HELOTIACEAE 



135 



waxy-fleshy, typically bright-colored, frequently setose or hairy; hypothecium usually 

 well-developed, epithecium only rarely so, exciple prosenchymic and bright-colored 

 as a rule; asci mostly cylindric and 8-spored, paraphyses filiform or lance-pointed; 

 spores typically hyaline. 



This family is distinguished from the related MoUisiaceae by the bright-colored 

 prosenchymic exciple and the thick hypothecium. The line between it and the 

 Pezizaceae is less marked, but the small waxy apothecia of phytogenous habit 

 serve to separate them more or less clearly.
