What sorts (if any) of edible fungi (or other species) can survive lowlight conditions?

Basically, in the event of a blotting out of the sun á la an impact winter, what sort of food source (if any) could be used to sustain humanity?

In my universe, underground/makeshift greenhouses would not be infeasible, but more desirable would be the ability to farm some sort of edible food on the surface. Would fungi / what would be able to survive in these lowlight conditions?

Then, let's say we'd be able to give them a limited amount of exposure to artificial light. How much light would they need per day?

Also, In the Metro 2033 series they grow fungi in the subway tunnels.
