These are Heritage from the Fall 2013 crop. They were in their first real productive year. I did not see this issue much, if at all, in the Summer crop, and did not see it at all in the Summer with the Latham I have.
This does not look to me like a rust or the like, but undeveloped 'nodules' on the berries. Could it be lack of a nutrient? Too much or too little water? (I can't water -- just rely on rainfall.)
This looks like rust to me (what's called late leaf rust is my guess) although I'd need to see a sample of the fruit to verify. This is an alternating rust. The alternate host is white spruce. We don't have a fact sheet on this, but there is one through Ohio State University at http://ohioline.osu.edu/hyg-fact/3000/pdf/HYG_3210_08.pdf.
Hope this helps. Let me know if you have questions.
