These two white puffs started growing on the side where I had taken a swab sample from an old disintegrating wooden fence beam. They started off growing as small spots on the plate and were fairly inconspicuous. The pink mold came over from the other side of the plate and surrounded these specs, but they persisted and now are growing above the vast sea of pink. The top side is a pure white and the bottom is yellow-ish, leading me to believe that this is an example of Clonostachys rosea.
