CLASSIFICATION* OF AGARICS 



Blender, j h 1 1« * white, with minute hairs ;ill over the Btem. Its 

 habitat in woods Is ;i distinguishing character. Patouillard's figure 

 of V. plumulo8U8 Quel, of Europe (No. :'.:'.:'>. Tab. Analyt.) ij Bome- 

 wliai illustrative of our plant. I find the stem of V. pubescentipes 

 of thi' woods always rather Long and slender, and the cap and L;ills 

 more aarrow than in Patouillard's figure. 



570. Volvaria hypopithys Fr. 

 Hymen. Europ., 1874. 



PILEUS comco-canipanulate, 6-15 mm. high, dry, silky, whitish, 

 even on margin. FLESB thin. <;IU,S free, ascending, rather aar- 

 row, close, while then flesh -color, edge minutely crenulate. STEM 

 2-3 cm. Long, 2-3 mm. thick, solid, equal, adpressed-silky, whitish. 

 VOLVA vaginate, bilobed, tome*ntose externally, whitish. SPORES 

 5-7.5x3 I micr., smooth, elliptical. 



I have referred here ;i collection made by .Messrs. Hill and Fischer 

 of the Detroil Mycological Club, and given the description of their 

 plant. It appears to lack the pubescent stem of the typical descrip- 

 tion, but its conical-shaped cap even at maturity seems to require 

 its reference to this species or to a closely related one. The finders 

 referred it t<» V. muriinlhi because of the ,uray tinge of the pileus. 

 Patouillard's figure, however, shows the pileus of that species ex 

 panded-plane and the plain smaller. Peck i in X. Y. State Bull. 5 i 

 reports V. hypopithys for New York, but without any no 

 Our plant differs from V. umbonata Pk. in its pileus being even, qo1 

 at all viscid, although the spores are the same. Further collections 

 are oecessary to determine its true place.
