Lichens of Belgium, Luxembourg and northern France
Lecanora laevis Poelt |
This species, which is very close to L. horiza, was mentioned from Belgium: Brab. by Arts & Hoffmann (1995) and from Belgium: Mosan by Barkman (1958) (see also Lambinon 1959) and Lambinon (1963: 244), but no correctly identified specimen has been examined by us.
