Synopsis of the Species of Lepiota of the North 

 Temperate Regions of Europe and America 



{Compiled in part from the literature*) 



Young plant enclosed in a glutinous universal veil i. lubricae 



Surface of pileus viscid, because of a gelatinizing, more or less separable 

 pellicle; stem dry n. viscidae 



Pileus and stem covered when in good growing condition, by mealy, floccu- 

 lose or granular particles; sometimes subscaly; veil and annulus delicate, 

 of the same texture or substance as the covering on the pileus; hence 

 the annulus is evanescent in. pruinosae 



Annulus membranous, thin but distinct, often persistent, frequently ter- 

 minating a thin, smooth, pcronate (i.e. external) layer of the stem, or 

 stem entirely naked; cuticle of the pileus at first continuous, then dif- 

 fracted-scaly except on disk iv. subclypeolariab 



Universal veil well developed, but concrete, breaking up into colored fibril- 

 lose or floccose-fibrillose scales or masses on the pileus and stem; on the 

 latter, terminating the sheath in the form of a fioccose or fibrillose, soon 

 evanescent annulus v. clypeolariae 



Universal veil composed of a thick loose fibrillose layer covering the pileus 

 and stem from the first; when drawn apart by the expansion of the 

 pileus or by the elongation of the stem, its fibers converge into con- 

 spicuous erect, or squarrose scales; the partial veil tends to be fine- 

 fibrillose or subarachnoid, often copious vi. asperae 



Plants mostly rather large; annulus well developed, membranous, sometimes 

 thick and appearing double, sometimes mobile on the stem. Pileus 

 diffracted-scaly, sometimes fibrillose, rarely glabrous _ 



VII. procerae-anntjlosae 



I. LUBRICAE 



1. Taste of pellicle not bitter 2 



1. Taste of pellicle very bitter; plant white. (See description) 



(L. Candida Morgan) . . . . L. pulcherrima Graff 



2. Spores ovoid-ellipsoid 3 



2. Spores globose or subglobose 5 



3. Pileus 5-8 cm. broad 4 



3. Pileus 2-5 cm. broad, white with fulvous umbo; gills narrow; stem 



long, slender, hollow, abruptly bulbous; spores 7.5-10 x 4-5 yu; 

 annulus membranous; in woods L. Julvodisca Pk. 



* The microscopic characters, e.g. size and shape of spores, have been 

 reported for the older species by various students of Agarics. In order to 

 show whose account of these characters is followed in the ensuing synop- 

 sis, the names of such authors are added, where necessary, after the older 

 author's name.
