S ummary An ultrastructural study was made of the interactions between Suillus grevillei (Klotzsch) Sing. and 11 species of ectomycorrhizal hosts in aseptic culture in the absence of glucose. No mycorrhizas were formed between S. grevillei and Betula pubescens Ehrh., Allocasuarina inophloia (F. Muell. & F. M. Bail.) L. Johnson, Picea sitchensis (Bong.) Carr., Picea abies (L.) Karst. Alnus glutinosa (L.) Gaertn. or Pinus nigra Arnold, although the fungus grew in the rhizosphere of some of these and in P. nigra it penetrated and killed adjacent epidermal cells. Mycorrhizas were formed with Larix kaempferi (Lamb.) Carr., Larix decidua Mill, Pinus sylvestris L. and Pseudotsuga menziesii (Mirb.) Franco. However, ultrastructural changes in the host‐fungus interface of associations with the latter two hosts suggest that in both cases the symbionts were not entirely compatible. The role of phenolic compounds in ectomycorrhizal compatibility and specificity is discussed.
