CLASSIFICATION OF AGARK 



of C dolobratus Fr. as figured i»> Cooke (HI., PL Bll) in 



Bhape of stem and the brown color; further re the margin '>f the 



pileus of thai species is al ftrsl incurved. Neither the pil< 

 our plant aor thai occuring a1 Stockhobn had b trulj ferruj 

 Hi- testaceous color when moist. 



446. Cortinarius sp. 



PILEUS 2-8 cm. broad, conico-campanulate, subexpanded e;la

its somewhat cone-shaped, rather acute pileus, broad gills and bul 

 bous to clavate stem. G. candelaris Fr. is half-waj between the two 

 in having ;i conic-campanulate pileus and a radicating stem and the 

 spores, according to Ricken, measure '.Ml \ I.", micr. Pound in 

 quantity, bul al] with clavate-bulbous stems. Specimens ■•!' I 

 candelaris from Bresadola had spores measuring 6 7.5 i 5 micr.
