Genus Lepiota 335 



the eastern plant is also provided with a bitter pellicle. It is 

 known to me from Ohio, Michigan and Oregon. 



The naming of this plant has become a slightly involved 

 matter. Morgan found it in Ohio and published it in 1906 as 

 L. Candida. Meanwhile Copeland had already used this name 

 for a Philippine species in 1905. In the North American Flora, 

 Murrill segregated it under Limacella albissima in 1914. Fi- 

 nally, the same year, Graff, in his account of Philippine fungi, 

 renamed the plant, calling it L. pulcherrima. Since then, Zeller 

 has named a red-capped Lepiota from Oregon L. pulcherrima, 

 but discovering the error, now suggests Lepiota decorata for his 

 plant.

Pileus thin, fleshy, 1-3 (5) cm. broad, at first oval to obtusely 

 subconic and then uniformly " vinaceous-brown " (Ridg.), mi- 

 nutely flocculose-fibrillose, with incurved margin, at length 

 broadly campanulate, subumbonate, dry, with long subdistant 

 striae on margin, the thin cuticle broken into numerous, ra-

 scales concolor or paler; flesh white, submcmbranous, unchang- 

 ing; gills free, rather broad, subdistant, white, becoming crisped 

 on drying, edge minutely white-flocculose; stem 2-4 cm. long, 

 1-3 (5) mm. thick, at first conic then tapering slightly upward or 

 equal, stuffed then hollow, slightly mealy or glabrous at apex, 

 white above the inferior, sheathing, thinly membranous and 

 closely appressed, " vinaceous-brown " volva, which frequently 

 disappears early leaving its upper portion on the stem as a low- 

 hung narrow annulus; odor none; spores oval or elliptic-oval, 

 9-11(12) X 5-6 (7) jji, smooth, with rosy tints; cystidia none; 

 sterile cells on edge of gills broadly saccate, obtuse, about 45 



X 12 fJL.
