 June to September. Often locally abundanl in the parks aft 

 rains. Pileus 4 to 9 cm. broad, stem 5 to 10 cm. high, 6 to 1<> 

 mm. in diameter. The pileus has the texture and color of slightly 

 soiled white kid-leather. Professor Peck in Rep. X. Y. Mus. 

 35: 160, describes the American counterpart of this spec 

 Lepiota naucinoides, and in Rep. 54: L62, he states that "by dis- 

 regarding the spore characters our plant has sometimes been re- 

 ferred to L. naucinus and sometimes to Agaricus en 

 The spores of L. naucinoides are described as " subelliptical, uni- 

 nucleate, 7.5 to 10 x 5 to 7.5 /a." Those of our plants vary from 

 elliptical (7 to 8 x 4 to 5 fi.) to subglobose (5 to 7 /*.)■ •' does nol 

 appear therefore that a distinction bused upon the shape o\ the 

 spores is applicable to them. There is an excellent figure of the 

 species in Bres. Funghi Mang. e Vel., Tav. XV. See also Morgan, 

 Journ. Myc. 13: 10, where the plant is given as L. na 



Lepiota granulosa Batsch. 



Pileus ferruginous or reddish-brown, convex then flattened, 

 obtusely umbonate, furfuraceous, granular; flesh white or ting
