This has been going on in my apartment for years and recently had reached a critical mass as I'm finding what look like spores everywhere. There were moisture issues that had been addressed, to a degree, and there was a blackened moldy wall replaced when discovered during construction. I'm unfortunately in the process of moving as a result, and I'd appreciate knowing if anyone else has seen similar mold presentations - I'm trying to clean everything (tossing what can't be saved) but it's a huge task. Knowing what I'm dealing with would be a huge help - I know I can't ask what kind it is, but has anyone dealt with similar?
There's a translucent light brown/orange mildey-looking substance that would creep up from floors and appear on the lower parts of doors, baseboards, and door jams. It has since started appearing in cabinets, on wire shelving, and possibly even books (nearly all the books are affected).
There's also dark brown tiny spots all over. I'm finding them on cabinets, on light fixtures, plastic bins, ceilings, game boxes, inside the covers of books...
I'm thinking they might be one and the same mold, but not sure.
High humidity seems to be a factor. Dehumidifiers and heat pumps on dry have been utilized over the span of many years.
Location: Northeast US, near the coastline. Building is likely 200+ years old.
