lawns and about dung in pastures. It is rather easily recognized 

 by its netted and wrinkled cap and the bits of veil that hang from 

 the margin. Although pronounced edible by all authorities, being 

 of nutty flavor and agreeable odor, it does not appeal to myco- 

 phagists as most edible species do. Dr. W. W. Ford recently 

 investigated this species and found an extract from it to be fatal 

 to guinea pigs; but an extract from the famous morel, Morchella 

 esculenta, was found to have a similar effect.

Pileus rather tough, convex to nearly plane, sometimes de- 

 pressed, gregarious to subcespitose, 1-5 cm. broad ; surface 

 smooth, glabrous, dry, stramineous to fulvous or bay, margin 

 involute when young ; context thin, white, of nutty taste ; lamellae 

 adnexed or sinuate, watery-white, rarely yellowish, rather close ; 

 spores ellipsoid or ovoid, smooth, hyaline, 5-7 X 4-5 p ', stipe car- 

 tilaginous, glabrous, brown and stuffed below, pale and fistulose 

 above, 2.5-7 cm - l° n g> 2- 6 mm. thick. 



Common throughout temperate regions both in woods and pas- 

 tures from spring to autumn, occurring on the ground or rarely 

 on decayed wood. An edible species of good quality, known and 

 used in many parts of the world. I have seen it exposed for 

 sale in Jalapa, Mexico, in December, specimens having been 

 brought in from the woods by the Indians. The early spring 

 form here illustrated is about half the size of the usual summer 

 and autumn form.

 spicuously imbricate-scaly, the scales more erect on the umbo; 

 context fleshy, thin, pale-yellow, pleasant to the taste ; lamellae
