76. LEPIOTA RHACODES Vittadini, Fung. mang. 

 1835 ; Stevenson, Brit. Fungi; Cooke, Illustr. Pl. 22. 



Pileus fleshy, at first globose then convex and explanate or 

 slightly depressed ; the flesh very thick, soft, white changing 

 immediately to saflfron-red when cut or broken ; the dermis 

 fibrillose-tomentose beneath the cuticle ; cuticle thick, smooth, 

 bay-brown, at first continuous, soon cracking and becoming re- 

 ticulate, then separating into large irregular scales, which are 

 drawn apart and persist upon the surface. Stipe tapering upward 

 from a bulbous base, thick, stout, fistulous, fibrous-stuffed, 

 smooth and glabrous, whitish ; the annulus thick, mobile, fibrous- 

 lacerate. Lamellae broad, close, whitish or pinkish, tapering 

 inward and remote from the apex of the stipe ; spores elliptic- 

 ovoid, 10-12x6-8 mic. 



Solitary or subcaespitose ; growing in rich soil in fields and 

 woods. Reported from various parts of the country from New 

 England to the Pacific coast ; but it is certainly rare. Pileus 10- 

 15 cm. in diameter; the stipe 12-20 cm. long and 1-2 cm. thick 

 above the very thick bulbous base.

 Botanical Gazette, 1879. 



Pileus fleshy, at first globose then convex and expanded; 

 the flesh thick, firm, white, deeply impressed around the apex 

 of the stipe ; the dermis white beneath the cuticle, radiately 

 fibrillose; the cuticle at first continuous, buff to pale umber, 

 soon broken up, except in the center, into irregular scales and 

 patches, which are gradually drawn apart and at length are 

 more or less deciduous. Stipe hard and firm, tapering upward 

 from a thickened base, with a narrow tubule, fibrous-stuffed, the 

 surface glabrous, buif to pale umber; annulus thick, soft, sub- 

 coriaceous, mobile, raised high upon the stipe. Lamellae rather 

 broad, ventricose, close, remote from the stipe, at first white 

 then changing to a greenish hue, at length dull green ; spores 

 in mass at first bright green, fading to dull green ; with age 

 becoming sordid, subelliptic, obliquely apiculate, 9-11x6-8 mic, 

 with a large guttule. 



Gregarious ; growing in meadows, pastures and open 

 woods ; sometimes seen grouped in large rings. Met with 

 throughout the Mississippi Valley from Michigan to the Gulf 

 States and from Pennsylvania westward to Kansas and Nebraska, 

 Pileus 10-20 cm. in diameter, the stipe 15-20 cm. in height, 1-2 

 cm. thick at the apex and 2-4 cm. thick at the base. 



h. Lcpiotae of s)iiall size; the annulus thin memhranaceous, 

 and not easily movable.
