Nov. 1906 ] North American Species of Lepiota 24 & 
i mm. thick. “A small but extremely elegant species;” it is de¬ 
sirable that the spores be known. 
49. LEPIOTA RUBROTINCTA Peck, 35 N. Y. Rep. 
1882. Mastocephalus carneo-annulatus Clements, Bot. 
Neb. IV. 1896. Lepiota Erythrella Spegazzini, Fungi, Apg. 
1899. Sylloge XVI. 10. 
Pileus fleshy, ovoid then campanulate and explanate, sub- 
umbonate; the flesh thin, white; the dermis radiately fibrillose; 
the cuticle at first continuous, orange-red to red and rufous or 
darker in the center, at length rimulose-sulcate and becoming 
scaly nearly to the umbo. Stipe tapering upward from a clavate 
base, fistulous, pure white, the cuticle silky-fibrillose or quite 
smooth; annulus a thin persistent membranaceous band, the 
border often colored as the pileus. Lamellae rather narrow, 
close, ventricose, white, free and sub-remote; spores elliptic- 
oblong, obliquely apiculate, 7-10x4-6 mic., uni-guttulate. 
Growing on the ground among old leaves in woods, New 
England westward to Kansas and Nebraska. Pileus 3-7 cm. in 
diameter; the stipe 4-10 cm. long, 3-5 mm. thick at the apex and 
5-10 mm. thick at the base. Spegazzini gives a most elaborate 
account of this species in all its forms; the form e. virescens 
however, seems to me distinct enough to constitute a species. 
50. LEPIOTA INCARNATA, Mastocephalus incar- 
natus Clements, Bot. Neb. IV. 1896. 
Pileus fleshy, conical, at length campanulate, rarely convex; 
the flesh very thin, white; the dermis radiately fibrillose, striate 
around the margin, pale incarnate beneath the darker cuticle, 
which at length separates into numerous small scales, the umbo 
becoming black. Stipe slender, equal, fibrous-stuffed, glabrous, 
rarely silky, pallid or pinkish; the annulus thin, membranaceous, 
persistent. Lamellae subdistant, white, free and remote; spores 
elliptic-ovoid, apiculate, 5-6 x 3 mic. uniguttulate. 
Growing on the ground among old leaves in woods. Ne¬ 
braska, Clements. Pileus 2-4 cm. in diameter, the stipe 3-6 cm. 
long and 2-5 mm. thick. 
51. LEPIOTA VIRESCENS, Lepiota erythrella e. 
virescens Spegazzini, Fungi Arg. 1899. Lepiota caeru- 
lescens Peck, Bull. Torr. Club, 1899. 
Pileus fleshy, ovoid then campanulate and explanate, sub- 
umbonate; the flesh very thin, at first white, the whole plant ex¬ 
hibiting tints of red, green and blue when handled; the dermis 
radiately fibrillose, becoming rimulose-sulcate nearly to the cen¬ 
ter; the cuticle at first testaceous to umber, soon separating into 
minute reflexed scales. Stipe tapering upward from a clavate
