Unfortunately, there are no effective treatments for this kind of problem - the toadstools/mushrooms are just the fruiting bodies of an underground, extensive root system which may have been present in the turf when you bought it. You could try contacting the company who supplied the turf to get it replaced, otherwise you'd need to remove the toadstools daily - they should pass after 2 weeks or so, but will return next year. If you have more than one variety present, then they may be a problem in spring and again in Autumn.

juyst mow them down as bamboo sais they dont last long andwill actualy out grow yourgarden eventualy as the underlying plant for want of a better word grows outwards hence ringworm which is a fungus on animals grows in circles .

I'm not to keen on the idea of mowing them down - some mushrooms spread by means of spores from their gills, and mowing them encourages spread of the spores - I always prefer to twist them off and place in a bag to prevent possible spore spread. However, if there are lots in such a large area, then I guess there's no choice

well thats maybe a better idea bamboo . id still mow them as i quit like them myself not that ive got any lawn lol .

Might be an idea to get them identified - a few are very poisonous, some not good for you and some quite harmless. If they turn out to be harmless ones you will worry less.

good thinking but there normaly only poisoness if there ingested normaly .
