fungus id? with several pics
yesterday evening when i was cutting the grass, i noticed several areas of fungus on my grass blades. the areas, at this time, are all on the slope from the ditch to the road. we've had ALOT of rain lately and my yard is the lowest in this particular group of homes.
yesterday, the fungus appeared white with a slight purple tint. this morning only one spot remained white looking while the others appear very dark, nearly black.
i've never tried any type of lawn care other than mowing infrequently until this year. i began an organic program in about april and have applied SBM twice. i've been closely mowing the centipede (i guess it's centipede) and watering deeply once a week....except for the past 3 weeks in which we have been getting rain about every 2-3 days it seems.
i suppose i should start with a baking soda mix and spread some corn meal? any other tips?
here are 2 resized pictures and links to 2 much larger close up pictures.
