   Too bad about your cherry trees. This polypore might be the killer,   
   but I don't know much about its behaviour. It's very rare in our   
   country, only growing on oak here, treated and protected as an   
   endangered species. It is more common in warmer climates, I guess.   
      
   I'm quoting Ryvarden & Gilbertson: " White rot of heartwood in the   
   trunk of living oaks, rarely on other hardwoods (that's for Europe).   
   Conspicious brown mycelium develops in the decayed wood in the later   
   stages of decay".   
      
   If you find such mycelium in trunks of the dead cherry trees, you'd   
   know who is to blame. But there are many other diseases on those   
   trees.
