Well last week I started seeing the brown spots on the leaves, and I just figured that it was one of those strawberry diseases that happen. But then i went out yesterday and it is turning into the yellow with the brown on the leaves in big areas. it looks just like the picture on here https://en.wikipedia.org/wiki/Phomopsis_obscurans
I wouldn't be surprised as I get every fungal disease under the sun at my house. even my perennials get blight or something!
