This is the first uncommon myxo I have found in all my years of myxo hunting. I thought at first it was the rare Calonema aureum because they look almost identical to the naked eye. The difference is a subtle one, only found by removing some of the spore binding material or capillitium. In the case of my collected sample the capillitium is composed of simple or branched smooth elaters. Calonema has a network of sculptured branching threads. This is how the two species are identified from each other.

I burden you with this information only because the study of these myxos gives you cause sometimes to power up the microscope for some detective work. I also know that Ken would like verification of my identification. A photomicrograph will, someday soon I hope, be posted in the amateur microscopy form of this myxos spores and elaters.
