The station is on or near its northern limits. Mr Shaff writes that 

 he first discovered the plant about 25 years ago. At that time and 

 for 8 years after he kept sheep and the plant did not spread much. 

 For 17 years he has kept no sheep and during this time it has 

 spread over his pastures and now occupies about five acres. 



Hypochnus tristis Karst. 



On the base of young spr.uce trees. North Elba. September. 

 The specimens are sterile and to this extent are doubtful. Pro- 

 fessor E. A. Burt, specialist in this group of fungi, decides that it 

 is probably this species.
