For several years I have been innoculating various conifer 
species (Thuja, Thujopsis, Juniperus, Chamaecyparis, etc) with 
spores from mycorrhizal fungi prior to transplanting into my 
small tree nursery.  I started out with spores collected by a 
colleague from Tuber gibbosum and other truffle species, but have 
since started using a commercial innoculant composed of 15 
different fungal species.  Treated seedlings exhibit a marked 
increase in vigor, rate of establishment, growth and color as 
compared to non treated seedlings.  Now I plan to start a couple 
hundred oak seedlings and I am trying to determine what fungal 
species establish a beneficial mycorrhizal relationship with the 
genus Quercus, and, ideally, a commercial source for such an 
innoculant.  FWIW, this is a non-commercial land reclamation
