sence of the hygrophanous character of the pileus, its smaller size 

 and more fragile nature and its different habitat lead me to keep it 

 separate. 



Velutina 



Pileus silky or streaked with innate fibrils, sometimes glabrous. 



The characters of this section, as given in Sylloge, would strictly 

 admit only species having a silky or fibrillose pileus, but inasmuch 

 as species like Hypholoma atrichum Berk, and 

 H. c a s t a n o p h y 1 1 u m Berk., of which the pileus is described 

 as glabrous, have been admitted to it, we have extended the defini- 

 tion to include glabrous species which in other respects belong here. 

 The species of the section generally have the color of the spores 

 darker than in the preceding sections. Therefore the color of the 

 mature lamellae is almost or quite black and the sjx)re print on 

 white paper appears black or nearly so. On this account the 

 species are liable at first sight to be referred to the black spored 

 series. The shape and size of the spores are in some cases im- 

 portant characters in distinguishing closely related species.

WEEPING HYPHOLOMA 

 Sylloge V, p. 1033 

 Pileus fleshy, convex, obtuse, persistently squamose with dark 

 brown or blackish hairy tufts, not hygrophanous, often irregular 

 from its crowded tufted mode of growth, brown or tawny brown, 

 flesh whitish ; lamellae moderately close, adnate or subsinuate, 

 whitish becoming purplish brown, almost black when fully mature, 

 whitish on the edge, often beaded with tearlikc drops of moisture 

 in damp weather; stem ccjual or nearly S(\ fibrillose or squamose, 

 hollow, whitish, pallid or brownish; spores purplish brown. 8-10 /t 

 long, 5-6 !>■ broad.
