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!
From Page 44 of “Diseases of Trees and Shrubs - 2nd Edition” by Wayne A. Sinclair and Howard H. Lyon:
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.

Yes, I was much happier with this one! I got out before it got too hot outside, so I was able to grab a sample and take more time photographing it. Posted 6 years ago
Fly-Speck Leaf Spot (Ophiodothella vaccinii) creates quite a stunning fungal infection in the leaves of sparkleberry (Vaccinium arboreum)! {Spotted in Georgia, USA by JungleDragon moderator, Lisa Kimmerling} #JungleDragon Posted 5 years ago
