and a diameter of 9-11.5 m, 8-spored; spores 2-seriate above, 

 1 -seriate below, ellipsoid to ovoid, slightly curved, or flattened on 

 one side, attenuated toward the ends, sometimes more or less 

 slipper-shaped, 3.5-4 X 11-17 m; paraphyses long, straight, 

 simple, or rarely once branched. 



On much decayed leaves of various trees and on old pods of 

 Rohinia Pseudo-acacia.

38. Helotium simulatum (Ellis) Seaver, comb. nov. 



Peziza simulata Ellis, Bull. Torrey Club 8: 73. 1881. 

 Phialea simulata Sacc. Syll. Fung. 8: 254. 1 889. 



Apothecia gregarious, stipitate, dull watery-white, reaching a 

 diameter of 3 mm.; hymenium plane, or nearly so, slightly 

 umbilicate, becoming concave in drying; stem about 3 mm. long, 

 contracted and darker below; asci cylindric, 8-spored; spores 

 ellipsoid, hyaline, 12 y. long. 



On decaying maple, Acer, leaves lying on the ground. 



Type locality: Newfield, New Jersey. 



Distribution: Known only from the type locality. 



Ellis states: "The stipe arises directly from the leaf, mostly 

 from the veinlets, and is not attached to any sclerotium. When 

 young the whole plant is milk white."
