Ray Duffy labeled this cellphone pic "Odd thing in Cedar Tree," from Mill Creek Marsh late last month, and suggested it as a Tuesday Teaser.

We posted the pic as a bonus Tuesday Teaser, and here's what we learned from Mickey Rayne:

The site below offers detailed information regarding what is, in fact, the Cedar Apple Rust, as Mike G had wondered earlier. It is a gall and/or fungus disease that attacks crabapples and such.

Elaine and I had just seen it for ourselves during a photo-op walk toward the end of the daylight hours today. We are not certain that it is the same one posted as the "teaser," but it is the same thing.

(Thanks, Mickey!)
