Yes, I've seen it on my olallieberries.  I've never seen it before. We have had several unseasonable heatwaves including two as early as April.  My yard suffered a lot of sunburn despite my going out and handwatering when I knew the heatwaves were predicted.  While the watering staved off some damage, I think the rest seemed unavoidable because the plants just couldn't take the shock of going from temps in the 60s to temps in the 80s with no in-between.

If there's more infomation on what causes the white drupelets, I'd be interested in hearing it.

We're started picking Arapaho blackberries now, and a high percentage have
several white (or tan) drupelets per berry.  The white drupelets shrivel and
die and make the berries unappealing.  There doesn't seem to be a clear
consensus among experts as to the cause of this problem (i.e. sunburn,
temperature related, genetic, etc.)  I was wondering if anyone else is
seeing it this year.
