Bean Fungi?

My pole beans have a bean fungi - the kind that lives in the soil and kills off my seedlings.

I have pulled them out and replanted the beans, but I fear without innoculant, I will continue to lose them.

However some have survived and are beginning to climb the tee-pee. Maybe it isn't a fungus, maybe it was just the heat or bad watering practices. Who knows? I just hope I don't lose anymore. It's getting late to still be planting my pole beans.
