Porphyrosporse 



Quantities of var. leiocephalus grow in the West Virginia forests on Hyphoioma. 

 stumps and on the ground from decaying roots. i'/4 in. is the limit of 

 its width. Its frequent and dense clusters, its tenderness and deli- 

 cacy of flavor make it a favorite. 



H. aggrega'tum Pk. aggrego, to grow together. Densely cespitose. 

 PileilS thin, convex or subcampanulate, grayish-white, obscurely spotted 

 with appressed brownish fibrils. Lamella? subdistant, rounded behind, 

 nearly free, at first whitish, then brown or blackish-brown with a whitish 

 edge. Stem rather long, hollow, somewhat woolly or fibrillose, white. 

 Spores brown, elliptical, 8x4-5^. 



PileilS about I in. broad. Stem 2-3 in. long, 1.5-2 lines thick. 



At the base of trees and stumps in woods. Alcove. September. 



The cespitose habit and obscurely spotted grayish-white pileus are 

 marked features of this species. From H. silvestre the species may be 

 distinguished by its smaller size, adnexed or nearly free lamellae which 

 have no rosy tint, and by its very cespitose mode of growth. Peck,

Mt. Gretna, Pa., about trees and stumps. September to November, 

 1898-1899. Mcllvaine. Not reported elsewhere. 



The caps are oyster-color. Amateurs accustomed to the gayer colors 

 of the autumnal Hypholomas will not suspect this of belonging to the 

 genus, until the color of the spores is obtained. 



The caps are fine. 



H. laclirymabim'dum Fr. lachryma, a tear. Pileus 2-3 in. broad, 

 whitish when young, then dingy-brown, becoming pale around the mar- 

 gin, truly fleshy but not compact, convex, obtuse, scaly with hairs, the 

 innate scales darker. Flesh white. Stem 2 in. long, 3-4 lines thick, 

 hollow, somewhat thickened at the base, scaly with fibrils, becoming 

 brownish-whitish. Veil separate, clothed with fibers, hanging from the 

 pileus, white. Gills adnate, crowded, 3 lines broad, whitish then 

 brownish-purple, edge whitish and distilling drops in wet weather. 



Spores brownish-purple. From mutual pressure the caps are often 

 irregular. Very cespitose, firm. Fries. 



Spores brownish-purple, 9x4^ Massee. 



On ground and on trunks. Truly cespitose. Smaller than H. velu-
