Mycologia 



melaleucum thujinum, from Warren Co., agrees best with our 

 New York City form. Tricholoma subcinereum Peck is nearly 

 allied, but is certainly distinct, having different spore characters.

Plate 49. Figure 5. X 1 



Pileus fleshy, thin, convex, papillate, becoming depressed to 

 infundibuliform, 1-5.5 cm - broad; surface fulvous, isabelline, or 

 reddish-fulvous, not fading, azonate, dry, glabrous, smooth ; mar- 

 gin involute, then spreading, sometimes flexuous : context firm, 

 fragile, whitish or tinted with isabelline or fulvous, odorless, 

 edible ; latex white, unchanging, mild or slowly acrid to bitterish ; 

 lamellae whitish or tinted with isabelline, becoming pruinose, 

 sometimes forking, close, adnate, or decurrent by a tooth, up to 

 3 mm. broad ; stipe of the same color as the pileus or paler, nearly 

 equal or tapering upwards, glabrous, or sometimes slightly pubes- 

 cent at the base, dry, stuffed, becoming hollow, 2-7 cm. long, 2-6 

 mm. thick : spores white, globular to broadly ellipsoid, echinu- 

 late, 7X8/1. 



This edible species occurs on the ground in or near woods 

 throughout the eastern United States and Europe. The above 

 description is taken from Miss Burlingham's monograph of the 

 genus Lactaria; published in volume 9, part 3, of North Amer- 

 ican Flora. 



Lepiota americana Peck 

 American Lepiota. Blushing Lepiota 



Plate 49. Figure 6. X 1 



Pileus ovoid to convex and at length expanded, umbonate, 5-15 

 cm. broad ; surface white, umbo and scales reddish-brown, the 

 entire plant becoming reddish-brown when wounded or on drying ; 

 lamellae white, free, close; spores subellipsoid, smooth, hyaline, 

 uninucleate, 7.5-10 X 5-7/*; stipe thickened below, white, hollow, 

 7-12 cm. long; veil white, forming an apical annulus. 



A conspicuous and easily recognized edible species of wide dis- 

 tribution in America, occurring in groups or clusters on rich lawns 

 or about old stumps, sawdust piles, or compost heaps from mid- 

 summer to autumn. Lepiota Morgani, a poisonous species resem- 

 bling it in shape, has green spores, causing the gills to assume a 

 green color as they mature.
