Help identify a musty smell in a bathroom?

Our small main floor 2-piece bathroom has had a musty smell for the last couple of months. We can't seem to identify the source and aside from the smell there is no sign that anything is wrong. We had a plumber in and he spotted a very small amount of (orangy coloured) mould inside the toilet tank, but even after cleaning that up with MoldEx the smell has not abated. What could it be?

Other pertinent information:
The smell comes and goes. At some points it is quite strong, and at others it is barely present at all. I haven't been able to identify any correlation between our activities and the smell, though I think that the smell is reduced when the toilet is flushed more frequently.
There is no sign of water anywhere. There's a finished basement below and there is nothing on the ceiling there, nor is there any sign of water around the toilet. The plumber confirmed this.
The smell is confined to the bathroom. You can't smell it outside the bathroom at all, on any side (two sides are accessible, including the wall that the toilet is on), or below. The sink does not smell, nor is there any sign of mould anywhere near it.
The bathroom does not have any windows and does not get much, if any, natural light. It may have been under-used for a couple of months before we moved in the spring; the people we bought from had already moved into their new place but were, we think, using this house occasionally for laundry and moving things out slowly.
I'm not sure if there is any other information that would be useful. We do live in a somewhat humid climate. The toilet has been used regularly since we moved in in early April, but the smell didn't really hit us until maybe August or September.
