When driving west along VA 57 toward Chatham, I noticed that the cement wall across the street from the stop sign was marked with splotches of yellow paint. As the years passed, I eventually became aware of my mistaken assumption about yellow paint. Enlightenment transformed my thoughts after I had observed this yellow coating on the moist side of trees, rocks, wet boards, etc. It seems that I had finally learned about Protococcus vulgaris — known worldwide as an alga that is basically unicellular. It reproduces only by cell division and is readily spread by wind, water, and insects almost throughout the world where subaerial life can exist.
