If the place has been re-sided and they used roofing felt behind the siding versus building paper, there may be petroleum distillates bleading out of the felt onto the siding.

Looks like 'tannin' staining from ice-dam leaks to me...

The mulch that the neighbor was referring to is artillery mulch but that doesn't look like it. Artillery mulch leaves little black dots.
Does look like mold however, did you checked these areas with the pins?

One has to wonnder if the leak has not been fully addressed.
Or, could it really be an insulation issue, as in the lack there of behind the shower causing some wicked condensation.
Just a couple of thoughts...

Around here a house that old usually has a rosin paper WRB if it has any at all. If they used asphalt impregnated felt under the new siding above, any moisture in the wall will be driven out through the more permiable older areas of the wall. That kind of tannin stain is the result. I would wager that there is/was wet wood in the wall well up into where they new siding is.

There was a leak for sure sometime in the past as indicated by the damaged/stained subfloor in the basement and the destroyed frame and sill around the window beneath.
I did test for moisture, however the home has been vacant for 6 months so I was told. As far as residing, portions were resided, but most of the new siding was above these stains. The neighbor also mentioned that the stains were there a long time and much worse prior to any repairs.
That's what has me puzzled.
- Orinally really bad stains
- Repairs made to bathroom (new tiled surround)
- Fresh paint at exterior
- Vacant for 6 months (no one using shower)
Maybe residual moisture in wall cavity is pushing resin/asphalt through siding?
I'll just report what I see on this one.
Thanks!

In all the accounts listed above by you and other members, all seem like valid possiblities.
Sometimes I feel like our curiosity gets us to investigate further than we need to.
I personally would have used a moisture meter just to see if it was wetter than areas around it. Checked the eave and roof closely in this area, then written up that further investigation is needed.
If the sub structure was still wet when they made the repairs, and no one has lived in the home since, I could be condensation from a greenhouse effect of the house being sealed up and is now sweating. The damage before that could have been from the actual leak. but if moisture was sealed in, that could lead to sub structure rot. We can't do distructive testing to find out if that is the case but it should definately be looked into further.

It looks like a situation where the bath tub (now tub /shower) is against the exterior wall and the tub enclosure or window penetration is leaking into the wall cavity
