Molecular phylogenies using 1–4 gene regions and information on ecology,morphology and pigment chemistry were used in a partial revision of the agaric family *** phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are:Acantholichen,Ampulloclitocybe,Arrhenia,Cantharellula,Cantharocybe,Chromosera,Chrysomphalina,Cora,Corella,Cuphophyllus,Cyphellostereum,Dictyonema,Eonema,Gliophorus,Haasiella,Humidicutis,Hygroaster,Hygrocybe,Hygrophorus,Lichenomphalia,Neohygrocybe,Porpolomopsis and Pseudoarmillariella.A new genus that is sister to Chromosera is described as *** were made at the ranks of subfamily,tribe,genus,subgenus,section and *** present three new subfamilies,eight tribes(five new),eight subgenera(one new,one new combination and one ***.),26 sections(five new and three new combinations and two ***.)and 14 subsections(two new,two ***.).Species of Chromosera,Gliophorus,Humidicutis,and Neohygrocybe are often treated within the genus Hygrocybe;we therefore provide valid names in both classification *** used a minimalist approach in transferring genera and creating new names and ***,we retain in the Hygrophoraceae the basal cuphophylloid grade comprising the genera Cuphophyllus,Ampulloclitocybe andCantharocybe,despite weak phylogenetic *** include Aeruginospora and Semiomphalina in Hygrophoraceae based on morphology though molecular data are *** lower hygrophoroid clade is basal to Hygrophoraceae s.s.,comprising the genera Aphroditeola,Macrotyphula,Phyllotopsis,Pleurocybella,Sarcomyxa,Tricholomopsis and Typhula.
