First, I noticed some dead spots in my grass. Wasn't sure what was causing it, but figured maybe it was due to some weed killer I had sprayed.
Then, this morning, while spot applying some weed killer on some Crabgrass and assorted other weeds, I noticed some web/foamy looking stuff covering some of the dead patches! Then, I noticed some bigger areas where the grass has basically been EATEN!! What the heck is this stuff and how do I get rid of it?!!? Help!!! Thank God for BEER! Where's the beer drinking emoticon?!??!!
Man,...you would think having a fabulous lawn in FL, with all the warm weather and rain, would be as easy as falling off a log. My experience in the last year with our new house and observing how many of my neighbors are replacing their lawns with sod says not so at all. Why is that?

It is from gigantic spiders that deposit the toxic foam on your lawn. It dissolves their prey. Usually it is about 5 gallons of foam, but those look like maybe you have a lot of baby spiders.

After looking around on the internet, I think this is what I have: Dollar Spot
Figure 6. Light colored blotchy areas of bluegrass turf infected by the fungi which cause dollar spot. (CLA)
Dollar Spot, caused by the fungi Lanzia spp. and Moellerodiscus spp., produces 23 inch circular patches on creeping bentgrass turf and 4-6 inch circular to blotchy areas on bluegrass lawns. These patches are straw colored (Figure 6). Early in the morning, when the grass is covered with dew, a faint cobwebby growth may be seen on the leaves of affected plants (Figure 7). In the early stages of disease, leaves develop distinct tan-colored spots and bands; quite often a reddish-brown border can be seen on the leaf spots.

Dollar Spot develops at temperatures of 60-85 degrees Fahrenheit with high humidity and low soil moisture. The disease usually develops on lawns which are unfertilized but occasionally occurs on high maintenance lawns under stress. It can be controlled by keeping lawns adequately fertilized and watered and by using a fungicide as necessary. Bluegrass varieties differ in Dollar Spot susceptibility with most being moderately susceptible or moderately resistant.

I'll do it. Man, that post about the spiders was hilarious.
