This revision is based on critical macroscopic and microscopic studies of about 450 Greenlandic collections of the tribus Hygrocybeae, in Greenland represented by the genera Camarophyllopsis and Hygrocybe (s. l.). The collections are assigned to 29 taxa. Hygrocybe rubrolamellata and H. conica var. aurantiolutea are described as new. H. coccinea (Schaeff.: Fr.) P. Kumm., H. marchii (Bres.) F.H. Møller and H. coccineocrenata (P.D. Orton) M.M. Moser are excluded from the Greenlandic basidiomycota. The concepts of H. biminiata Kühner, H. coccineocrenata (P.D. Orton) M.M. Moser, H. rhodophylla Kühner, H. substrangulata (P.D. Orton) P.D. Orton & Watling and H. turunda (Fr.: Fr.) P. Karst. are revised.
The phenology, ecology and distribution patterns of all species are discussed. The grassland slopes in S Greenland and the oceanic dwarf-scrub heaths and fens in S and SW Greenland are two centres of distribution. The species composition of tribus Hygrocybeae in Greenland shows much affinity to that of the Alps and NW‑Europe.
