CLASSIFICATION OF AGARK 



becoming reflexed with .^ills in the usual position. The stem is 

 entirely lacking or is small and inconspicuous, usually toment 

 or villose al the point of attachment of the stem or pileus. Onh 

 a few species are known in our Bora.

PILEUS 1-7 cm. broad, shelving, scssilr or narrowed behind into 

 a short stem-like base, nearly orbicular, dimidiate or reniform, 

 coarsely hairy or tomentose on the surface, rich yellow or buff, 

 margin at firsl involute, even. FLESH soft, rather tough. GILLS 

 orangi yellow, medium broad, 'lose to subdistant, adnate, rarely 

 subdecurrent. STEM or attached base bomentose oext to the gills 

 beneath. SPORES elongated, slightly curved, •; ^ \ :: I micr., 

 smooth, /link in mass. ODOR very disagreeable when fresh. 

 TASTE becomes rather mild at length; nol desirable for tin- table. 



Gregarious or imbricately caespitose. On decaying l"u-. etc., of 

 frondose trees. Throughout the State; Marquette, Houghton, Ann 

 Arbor, etc. July-October, [nfrequent.
