 ophore distinct from the stem. The Volvarias are as it were 

 Amanitas with rosy spores, but they 

 are more nearly related to the Plutei 

 and the Psalliotas. Gills rounded be-

Volvaria corresponds with Ama- 

 nita. The species appear early in the 

 year. They grow chiefly on rotten 

 wood or in rich mould or manured 

 ground; hence they are more frequent 

 in gardens, hothouses, c., than in 

 woods. Some are said to be edible, 

 but they soon acquire a disagreeable 

 taste from the rapidity with which 

 they decay.

 broad, wholly -white, fleshy, soft, at first globose, soon campan- 

 ulate, at length convex, somewhat umbonate, everywhere silky- 

 or, when older, sqiiamuloso-villoits, more rarely becoming smooth 

 at the vertex; flesh not thick, white. Stem 7.5-15 cent. (3-6 in.) 

 long, 12 mm. (}4 in.) thick or more at the base, solid, equally 

 attenuated from the base to the apex, even, smooth, white. Vol-
