64 Peck : New Species of Fungi 



Pilcus 4-7 cm. broad; stem 5-; cm. long, 6-12 mm. thick. 

 Woods, Massachusetts, G. E. Francis ; Pennsylvania, Charles 



Mcllvaine. 



The central part of the pileus is sometimes a little darker than 

 the rest. The peppery or acrid taste is very distinct and remains 

 in the mouth many minutes. This and the innately fibrillosc 

 character of the pileus are distinguishing characters of the species. 

 The plants appear from September to November. 



Hygrophorus Morrisii 



Pileus thin, convex, obtuse or umbonate, covered by a viscid 

 separable pellicle, even, grayish brown or blackish brown, flesh 

 whitish ; lamellae subdistant, adnate or slightly decurrent, often 

 slightly 'eroded or uneven on the edge, white ; 'stem rather slender, 

 equal or slightly tapering downward, solid, straight or flcxuous, 

 flocculently furfuraccous, pallid or brownish ; spores elliptic or ob- 

 long, 10-12// long, 5 broad. 



Pileus 1.5-2.5 cm. broad : stem 4-6 cm. long, 3-5 mm. thick. 



Under pine trees, Waltham, Mass. November. G. E. Morris.

from it in the entire absence of pustules or papillae from the uni- 

 formly colored pilcus and in having a solid stem which, though 

 somewhat scurfy, is not rough or scabrous with black points. The 

 presence of concolorous papillae on the pileus and of black points 

 on the stem of //. piistulatus is given by Fries special emphasis in 

 his description of this species. In Icones he describes the lamellae 

 as very entire (integerrimae) which character is not applicable to 

 our plant. These differences seem to me too important to be dis- 

 regarded and I take pleasure in dedicating this interesting Ameri- 

 can species to Mr. George E. Morris, who sent me numerous 

 specimens of it in fine condition. 



Volvaria umbonata 



r 



Pilcus thin, campanulate, becoming convex or nearly plane, 

 prominently umbonate, distinctly striate, slightly viscid when 

 moist, silky when dry, white ; lamellae moderately close, free, 

 not extending beyond the margin of the pileus, pale flesh color ; 

 stem equal or slightly thickened at the base, glabrous, solid, 

 white, the ruptured membranous white volva persistent, ir- 

 regularly split or lobed on the margin and forming a shallow cup
