THE LICHENS OF BELGIUM AND LUXEMBOURG. AN ANNOTATED CHECKLIST 115
conspurcatosorediosa (Harm.) Diederich
Corticolous, mainly on Fagus, also on Acer,
Carpinus and Quercus, only in the industrialized
SW of Luxembourg, on dust-impregnated bark.
B - . L Lorr.: R.
The nomenclature and taxonomy of this species
require clarification. It possibly represents corticolous
populations of L. scabra.

elaeochroma (Ach.) Choisy
Syn.: Lecidea elaeochroma (Ach.) Ach., L. glomerulosa
(DC.) Steud., L. olivacea (Hoffm.) A.

limitata auct., non Scop., incl. Lecidella achristotera
(Nyl.) Hertel & Leuckert, L. euphorea
(Flörke) Hertel
Corticolous, very common, mainly on smooth bark
(e. g. of Carpinus), never on conifers, toxitolerant.
B Mar.: CC, Fl.: CC, Camp.: R, Brab.: AR, Mosan,
Ard., Lorr.: C. L Ard.: AC, Lorr.: C.
The taxonomic value of the sorediate thalli, sometimes
recognized as f. soralifera (Erichsen) D.
Hawksw., requires further studies. This forma is
known from B Mar.: AR, Fl.: R, Mosan: RRR. L
Ard.: RRR, Lorr.: RR. F Lorr.: RRR.

Fraxinus, Populus, Sorbus domestica) in rather
eutrophic conditions, or on Fagus in forest in
acidic conditions.
B Mosan: RRR (1968), Ard.: R. L Lorr.: R. Probably
