Dying Grass

 
Hi everyone, Im posting on behalf of my Dad who is having problems with
his lawn.  He has patches of grass that are dying.  When he dug up a
patch of the dead grass there is a white powdery substance in the soil
below (he thinks it might be a fungus).  He has dug up many patches
where the grass has died and it is always present.  He has also dug up
areas where the grass is healthy and no white powdery substance.  He
lives in the UK, South East and his garden is very well maintained.  All
ideas, suggestions and any advice gratefully received.


Thank you!
