Is this in Ely?

I think it's a fungus parasitizing a cherry blossom. I saw these at a friend's house recently in Ashland.

I have the same thing on my chokecherry tree.  It was ID as Taphrina Confusa, which is fungus or gull that attack flowering plants.

From a Vermont Forest Health fact sheet:

Taphrina confusa is an ascomycete gall fungus that typically forms on chokecherry (Prunus virginiana) flowers. This fungus creates large empty pockets (galls) that start out green but eventually turn yellow-brown as it matures. The galls that are formed are distorted fruit that are hollow, not containing any seed. Although this pathogen can lead to reduced fruit production, it does not contribute to large scale decline or tree mortality.
