Blistered Cup fungus

I have Blistered Cup fungus around the bottom of my runner beans. I understand it lives in horse manure. This is what I put in the trench under my runner beans. I have searched Internet but I can't find any information as to whether this is  bad for my plants or my allotment plot. I have removed the fungus that I can see, bagged it up and removed from the site. Can anyone give any information on how to get rid of it and should I get rid of my runner bean plants

As far as I know its a fairly harmless inedible fungus, that grows on rotting manure.

As its growing ON the manure it shouldn't do any harm to your beans.
The only indication that this may be giving you is that the manure was a bit fresh when you used it!

If you really dislike it you could use a fungicide, or just keep removing it.

Let us know what happens!
