Species of Lactarius encompass one of the larger known genera of ectomycorrhiza (ECM)-forming basidiomycetes. Cosmopolitan in distribution, several hundred taxa are currently recognized which collectively play an important role as late-stage ECM colonizers of woody trees and shrubs found in arctic, montane, temperate and tropical ecosystems. Because of their high degree of host specificity, fastidious in vitro growth requirements, and their role as late-stage ECM colonizers, species of Lactarius have not been examined intensively by ECM researchers. Detailed information is lacking on the colonization and development of ECM on host root systems, and the subsequent physiology and ecology of the host-fungus symbiosis. This chapter attempts to summarize current knowledge in order to present a starting point for further studies on members of this important genus.
