Description of leaf:
the leaf is an ellipse with serrated edges, measuring 126 mm from the tip of the leaf to the base of the unstraightened stem. The widest point, measured slightly diagonally across the center was 37mm.
Observation 1:
observed milky white colored streak on the sun facing side of the leaf of a local weed. The streak appears removable by aggressive rubbing with water. Black streaks are present in some of the infected areas. The streak appears erratic, and while most of the streak appears to follow along the veins of the leaf, some parts of the streak do cross over the veins while travelling up the leaf. The white streaks can be faintly seen through the underside of the leaf. The blackened areas are not visable through the leaf.
Observation 2:
Upon closer inspection, white streak was still present in scrubbed areas except where the leaf was heavily damaged by washing. This would suggest it is not a growth or residue leaft on the leaf, but is something underneath the surface. The track is nearly circular, however, has branches that indicate ends. Some sections are thicker,~1mm, and gradually slim down ~.2mm. The thicker areas are where the black streaks are more concentrated, and the thickest area has a small tan sliver similar in appearence to that of a dying leaf in the fall.
