At present 40 species of Pseudocyphellaria are recognised in the New Zealand flora, ten of which appear to be new and will be described elsewhere. In the present account, the 30 published taxa are listed alphabetically and, where applicable, the synonymy of confused species is discussed. The following 13 new combinations are made: P. coerulescens (Mont.), P. condensata (Zahlbr.), P. coriacea (Hook.f. & Taylor), P. delisea (Fee), P. dissimilis (Nyl.), P. hookeri (Church.Bab.), P. lividofusca (Krempelh.), P. moruagnei (Church. Bab.), P. multifida (Laurer), P. poculifera (Miill.Arg.), P. psilophylla (Miill.Arg.), P. pubescent (Miill.Arg.), and P. rubella (Hook.f. & Taylor). 85 taxa are reduced to synonymy with known species.
