Genus 4. STEMONITIS. Gled. 
Sporangia cylindrical, shortly stipitate, gregarious ; hollow 
stem lengthened in the centre, attenuated upwards as a columella; 
capillitium formed of numerous threads radiating from the colu- 
mella, combined into a loose net, the ultimate branches united into 
a network at the surface, parallel to the walls of the sporangium, 
extended and combined by the help of very short, delicate perpen- 
dicular (to the net) ends.
