CLASSIFICATION OF ACAKK'S :,.| 



Gregarious. On the ground, in frondose woods. August. Ann 



Alitor. 

 This seems ti> be intermediate between /. carpta Bres. and /. //>»- 



br'uia Bres. in its microscopic characters. The ho doe- not be- 



come warty nor scaly and is no1 subviscid as in the latter species. 



The same species has heeii received from .Massachusetts; it was 



sent by Simon Davis, who reports ii poisonous.

PILEUS I 8 cm. broad, large, obtusely campanulate, then broadly 

 umbonate and expanded, dry, creamy-white or tinged straw-color, 

 sometimes ochraceous-stained, silky, at length rimose and margin 

 lobod, split or recurved; FLESH while, thick, thin on margin. 

 GILLS free, rounded behind, ventricose, broader toward front, close, 

 whitish at first, then ashy-cinnamon, edge w hite-fimbriate. STF.M 

 4-S cm. long, 6-15 mm. thick, fibrous, splitting longitudinally, sub- 

 equal, striatulate t«» subsulcate, glabrescent, apex pruinate, white 

 then sordid, base often subbulbous. SPORES angular-oblong, with 

 obscure, scattered tubercles, 9-13 x .~>-7 micr., epispore reddish under 

 the microscope. CYSTIDIA fusoid, crystallate a1 apex, abundant 

 on sides and edge of gills, 60.-75x10-15 micr. <>DOR earthy. 

 TASTE mild. 



Gregarious. <>n the ground, in low, moist, frondose woods. June- 

 August. Ann Arbor. Infrequent. 



Apparently our largesl species. The spores arc inclined to be 

 more or less -innate tuberculate, i>nt the angularity is not as marked 



as in many others. The character of the surface of the pileus is 



much like /. fastigitata except in color. It appears earlier than 

 most [nocybes, and is said to be poisonous. (See Bresadola, Fung.
