I have specimens from Romell and Bresadola and made a col- 

 lection in Kew Gardens of a number of plants growing on a mix- 

 ture of humus and manure. Peck's specimens at Albany collected 

 by him in the Catskills agree with mine from Europe. 



In his 44th Report, Peck mentioned specimens collected near 

 Salamanca that were colored a beautiful orange-red, which he con- 

 sidered a variety of Stropharia squamosa and " apparently equiva- 

 lent to Agaricus tliraustus var. aurantiacus of Cook's Illustra- 

 tions." There are also at Albany specimens collected in Indiana 

 by J. M. Van Hook (A r o. 2558) with the following notes : 



" Pileus 6 cm. broad, orange-rufous (Ridgway), dotted with few scattered, 

 light-yellow scales, flesh white, slightly reddish immediately beneath^ cuticle, 

 not viscid (at least when dry), fleshy, flesh thin near margin, thick at center, 

 slightly umbonate. Gills becoming dark-seal-brown. Spores purple-brown, 



5- 7 x 12-14 /z. Stipe equal, reaching n cm. long, somewhat tapering at base, 

 above ring white and finely scaly upward, below ring darker colored with 

 scales color of pileus. Ring complete. Stipe stuffed." 



I have good specimens of the same variety collected at Kittan- 

 ning, Pennsylvania, by Mr. Sumstine, and at Shingletown Gap, 

 Pennsylvania, by Dr. Overholts (No. 3446). Accompanying the 

 latter are the following notes : 



" Pileus 4-8 cm. broad, convex then plane, ' zinc-orange ' or ' orange-cin- 

 namon ' (Ridgway), sometimes radiate-rugose at the center and slightly um- 

 bonate, with 2 or 3 concentric rows of white appressed separable scales near 

 the margin, these later disappearing, dry ; margin at first appendiculate with
