Help! White fungus on newly sprouted seed!

Hi All,
The city had to tear up part of my yard and re-seeded - but it has been so hot and humid that I had a white cottony fungus in 4-6" circular patches when I checked it this morning. The grass sprouted on Sunday and I've been watering it each morning - as the surface soil dries out in the sun. But our humidity is so high that the dew has everything sopping wet until about noon. Even where I haven't been watering.

Any ideas? I don't know what type of grass seed as the city planted it - but in our area KBG and fescues are most common.

PS I have been putting down coffee grounds, and had done corn, soybean and alfafa meal earlier in the season. I hadn't planned on having to deal with new grass during the hottest part of summer.

If it's staying wet until noon from the dew, you can probably cut back on the water.

Thanks bpgreen. I probably will. I've never grown grass from seed as you can probably guess.

I'd read somewhere to water it twice a day the first 2-3 weeks. So I thought the early morning waterings were showing some restraint...sigh! Any ideas on how to undo the damage, stop the fungus from spreading???

I don't have a lot of first hand experience with fungus since I'm in the desert, but I've read that spreading ordinary corn meal (like you buy at the grocery store) at a rate of 20 lbs per 1000 sq ft can help.
