I finally pulled out the microscope from it's holding cell on Thursday. I've been slow to process any of the pictures because, frankly, a lot of them sucked. That and I haven't identified some of them.
This is a bur I found in the dog's fur:
An unknown green thing found in my local pond. This is pretty large and pretty solid, like it's filled with sand or crystals. The blackness in the center isn't a corrupting evil, it's simply the light getting bounced around in the center.
This crazy thing is a desmid that looks like 2 jacks fused together. I've seen these before and eventually identified them, but I've forgotten. This one is take at a much higher magnification - it's over 10 times smaller than that green thing.
