Lepiota farinosa, n. .sp. 



Pileus thin, rather tough, flexible, at first globose or ovate, then 

 campanulate or convex, covered with a soft dense white floccose-fari- 

 nose veil which soon ruptures, forming irregular, easily detersible 

 scales, more persistent and sometimes brownish on the disk, flesh 

 white, unchangeable; lamellae close, free, white, minutely floccose on 

 the edge; stem equal or slightly tapering upward, somewhat thickened 

 at the base, slightly farinose, often becoming glabrous, hollow or with 

 a cottony pith above, solid at the base, white, pallid or straw-colored, 

 the annulus lacerated, somewhat appendiculate on the margin of the 

 pileus, evanescent; spores subovate, .0004 to .0005 in. long, .0003 

 broad. Pileus 1.5 to 2.5 in. bi-oad; stem 2 to 3 in. long, 2 to 4 lines 

 thick. 



Mushroom beds in a conservatory. Boston, Mass. March. Com- 

 municated by E. J. Forster. 



This species is related to L. cepcestipes, from which it may be distin- 

 guished by its pileus which is not plicate on the margin and by its 

 larger spores. It is edible. It is very distinct from Amanita farinosa. 



Pholiota aeruginosa, n. sp. 



Pileus hemispherical or convex, obtuse, glabrous, greenish, becoming 

 tinged with brown, sometimes slightly rimose-areolate, flesh pale or 

 whitish, tinged with green; lamellae broad, rounded behind, adnexed, 

 pale ochraceous when young, becoming bright ferruginous or orange 

 ferruginous; stem solid, glabrous or slightly fibrillose, somewhat sul- 

 cate-striate, colored like the pileus, sometimes curved, flexuous or 

 csespitose; annulus slight, lacerated, evanescent; spores copious, 

 bright ferruginous, subelliptical, .0003 to .00035 in. long, .00016 to 

 .0002 broad. 



Pileus .5 to 2 in. broad; stem 1 to 1.5 in. long, 2 to 3 lines thick. 



Decaying railroad ties of oak. Trexlertown, Pennsylvania. October. 

 William Herbst. 



This species is remarkable for its greenish color and for its abund- 

 ant bright colored spores, which sometimes fall upon and completely 

 cover the surface of tha lower prlei in a tuft. It is easily distin- 

 guished from Stropharia ceriiginosa by its solid stem, dry pileus and 

 bright ferruginous lamellsR and spores. It belongs to the Section 

 -3Egeritini. 



Phellorina Californica, n. sp. 



Peridium subobconic, thin, even or slightly rimose-areolate, 9 to 12 

 lines high, 12 to 18 lines broad at the top, whitish becoming rusty- 

 ochraceous, the vertex convex; stem nearly equal, solid but softer
