 of which it is the conidial form.

 erect, septate, simple, rarely branched near the base, up to 

 150 p. long, repeatedly dividing near the apex, in a dicho-

On decaying Poria vaporaria. 



The habit is that of ClonostacJiys araucaria, Cda. It is 

 worth inquiry whether this may not be a state of Hypocrea 

 farinosa. (B. & Br.)
