Abstract. Studies of mainly recent collections of lichens and lichenicolous fungi led to the addition of nine taxa to the flora of Belgium, Luxembourg and northern France: Aphanopsis coenosa, Biatora efflorescens, Burgoa splendens, soralifera, limonia, Phoma physciicola, wirthii, glabrescens var. glabrescens and Xanthomendoza oregana. Seven additional species were reported in recent publications: Caloplaca conversa var. fallax, Ceratobasidium bulbillifaciens, Hainesia brevicladoniae, H. longicladoniae, reddenda, Oxneria huculica and Zwackhiomyces peltigerae. New to Belgium: Cornutispora ciliata, Polycoccum pulvinatum, Thelopsis rubella and Zwackhiomyces physciicola; new to Luxembourg: Bacidia carneoglauca, Enchylium limosum, Lempholemma chalazanum, Lichenothelia convexa, Polycoccum slaptoniense, Rinodina pityrea and Thelenella muscorum. Additional notes are given on some rare and threatened spe­cies. The following new combination is proposed: Xanthomendoza huculica (S. Y. Kondr.) Diederich (basionym Oxneria huculica).
