FYI
I forward herewith  the preliminary program for the IMC-5 Symposium  
"Genetic Elements in Agaricus bisporus"

For more info contact: <phor...@credit.erin.utoronto.ca>

As you will see in the forwarded message there is a session titled:
"Mitochondria in a wild collection of the white button
mushroom Agaricus bisporus". A.S.M. Sonnenberg. Mushroom Experimental  
Station, Horst, TheNetherlands.

That's why there was a recent question about wild samples of Agaricus  
Bisporus.

Begin forwarded message:

From: "Paul A. Horgen" <phor...@credit.erin.utoronto.ca>

Dear Joost,

Here is the program for my symposium at IMC5.  The papers most likely will  
be given over a two day period with papers dealing with nuclear genetic  
elements on one day and those papers dealing with mitochondria and viruses  
on the second day.

Best wishes,  Paul Horgen
