Peck : New Species of Fungi 65 



at the base of the stem ; spores broadly elliptic, uninucleate, 

 variable in size, 5-7 /i long, 4-5 // broad. 



Pileus 2-3 cm. broad ; stem 5-6 cm. long, about 4 mm. 

 thick. 



Lawns and grassy places, Ohio, Lloyd. 



The species is most closely allied to Volvaria media (Schum.) 

 Fr., from which it is distinguished by Its larger spores and the 

 striate margin of the pileus. In our plant the striations some- 

 times extend to the umbo. Volvaria enicndatior (B. & C.) is de- 

 scribed as having a white umbonate pileus with striate margin, but 

 it is a much larger plant with the lamellae extending beyond the 

 margin of the pileus and with cymbiform spores \2ti long. 



Clitopilus irregularis 



Pileus thin, Irregular, sometimes eccentric, nearly plane, gla- 

 brous, reddish brown, flesh white ; lamellae rather broad, subdis- 

 tant, decurrent, whitish becoming tinged with flesh color; stem 

 short, solid or spongy within, externally fibrous, colored like the 

 pileus, usually caespitose ; spores pale flesh color, elliptic, 6-^ y. 

 iong, 3-4/^ broad. 



Pileus about 2.5 cm. broad; stem about 2.5 cm. long, 2-4 

 mm. thick. 



Manured ground, London, Canada. October. Dearness. 



Leptonia aeruginosa 



Pileus thin, convex, umbilicate or centrally depressed, striate, 

 aeruginous ; lamellae broad, subdistant, adnate, aeruginous, tinged 

 with flesh color when mature; stem slender, glabrous, hollow, 

 colored like the pileus; spores angular, 7.5-10/^ long, generally 

 containing a single large nucleus. 



Pileus 1.5-2.5 cm. broad; stem about 2.5 cm. long, 2 mm, 

 thick. 



Shaded places in woods, Oxbow river, Canada. August. 

 Dearness. 



This small mushroom is quite conspicuous by reason of its pe- 

 culiar and unusual verdigris color. This fades with age to an 

 ashy green hue. 



Flammula aliena 



Pileus thin, flexible, broadly convex, umbilicate, dry, glabrous, 

 slightly striate on the margin when old, grayish or pale grayish- 

 brown, flesh white, fibrous ; lamellae thin, subdistant, arcuate, de-
