Jan. 190 j] ]Si or th American Species of Lepiota 13 



87. LEPIOTA PELIDNA, A. (Lepiota) pelidnus B. & 

 M. : Syll. Crypt. 1856. 



Pileus fleshy, ovoid then convex and expanded ; the flesh 

 thick, white, rufescent ; the dermis thick, furfuraceous-rugose, 

 greenish-Hvid in color; the veil continuous with the dermis and 

 of similar substance, at maturity lacerate, the fragments depend- 

 ent from the margin of the pileus. Stipe arising from a thick 

 bulbous base, solid, elongated, furfuraceous-scaly and colored as 

 the pileus. Lamellae narrow, white or pinkish, rufous when 

 dried, remote from the dilated apex of the stipe and there attached 

 by a very short tooth ; spores globose and oblong, 10 mic. in 

 length. 



Growing on fallen trunks, Columbus, O., Sullxvant. Pileus 

 7-9 cm. in diameter; the stipe 11-15 cm. long, in the middle 1.5-2 

 cm. thick, the bulbous base 3-4 cm. in diameter. The species is 

 remarkably distinguished by the greenish-livid color of the pileus 

 and stipe, the color of Russula virescens. 



88. LEPIOTA DRYMONIA Morgan sp. nov. Illus- 

 tration IN HERBARIUM. 



Pileus fleshy, subglobose then convex and expanded ; the 

 flesh thick, white ; the dermis thick, drab to pale umber, soon 

 breaking up into reflexed, squarrose scales, which are gradually 

 drawn apart and scattered over the white surface. Stipe stout, 

 solid, tapering upward from a thick base, squarrose with reflexed 

 scales, colored as on the pileus ; the veil thin, white mem- 

 branaceous, lacerate, the outer fragments appendiculate. La- 

 mellae broad, close, white, free ; spores . 



Growing on the ground among old leaves in woods. Pom- 

 fret, Vt., Morgan. Pileus 8-10 cm. in diameter; the stipe 10-14 

 cm. long, 12-16 mm. thick at the apex, 3-4 cm. thick at the base. 

 This is certainly an elegant species of the type of Lepiota Vitta- 

 dini, but unfortunately I failed to bring away my specimens and 

 get the spore measurements. 



XL LENTICULARES. Dermis of the pileus growing 

 uniformly zvith the expansion of the latter and maintaining a 

 smooth, unbroken surface, but coated with a thin, viscid epi- 

 dermal layer. Stipe solid or stuffed; the veil large mem- 

 branaceous. 



A tribe consisting of a few species of large Agarics, most 

 of them formerly referred to Amanita. Karsten and Gillet 

 transfer the species of Erie's fourth tribe to Lepiota. Costantin 

 and Dufour describe Lepiota Persoonii Fr., L. lenticularis Lasch 

 and L. arida Fr. all with "chapeau visqueux."
