Stemonitis sp. sporangium
This is the Stemonitis sp. sporangium. The columella is out of the photo parallel to the top edge. The light colored surface net covers the spores which form inside. In this example, most spores have been released. Two spores are present to the left and up from centre. The surface net is held in place by the capillitium which branches from the columella. Here, the capillitium is the sider and darker colored structure compared with the surface net. The capillitium is more evident in www.flickr.com/photos/14643312@N02/20222144581 which is from the same set of sporangia.
This slime mold is also known as chocolate tube slime. Collected along the Dowagiac River. Specimens were mounted directly in PVA-LG.
