and abundant. Pileus 5-8 cm. in diameter; the stipe 6-10 cm. 

 in height, 3-5 mm. thick at the apex and 7-12 mm. thick below. 

 Probably confused generally with Lepiota cretacea from which 

 it seems'to differ chiefly in the pale color of the cuticle. 



61. LEPIOTA MASTOIDEA. Agaricus mastoideus 

 Fries, Syst. Myc. I. 1821, based on a figure and description 

 OF Battarra, Fungi Arim. 1755; A. (Lepiota) subremotus 

 B. & C, Ann. and Mag. N. H. 1859. 



Pileus submembranaceous, at first elliptic-ovoid then cam- 

 panulate and explanate, abruptly umbonate; the dermis radiately 

 fibrillose, plicate-sulcate around the margin, beneath the cuticle 

 snow-white ; the cuticle whitish or drab, gradually separating 

 into minute scales and warts, except upon the umbo. Stipe tap- 

 ering upward from a bulbous base, slender, fistulous, whitish, 

 subglabrous, the annulus thin, membranaceous. Lamellae rather 

 narrow, close, white, free and remote from the stipe ; spores ellip- 

 tic-ovoid, 7-9 X 5-6 mic, uniguttulate. 



Subcaespitose ; growing in rich soil about old stumps in 

 woods. New England, Sprague: Miami Valley, O., Lea, Mor- 

 gan. Pileus 6-8 cm. in diameter; the stipe 7-10 cm. in length, 

 3-4 mm. thick at the apex and 5-8 mm. thick at the base. Mr. 

 Lea's specimens were found at Waynesville ; my figures were 

 made in Dayton (1878) ; I have specimens collected about Pres- 

 ton ; so the plant is an undoubted native to this region. A. 

 (Amanita) umbonatus Schumacher, En. PI. Saellandiae, the 

 pileus furnished with brownish scales, is described by Berkeley 

 and figured by Cooke under the name Agaricus mastoideus. 

 Lepiota subremota "entirely yellow or white," Bull. Cornell Uni- 

 versity, Vol. in. No. I, should have had another name and been 

 described. 



62. LEPIOTA RUGULOSA Peck, Bull. Torr. Club, 

 1900. 



Pileus submembranaceous, broadly convex or nearly plane, 

 umbonate ; the dermis radiately fibrillose, plicate-rugulose, all 

 white, the cuticle at length breaking up into minute fibrous scales. 

 Stipe slender, nearly equal, fistulous, rufescent beneath the white 

 silkv-fibrillose cuticle ; the annulus membranaceous, subpersistent, 

 white. Lamellae narrow, close, free, white ; spores elliptic-oblong, 

 6-8x4-5 mic. 



Growing on the ground in woods. Washington, D. C. Mrs. 

 Williams; Preston, O. Pileus 1-2 cm. in diameter, the stipe 

 2-3 cm. long and 2-3 mm. thick. I find this among undetermined 

 specimens of 1896; it makes beautiful specimens; my notes do 

 not add much to Prof. Peck's description.
