I think it may be squash blossom phytophthora blight or Choanephora flower blight. To confirm we need close up photo of the fungus and also information like is the disease appears on only flower or other parts of plant?

This information will helps us to provide suitable control measures also.

Dr. Ravishankar Narayana commented,
The second photo you uploaded is powdery mildew disease. Anyway since you are growing squash in home garden we would suggest you to remove all infected parts. Dense planting and high soil moisture favors fungal diseases. So please provide proper air circulation around plants and avoid excess watering.

it is powdery mildew. irrigation must be regular and not eccesive, avoid wetting the leaves. you can remove the leaves attacked, but above all I would simply trat the plants with sulfur , like dusting sulfur (sorry about imprecision, I'm not a native english speaker)

This looks like powdery mildew which is a fungal diseases that is very common on squash. It is very likely to transmit rapidly between leaves.

Are you watering with a hose? This is something you should avoid as it will spread the infection.

Remove and burn the leaves or put them in a plastic bag.

Powdery Mildews is common and well prevalent for cucurbits like Squash. The infection spreads rapidly as the spores are transmitted by air, and water.

As a preventive and treatment method, a recommended concentration of silver hydrogen peroxide can be used by foliar spraying on the plants infected.
