The Lichens and Lichenicolous Fungi of Belgium and Luxembourg ...

T
THE LICHENS OF BELGIUM AND LUXEMBOURG. AN ANNOTATED CHECKLIST 11
The area covered by the checklist
he territory dealt with in the present work includes Belgium, the Grand Duchy of
Luxembourg and the neighbouring areas of northern France (Fig. 1). These include the
following departments (numbers used for administrative purposes): Nord (59), Ardennes
(08), Meuse (55, northern part only), Meurthe-et-Moselle (54, northern part only) and
Moselle (57). The Netherlands and Germany are not included, although the occurrence of
the rarest or the most interesting species is mentioned for those localities very close to the
borders.
Below, we briefly describe the phytogeographical districts of our area of study, focusing on
the habitats they can provide for the lichen flora. The districts are those of the ‘Nouvelle
Flore de la Belgique, du Grand-Duché de Luxembourg, du Nord de la France et des
Régions voisines’ (Lambinon et al. 1993: XXI-XXIV) (Fig. 2). Our synthesis is drawn from
the work of Lambinon (1969: 81-90) and Tanghe (1975).
