new home owner- what kind of grass do i have?

Hello everyone. I just became a first-time homeowner and moved into a new construction home in northern VA this past October. I'm really trying to take care of my lawn but have realized I have a few challenges. I did not care to ask about what type of grass the builder laid down until now that the spring has arrived (currently waiting for a response). So far I've laid down some milorganite (only to realize I miscalculated the size of my lawn and have to thrown down another bag and a half) and have only mowed once.

1. I've noticed grid lines between the sod patches that were laid. Initially, I thought that's how sod was laid but the grid lines are still visible. The grid lines are more prominent when the grass is wet. How do I get rid of the grid lines?

2. I noticed a brown spot suddenly appear a few days ago before the rain. It was random and is isolated to this one part of my backyard. We do not have pets and our neighbors have not moved in yet. There are also no pets running around. I thought it may have been to the last few days of constant rain causing fungus but if that was the case, I would see brown spots throughout my entire lawn. What could have caused it and how do I fix it?

My backyard faces east so from sunrise until the sun begins to set, the lawn gets full sun for the most part of the day. Thanks in advance for any helps or advice.

This looks like a northern blend. I see fescue in there and what looks like ryegrass.

But I also see some brown areas that look like fungus. I would go to home Depot/Lowe's and trying to get a fungicide asap. Also, avoid watering in the evenings (of course the current rains don't help).

@ericgautier could you move this to the cool season forum?
Yes. Getting the fungicide applied should be your priority so no more lawn dies. What is your height of cut? Could you post images of the dead grass? Picking a fungicide targeted to your fungus is optimal.

At this point try to apply Scotts DiseaseEx.
Diseaseex won't burn your lawn. Don't apply it is there is a downpour of rain in the forecast. Check the label because it might need to be watered after application to activate.

I would keep the hoc at 3in to let the grass breath. I think the nitrogen you applied might help too.

@LawnNerd transition zone fungus is out of my league. It looks like brown patch. What else should he do? I'm assuming tier 1.
