Mysterious musty odour in hallway but can't find any signs of moisture

There's a really musty, earthy smell coming from the front door hallway area of my house. I've checked everywhere for any signs of moisture downstairs and sniffed the carpets and floorboards but I can't figure out where it's coming from. Could it be from under the floor? The smell is kind of like wet wood or a musty washing machine. It's been coming and going for six months now and seems to have gotten worse with the hot weather, which makes me wonder if it's dampness. It's mostly just in that one area. Who should I call for help? I'm really at a loss about where to begin. I know the house has some damp spots because there's mould on an upstairs wall. It's become much stronger over the past few days, even lingering on a bag I left on the floor and took to work, and now the smell has stuck to that too :(
