Abstract: The author has found the agarics Hygrophorus pacificus Smith & Hesler (one locality) and H. hyacinthinus Quél. (three localities) in Kuusamo, northern Finland. The former is new to Europe, the latter new to northern Europe. The characters of these species, especially those which separate them from their closest relatives, are presented and partly amended, and their habitat ecology and distribution are d iscussed. Both species are characterized especially through a strong fragrant odour. H. hyacinthinus occurs in forest on calcareous soil associated with Picea or Abies and possesses a boreal-montane distribution restricted to Europe. H. pacificus occurs in coniferous forest apparently always associated with Picea and has a boreal-montane distribution in North America with one locality in northern Europe.
