Hi all. So I've noticed this white furry looking stuff on the rim joist area of basement. Nothing's ever moist or wet down there and RH is never over 40%
There's two spots that look like old cob webs but further back in there I see it on subfloor but on subfloor it's a bunch of tiny furry looking balls about 1/4" or smaller in size (see pics).
Is this white mold or cob webs or what?!? Thx![IMG_4656.JPG IMG_4656.JPG](https://cdn2.imagearchive.com/houserepairtalk/data/attachments/21/21477-da5fac36ad3c76a316b5dce1a8eb97d7.jpg)
