COLUMELLA: ending below the summit of the sporangium.
CAPILLITIUM: with a smooth and usually close surface-net, connected with the columella by few stout branches, and composed of rather firm threads bounding rounded meshes, which are usually small although varying in size.
NOTES: Off all the Stemonitis this is the most common. As with many members of this genus the plasmodium is able to find its way through decaying wood this enables fruiting on relatively dry logs after merging from within the log were it is still most.
