§ i. ANNULI INFERI. THE VEIL IN THIS SEC¬ 
TION HAS A TWO-FOLD ORIGIN; IT IS A CONTINUA¬ 
TION OF THE OUTERMOST ROW OF CELLS OF THE 
STIPE WHICH HAS GROWN FOR SOME TIME WITH 
THE STIPE BY INTERCALARY GROWTH AND PASSES 
INTO THE MARGIN OF THE PILEDS; AND CON¬ 
VERSELY IT IS A CONTINUATION OF THE OUTER¬ 
MOST HYPHAE OF THE PILEUS PASSING INTO THE 
SURFACE OF THE STIPE. THE SEPARATION TAKES 
PLACE AT THE MARGIN OF THE PILEUS, THE VEIL 
REMAINS ATTACHED TO THE STIPE AS A RING OR 
AS A SHEATH RUNNING DOWN ITS SURFACE OR 
SOMETIMES PORTIONS OF IT FORM A FRINGE OR 
APPENDAGE TO THE MARGIN OF THE PILEUS. 
I. MESOMORPHAE. Dermis of the pileus entire, the 
surface of both pileus and stipe smooth and glabrous; the veil 
annulate, often evanescent. 
A tribe of small Agarics. More than a dozen species are 
enumerated in the Sylloge Fungorum. 
1. LEPIOTA MESOMORPHA Bulliard, Herb. Fr. 1791. 
Pileus a little fleshy, campanulate then expanded, dry, 
smooth and glabrous, whitish, ochraceous or yellowish. Stipe 
short, slender, hollow, smooth and glabrous, concolorous with the 
pileus ; the annulus more or less persistent. Lamellae rather nar¬ 
row, white, free, approximate; spores elliptic-ovoid, 4-5 x 3 mic. 
Growing on the ground in woods. Preston, O. Pileus about 
2 cm. in diameter, the stipe 5-7 cm. long and about 2 mm. thick. 
2. LEPIOTA RUFIPES Morgan sp. nov. 
Pileus a little fleshy, convex, smooth and glabrous, white. 
Stipe slender, smooth and glabrous, rufescent, paler at the 
summit; the annulus evanescent. Lamellae broad, close, white, 
free, approximate; spores oblong, 4-5 x 3 mic. 
Growing on the ground in woods among old leaves; Pres¬ 
ton, O. Pileus about a centimeter in diameter, the stipe 2-3 
cm. long. 
II. EUCONIATI. Dermis of the pileus not lacerate, but 
the surface pruinose, finely pulverulent or minutely fur fur ace oils; 
the investment of the stipe usually similar to that of the pileus; 
the veil often afpendiculate. 
These are mostly small Agarics easily recognized by the 
powdery surface of the pileus. 
A. STIPE GLABROUS. 
3. LEPIOTA CRISTATELLA Peck, 31st N. Y. Rep. 1878. 
Pileus thin, convex, subumbonate, minutely mealy especially 
on the margin, white, the disk slightly tinged with pink; the 
Veil lacerate, leaving fragments on the margin or evanescent.
