 cylindrical; sporidia clavate-cylindrical, numerously septate, 

 constricted at the septa, .05 X .0025— .004 mm., paraphyses 

 filiform . 



On Lwpinus arboreus. No. 3164. Externally similar to

 each half, reddish brown. .06— .09 X .013— .02 mm. 



On dead stems of Pentstemon breviforns No. 3236. 



The sporidia are nearly as large as those of Ostreichnion 

 Americanum, Duby, but it is a true Triblidium.

Resembling H. pulicare, Pass., but sporidia altogether 

 unlike.
