There are (at this writing) three microscopic images in the batch of
images released on May 4:

These don't look like blueberies, the shapes are quite irregular. These look like to my non-geologist eyes to be some sort of comglomerate. The pebbles might not be the right size for the official definition, but it the word gets my point across.

Well, they are not exactly from near Endurance. They are from Sol 91, only now put up at the Exploratorium site. Opportunity was then about 1/3 of the way between Fram Crater and Endurance. JPL has them here (http://marsrovers.jpl.nasa.gov/gallery/all/opportunity_m091.html).

They were probably taken during IDD operations pictured here (http://marsrovers.jpl.nasa.gov/gallery/all/1/f/091/1F136268357EDN1500P1111L0M1.HTML), in or around this scuff (http://marsrovers.jpl.nasa.gov/gallery/all/1/p/091/1P136275898EFF1502P2551L2M1.HTML).

Although the scale is probably not right, the last time I saw something Terran that looked like that was in a stream bed. Perhaps if I had had a magnifier, the sand surrounding the water-shaped stones would have resembled what's in the Sol 91 images.

That is slightly reminiscent of the pebbly soil that Spirit saw in Gusev on Sol 52 (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/052/2M130974259EFF1100P2953M2M1.HTML), Sol 45 (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/045/2M130356321EFF0800P2943M2M1.HTML), Sol 41 (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/041/2M130001298EFF0506P2943M2M1.HTML), and Sol 39 (http://marsrovers.jpl.nasa.gov/gallery/all/2/m/039/2M129820344EFF0400P2943M2M1.HTML).
