What you are probably seeing is pink snow mold. This is sometimes seen in the spring after the snow melts and is more common when heavy snow has fallen on unfrozen ground. Snow mold is generally not a serious problem and usually doesn't require any fungicide application. The normal recommendation is simply to lightly rake the area to allow the grass to dry more quickly. This also disrupts the growth of the fungi. In most cases, the grass will slowly recover and green up - just a little slower than the rest of the lawn. Sometimes small patches of grass may be killed by snow mold and these areas can be over-seeded and then top dressed with a thin layer of good quality compost.
