Lactarius (Basidiomycota) in Papua New Guinea 2. Species in tropical-montane rainforests

Abstract

Collections of Lactarius Pers. from tropical-montane rainforests of Papua New Guinea (dominated by fagaceous, ectomycorrhizal trees) are described. Nineteen new taxa are proposed, and three previously described species are included. A key to the species, illustrations and discussion about the infrageneric position of the presently known Papuan Lactarii are presented.
