micro-shrooms
This is 3M™ Dual Lock™ "velcro". Each side is identically patterned with these "mushrooms". The advantage to this over traditional hook-and-loop fasteners is that the strong stalks provide much better hanging support for large posters. The caps interlock over each other, sticking the two pieces together. Each shroom is approximately 1.5mm tall. The red you see is from the 3M logo on the adhesive backing.
As the "undisputed king of Velcro photography", I feel obliged to periodically post some of these zoomified adhesive systems.
I took this photo with an Olympus E330 mounted to a Nikon SMZ1500 stereomicroscope using a combination of diascopic and episcopic illumination.
