Family 57. ASCOBOLACEAE 

 Rehm 1078, Lindau 188 



Apothecia typically superficial and fimicole, sessile, rarely short-stalked, scutel- 

 late to discoid, soft-fleshy or somewhat gelatinous, usually bright-colored, smooth 

 or sometimes hairy; hypothecium mostly well-developed, exciple thin or even lack- 

 ing; asci broad-cylindric or clavate, with an operculum, rarely with a slit, typically 

 projecting from the hymenium at maturity; paraphyses mostly simple; spores 

 simple, often colored, and variously sculptured. 



This family might well be included in the Pezizaceae, as has been done by 

 recent authors (cf. Seaver N. A. Cup-Fungi, 1928) but it is fairly well marked by
