Stem Galls on Lathyrus japonicus

[Darryl Martin]

Hi, I am looking for information which will help identify the causative 
agent for producing large stem galls on Beach Pea (Lathyrus japonicus). 
The gall tissue is full of golden-yellow coloured, kidney shaped, 
thick-walled spores, which are 50 micrometres across.  There are no 
mycelium present.  Any suggestions of what species this could be would 
be greatly appreciated.
