Apothecia gregarious or cespitose, sessile, at first globose, 

 gradually expanding, finally reaching a diameter of 5-6 cm. 

 though often smaller, shallow, cup-shaped and usually regular in 

 form when young, becoming irregular and often variously con- 

 torted with age or from mutual pressure, occasionally discoid 

 and rarely one-sided and Otidea-\\\ie, externally whitish, pruinose; 

 hymenium concave or almost plane, bright-orange, the color 

 fading in dried specimens; asci cylindric or subcylindric, reaching 

 a length of 175-250 ^ and a diameter of 12-15 m; spores 1-seriate, 

 usually obliquely arranged in the ascus, the ends often over- 

 lapping, at first smooth and usually containing two large oil- 

 drops, finally becoming sculptured, 9-10 X 18-22 /.t; spore- 

 sculpturing taking the form of reticulations which are regular in 

 form and shallow, except at the ends of the spore where the 

 ridges project, giving rise to apiculi; paraphyses strongly and 

 rather abruptly enlarged at their apices, the ends often sub- 

 globose, reaching a diameter of 7-8 jx, filled with orange granules. 



On damp soil in woods and open places, occasionally on lawns 

 but more often on naked clayey soil.
