to July or August and like their larger relative attract miidi 

 attention because of their brilliant color. 



Occurring about the same time are the species of Acetahula 

 so called because of their resemblance to the ancient vinegar-cu[) 

 whatever that may have been. The two forms shown in the 

 accompanying plate {Acetahula sulcata and Acetahula vulgaris) 

 are frecjuently collected but can scarcely be said to be common. 

 The former is characterized by its fluted stem and the latter by 

 the veins which adorn the exterior of the cups. 



The saddle fungi occur in the late spring and extend through 

 until autumn. In these types the fruiting body consists of a 

 stem with a cap which is inclined to assume the form of a saddle 

 suggesting the name. The white saddle-fungus (Helvella cnspa), 

 shown on plate, is often encountered. 



The brain fungus (Gyromitra esculenia) also shown on the 

 accompanying plate is closely related to the former and is often 

 treated in the same genus. The cap in this form is convoluted 

 into brain-like folds. As the name implies the species is edible, 

 as are most of the cup-fungi. 



The orange cup {Aleuria aurantia) although often seen in the 

 spring is far more abundant in September and October. This 

 species may be easily recognized by the decidedly orange colored 

 cups reaching a diameter of one to two inches. 



The revolute cup {Peziza repanda), shown on the plate, may 

 be found during the summer and autumn on rotten logs and 

 stumps. The cups become very large often several inches in 

 diameter and flatten out, often with the margin turned back. 



Autumn Species 



While many species extend through to the autumn a number 

 are distinctly fall species. Among these is the shield-shaped 

 species (Peziza clypeata) which may be found on rotten logs from 

 September until November or until freezing weather interferes 

 with its growth. This species has been collected by the writer 

 on the same log for a number of years in succession, ahva\'s oc- 

 curring at about the same time in the autumn.
