the usfs wood science lab in madison, wi (1 gifford pinchot drive) puts 
out a lot of papers on fungal degradation (applications include paper 
pulping, wood protection and toxics degrafation). the stars seem to be the
white rot family, tho the brown rot family is also studied.

Greetings, Joel.  Sorry for the delay in sharing my information on your 
request below.  Nevertheless, I think that you would be very interested 
in the following references:

 1) Solbraa, K., M.D. Sant, A.R. Selmer-Olsen, and H.R. Gislerod.  1983.  
Composting soft and hardwood barks.  BioCycle, Vol. July/August:44-48,59.

 2) Hoitink, H.A.J., E.B. Nelson, and D.T. Gordon.  1982.  Composted bark 
controls soil pathogens of plants.  Ohio Report 67(1):7-10.

 3) Wood Products for Fertilizer.  1945.  Bulletine No. 7, NE Wood 
Utilization Council, New Haven, Conn.

 4) Composting section of the Appropriate Technology Microfiche Library, 
Volunteers in Asia, Stanford, CA, 1-800-648-8043.  Their information 
describes some very interesting successes in East Africa with applying 
sawdust to field soils as a fertilizer!  I too had questions of possible 
nitrogen immobilization but I suppose their successess can partially be 
explained by research such as the following:

 5) Hill, N.M, and D.G. Patriquin.  1990.  Evidence for the involvement 
of Azospirillum brasilense and Helicomyces roseus in the aerobic 
nitrogen-fixing/celluloytic system from sugarcane litter.  Soil Biol. 
Biochem. 22(3):313-319.

Joel, I noticed that someone did suggest using the references from Paul 
Staments for specific fungal inoculants, and I agree wholeheartedly on 
that.  He probably is one of our most kowledgeable resources persons on
this subject.  If you are interested too in more ideas about results from 
microbial screening trials on woody substrates, check out the following 
reference:

 6) Kirk, T.K., T. Higuchi, H.M. Chang (eds.).  1980.  Lignin 
Biodegradation: Microbiology, Chemistry and Potential Applications.  CRC 
Press, Boca Raton, FL.

Good luck on your trials.  I too feel that wood-based compost is an 
under-utilized resource.  I would be very interested in hearing about 
your experiences.  Later...
