CONCLUSIONS 



A population of clones belonging to the genus Armil- 

 laria has been defined. All isolates comprising the clones 

 are secured in contaminant-free archival collections. An ef- 

 fective technique of challenging large numbers of isolates 

 to delineate clones has been demonstrated and verified. 

 Grouping of clones, based on the behavior of certain 

 species, suggests the Northern Rockies is home for at 

 least four species of the genus. Many avenues appear to 

 be open for the confirmation of species affiliation in 

 populations of vegetative isolates. Complete understanding 

 of the life cycle, genetics, and ecological role of the Armil- 

 laria complex will come with a thorough investigation of 

 vegetative populations obtained from healthy as well as 

 diseased stands.
