Bulletin de la Société des naturalistes luxembourgeois 110: 75-92. Abstract. Studies on large and mainly recent collections of lichens and lichenicolous fungi led to the addition of 19 taxa to the flora of Belgium, Luxembourg and northern France:Buelliella poetschii, Caloplaca arcis, C. coralliza, C. dichroa, C. oasis, C. pyracea, Gyalecta derivata, Lem- mopsis pelodes, Lepraria ecorticata, Leptogium aragonii, L. pulvinatum, Leptorhaphis laricis, Minutoexcipula tephromelae, Monodictys epilepraria, Phoma grumantiana, Polyblastia goth- ica, Ramalina canariensis, Sphaerellothecium cladoniae and Vouauxiella verrucosa. Another 22 additional taxa are reported in recent publications: Acarospora rufescens, Arrhenia pelti- gerina, Bacidia caesiovirens, B. subfuscula, B. sulphurella, Caloplaca itiana, C. ulcerosa, Car- bonea supersparsa, Chaenothecopsis ochroleuca, Endohyalina insularis, Lecanora helicopis, L. sarcopidoides, L. subsaligna, Lepraria zeorinica, Lichenochora paucispora, Parmotrema pseu- doreticulatum, Physcia tribacioides, Sphaerellothecium araneosum, S. parmeliae, Strigula sych- nogonoides, Verrucaria poly sticta and V. xyloxena. The following species have to be deleted from the checklist: Acarospora smaragdula, Caloplaca britannica, C. lithophila, Lecanora albel- lula (syn. L. piniperda), Lepraria leuckertiana, Lichenochora inconspicua and Parmotrema stuppeum. Abrothallus acetabuli, Lepraria jackii, Phaeosporobolus usneae, Telogalla olivieri and Usnea flammea are newly reported for Belgium, and Chaenotheca brachypoda, C. hispidula, Fellhanera viridisorediata, Lepraria sylvicola, Leptorhaphis epidermidis, Lichenoconium pyxida- tae, Tubeufia heterodermiaeand Verrucaria hegetschweileri for Luxembourg. 1.
