cylindrical and thrice or a little more times as long as the greatest 

 wideth ; coronal processes knob-like, oval or a little longer in radial 

 direction, 67x75,^ (in one which I have measured), each bearing 

 (4?) -5-6 hair-scars arranged in elliptical manner; hypopeltal process 

 wanting ; aplanospores globose or ovoid or somewhat elliptical (in one 

 I have measured go/* in diameter) ; stipe usually much corrugated and 

 enlarged in the upper part, measuring 0.5 mm. in the thickest part.
