Abstract. Review of recent literature and studies on large and mainly recent collections of lichens and lichenicolous fungi led to the addition of 35 taxa to the flora of Belgium, Lux- embourg and northern France: Abrothallus buellianus, Absconditella delutula, Acarospora glaucocarpa var. conspersa, Anema nummularium, Anisomeridium ranunculosporum, Artho- nia epiphyscia, A. punctella, Bacidia adastra, atrofusca, Caloplaca britannica, Cer- cidospora macrospora, Chaenotheca laevigata, Collemopsidium foveolatum, C. sublitorale, Coppinsia minutissima, Cyphelium inquinans, Involucropyrenium squamulosum, Lecania fructigena, conferta, L. pannonica, L. xanthostoma, Lecidea variegatula, Mica- rea micrococca, Micarea subviridescens, M. vulpinaris, Opegrapha prosodea, stuppeum, Placynthium stenophyllum var. isidiatum, Porpidia striata, Pyrenidium actinellum, Thelopsis rubella, Toninia physaroides, Tremella coppinsii, Tubeufia heterodermiae, Verru- caria acrotella and Vezdaea stipitata. Three species are to be deleted from that flora: , Fuscopannaria saubinetii and Squamarina oleosa.
