Fly-Speck Leaf Spot (Ophiodothella vaccinii)

Fungus on Vaccinium sp. on a forested trail.

I searched all over the internet, and I could not find this ID. Sometimes textbooks are a much better reference!

This inconsequential disease, which affects species of Gaylusaccia and Vaccinium, is caused by Ophiodothella vaccinii and characterized by distinctive colorful lesions...The pathogen occurs widely in southeastern USA and also in Illinois and California.

  I thought so too. I would have gotten more shots, but it was starting to warm up (towards noon) and I couldn't bend down anymore. The "spots" looked almost silvery in the light. I'm pretty sure this is a Sparkleberry patch, and all of the plants were completely covered! Posted 6 years ago
