 curved, hyaline, 22-30x4-6 /i, sometimes with a short, hyaline 

 appendage at each end. 



On dead herbaceous stems, Louisiana (Langlois, 1437). 



The sporidia are for some time only 1 -septate, but finally become 

 3-5-septate and yellowish hyaline. The figs. 7-9, tab. Ill, Berlese 

 Icones, represent the sporidia very accurately.
