Both my neighbor and I have spots where the grasses turning black, almost
moldy looking. The areas are irregular. I can't see anything like a
fruiting
structure, but it is black, not brown.

If it looks like tiny balls/dots of black on the surface of the blades,
maybe affecting a small patch 6-12 inches wide, then it is probably slime
mold. Slime molds are not pathogenic to the grass, it just looks ugly. It'll
just go away when it gets drier, but it will come back in the future. No
control measure is needed. You could just hose it off.
