Hi

My institute is currently involved in elucidating a new anomaly in  
mushroom farming: the formation of clusters.

So: Is there any evidance for the presence of mycoplasms or lower  
fungi such as plasmodiophora to cause disease in higher  
basidiomycetes.

Clustering is the anomalous growth of mushrooms in a big tight group  
consisting of 5 to 10 fruit bodies on a single clubroot like stipe. 

Any educated guesses about the possible cause of this clustering  
effect are gratefully invited.
