608 THE AGARICACEAE OF MICHIGAN 



by the ashy-colored pulverulence on cap and stem, and the median, 

 pendant annulus. The main color of the pileus varies from umber- 

 brown to drab, with an obscure tinge of lilac or purplish. It is an 

 autumnal Amanita of the conifer forests. 



648. Amanita recutita Fr. var. (Suspected) 



E] Lcrisis, 1836-38. 



[llustration : Michael, Fiihrer f. Pilzfreunde, Vol. 3. No. 124. 



PILEUS 5-8 cm. broad, convex-plane, dry, grayish, brown on disk, 

 disk dotted with patch-like whitish scales, striate on margin. 

 FLESH rather thin, white. GILLS free but with decurrent line, 

 rather narrow, close, white or whitish, trama divergent. STEM 8-9 

 cm. Long, slender, 7-10 mm. thick, silky, white, equal above the small 

 rounded bulb. ANNULUS membranous, thin, snbpersistent, dis- 

 tant .narrow, whitish. VOLVA sheathing but short, truncate, thick- 

 ish. extending above bulb, whitish. SPORES broadly elliptical, 

 oval to snbpyriform. 11-13x7-9 micr.,' variable in shape, smooth, 

 white. BASIDIA 4045x10 micr., attenuated downward, 4-spored. 



ODOR none. 



On sandy soil, coniferous region, under thickets. New Richmond. 



September. Rare. 



This species is distinct from .4. porphyria and A. tomentella, 

 which it imitates in size and coloring, and by its large spores. It 

 differs also from A. porphyria in the mode of breaking of the uni- 

 versal veil, the greater part of which remains at the base of the stem 

 in the form of a thimble. The spores agree with the species as 

 known to Boudier. (Soc. Myc. d. France, Bull. 18, p. 259.) The 

 st nations of our plants extend halfway to the center of the cap and 

 this seems to be an aberrant feature, although the descriptions by 

 European authors are not very full.
