumé :

In 1995, a survey of the corticolous macrolichens has been carried out in the Brussels-Capital Region considered for more than one century as a "lichen semi-desert". Contrary to all expectations, the 26 sampling sites distributed throughout the urban area have yielded 18 species most of which are associated with white willow, sycamore and hybrid black poplar growing in humid areas. But even in drier sites, all of the 25 examined tree species, except beech, are not devoid of epiphytic macrolichens. This observation might be interpreted as a progressive phenomenon and a consequence of SO2 depollution.
