220 taxa of lichens are reported from four localities in Inglefield Land in NW Greenland. Rhizocarpon anseris is new to Greenland; seven taxa are new to W Greenland, viz. Aspicilia mashiginensis, Candelariella dispersa, Collema substellatum, Gypsoplaca macrophylla, Lepraria lobificans, Rhizocarpon intermediellum and Xanthoria elegans var. splendens. 42 taxa are new to NW Greenland, viz. Acarospora schleicheri, Adelolecia pilati, Arctoparmelia separata, Aspicilia cinerea, A. mastrucata, Baeomyces placophyllus, B. rufus, Buellia punctata, Candelariella terrigena, Cladonia borealis, C. phyllophora, Collema glebulentum, C. undulatum var. granulosum, Diploschistes muscorum, Endocarpon pulvinatum, Fulgensia desertorum, Ionaspis suaveolens, Lecanora fuscescens, Lecidea silacea, Lecidella bullata, L. euphorea, Lepraria frigida, Leptogium lichenoides, Lobothallia alphoplaca, Melanelia stygia, Miriquidica garovaglii, Ochrolechia androgyna, O. lapuënsis, Pannaria hookeri, Pertusaria geminipara, Porpidia flavicunda, P. speirea, Protoblastenia calva, Rhizocarpon disporum, R. praebadium, Rinodina archaea, R. cacuminum, Staurothele fissa, Toninia tristis subsp. scholanderi, Umbilicaria nylanderiana, Verrucaria ceuthocarpa and Vestergrenopsis isidiata. In addition, northern extensions of 169 taxa in NW Greenland are presented. Geology and climate of the area are briefly treated and selected plant communities more or less rich in lichens are discussed.
