Helotium 141 



This fungus was collected in Bermuda by the writer and Mr. 

 Waterston in 1938 and again in 1940. It was also collected by 

 D. H. Linder in British Guiana and Trinidad on palm leaves.

Apothecia scattered, sessile or subsessile, smooth, becoming 

 discoid, lemon-yellow, reaching a diameter of 1 mm.; hymenium 

 plane, or slightly concave; asci reaching a length of 45 60 n and 

 a diameter of 6 m. 8-spored; spores fusoid, straight, or curved, 

 1.5-2 X 6-9 ju; paraphyses very slender, slightly enlarged above. 



On stems of grasses and sedges near the base. American 

 specimen on Car ex. 



Type locality: Europe. 



Distribution: Iowa and New York; also in Europe. 



ExsiccATi: Rehm, Ascom. 1634. 



Two collections of this fungus have been seen from North 

 America. Rehm made a new variety on the Iowa material but 

 it seems to us doubtful that it should be so regarded. The type 

 of Helotium flexuosum in The New York Botanical Garden 

 seems to be identical.

 margins free, reaching a diameter of .4 mm.; hymenium entirely 

 plane from the beginning, pale-yellow; asci clavate, slightly 

 narrowed to a thick stem-like base, reaching a length of 40-55 ^t
