On branches of various trees. 
Collected by Mrs. ~ghame ae in sabia April, 1903. The 
Species is said to be common in southe urope. The hyphe

The fungus not only grew on the clover seeds, but several 
grew on the dish on which the seeds were being tested for 
germination, long colourless hyphx connecting the different in-

The fungus corresponds with Spheronemella among the fiyaling! 
- Spored Nectrioidacea. The only genus under Nectrioidacea-Zythiee-
