Gymnosporangium juniperi-virginianae
Rust-colored galls form on the twigs of Eastern Red Cedar trees in times of sufficient rain. As they mature, the galls produce the tendrils of gelatinous goo which can swell until their sheer weight causes them to drop from the tree onto the ground.
At Camp Simpson, ground zero for this particular mission, the rust is found only on Eastern Red Cedar trees (Juniperus virginiana).
No harm to the affected trees has been detected.

I still think they're exciting on cedar trees!!! Apple trees . . . not so much!
I was so excited when I found one of these - until I found out what it was! :)
