Please help, brown spots in lawn - Pictures

I am not sure what is causing these spots. I do not know much about lawns. I had a company come out early spring to fertilize. I would like to try to take care of this myself. Iíve had one person tell me to fertilize and another person tell me to aerate and overseed. My yard is watered regularly and is mostly in shade. Any ideas? Thanks.

Hi,
I will give a WAG that it's Dollar Spot (Mollerodiscus spp.,
Lanzia spp.) on Perrenial Ryegrass, right down the mower path.
Don't fertilize,irrigate or cut untill you have put down a curitive Fungicide, takes the "Fun out of Fugus" LOL. Reccomend Thiopynate-methal product, Clearies 3336 etc.........
Best of luck.
Regards,

either my eyes are really bad, or the pictures are very good.

I don't see any 'spots'.. It looks like bentgrass starting to get twisted and uproot.

Dollar spot is usally small, and circular.

can you get a picture of a grass blade REALLY upclose?

Dollar Spot....come on. This is definetly NOT dollar spot. This could be a whole range of things. When wqas the last time you renovated this lawn? Had a soil test done? Did you apply fert lately? All of these are relitive to the answer but for those little patches of turf, I would take a core from those areas and I would probably bet that this is a subsurface problem more than anything. If it was red thread, you wouldn't be asking this question.

Never renovated, haven't needed to. I can look into a soil test.. is that something common to have done local or do you mail samples out? Fert has not been applied since early this spring.
