Found this in a vacant home. It's "growing" on finished OSB in a basement ceiling. Right next to an obviously leaking HVAC joint. Clearly condensation from the cool HVAC supply has allowed something to grow on the OSB. I'm calling it " some type of growth ", but has anyone else seen this? and if so, what is it? algae?

gato,

I'd feel comfortable calling it a WDO.

BTW, what is a "leaking HVAC joint"?

The OSB looks positively saturated to my eye.

I found a long narrow ceiling stain once that was due to a condensate drain that was fractured along its length in an attic space. Looked for all the world like it had been stepped on.

It sounds like the entertainment center I made in high school.
