Hi Debbie,
The black spheres are quite often seen in this genus its normal the remains of the plasmoduim after been disturbed during development. Caused by insects, wind or been poked with a stick :). You can see more extrema sample on this photo of mine http://www.flickr.com/...

Once again to Id these you would need to look at it with a microscope.

Either S. splendeus,spores purplish black…slightly warted..
or S. axifera but itis bright rust brown, with smaller smooth spores..
or S. fusca has stalk more than 1/4 total hight…spores netted..

Did they look like they were actually growing from them? Could they
be tiny beetles? That might explain the “eroding ends”…

The black spheres are not spores from Stemonitis as they are too small to see without a microscope. The brown fuzz are the spores in mass quantity.
