Family 55. PEZIZACEAE

Apothecia typically superficial and terrestrial, sometimes erumpent, rarely phytog- 

 cnous, urn-shaped, cupulate or disciform, stalked or sessile, fleshy or fleshy-waxy, 

 bright-colored to brown, rarely black, frequently hairy, setose or ciliate; hypothecium 

 usually well-developed, epithecium mostly lacking, exciple present and not specially 

 diflferentiated, rarely lacking; asci typically cylindric, 8-spored, regularly opening 

 by an operculum or lid, rarely by a slit; paraphyses present, filiform as a rule; 

 spores simple, mostly hyaline. 



The fleshy texture and terrestrial habit serve to distinguish this family from 

 the Helotiaceae, though the genus Pitya is more or less intermediate between the 

 two. The transition to the Helvellaceae is almost imperceptible, several genera 

 fitting almost equally well in either, and this is likewise true of the relationship to 

 the Ascobolaceae. As with the Bulgariaceae in particular, the texture of the cup 

 renders the protection of the exciple less necessary, and this feature becomes obso- 

 lete in a few genera, properly included in the Agyriaceae. 



The sculpturing of the spore-wall is a feature in several genera, ranging from 

 fine points to warts, reticulations or striae. With the exception of Aleuria and its 

 relatives, the range of variation within the genera concerned is too great to warrant 

 its use, and Aleuria itself is retained largely because of custom.
