HEEEEEEEELP
  This morning at 0800 i checked my courgettes and noticed a pale yellow ,wet soft foamy growth at the base of one. I have just checked again 1230 and its gone from the size of a saucer to yhe size of a dinner plate. i`ve never seen or heard of this before,its like something from outer space.

no idea what it was but, one of our round ones went like that, I just took it off and the rest have been ok  :)

Never heard of that one, but I know courgettes can weep copiuosly when cut - which makes me think it might have been nibbled by something small and prolific and is weeping through very small holes - I'm thinking froffy coffee makers here.
 
Obviously outdoor plants have the benefit of being able to drink vast amounts of water this year, so maybe it has a hyperactive root system which is contributing?

I'd be tempted to cut the offending fruit/stem off cleanly and hope for the best. ???

If it hardens, maybe you could use it for cavity wall insulation? ;D

Is this underneath the whole plant? Or just affecting one fruit or one stem?

Thanks Melbourne12
         It seems to be affecting the base of one plant and spreading over leaf stems,has`nt reached the fruit yet.

I'm slightly puzzled by this.  If it's wet, it sounds like a bacterial infection of some sort.  But it might be a fungus.  Try spraying with dithane (or bordeaux) and see if that stops it.  If so, it's fungal.

If it's some sort of bacterial growth (maybe carried by insects) then I suspect that the only remedy is to remove that plant completely.
