Although one of my reference guides considers Dictydium cancellatum to be a common myxomycete this is my first encounter with it. I was most fortunate again to capture it upon it’s emergence. It’s appearance at that stage bears no resemblance to its spore release phase which can be seen if you like in the my post of this subject in the Photography through the Microscope gallery. Image 2 shows the result hours later of the sporangia having become stalked. Further changes will transform the ball shaped portion into the distinctive cage like structure of the sporangium that makes identification easier than most others.

These are really small Ken and easily overlooked. I actually found them scanning a log for remnants of stemonitis. If you would be so kind, take another look at image #2 in the upper right corner. There is a small bush or coral like entity there that I have been trying to get a good image of at much higher magnifications. Have you ever seen one? It appears to be fungal in nature with spore capsules at the tips that resemble pharmacutical capsules.
Thanks lauriek, people always prefer the fresh fruiting bodies. It was a bear to light and I have to work fast with these specimens as they deteriorate in less tha 10 minutes.
