So AGARICINI. 



C. I^loydii. N. Sp. 



Pileus, very thin, ovate at first, then campanulate, ex- 

 panded, sulcate pHcate. 



Gills, Hght at first, at length dark. 

 Stem, fistulous, tender. 



C. G. L/loyd discovered this new species south of Trexlertown, Pa., 

 1898. It comes near C. ephemerus, but with characters sufi5ciently 

 different to make it a good species. 



Genus XXX. CORTINARIUS. 



This genus received the name from cortina^ a spider-web 

 veil, which is the principal character of the genus. It requires 

 a young specimen for its detection, for the veil is ver}'- delicate. 

 Parts of it are thickened, which are attached to the margin of 

 pileus and stem. The hymenophore and the gills are continu- 

 ous with the stem. Gills persistent, dry, changing color, last 

 pulverulent, with rusty spores, which drop slowly. Trama 

 fibrillose. Spores rusty or cla}'- color. Growing on the ground. 



The veil and gills are the principal marks of distinction. 

 They are very different in appearance in the different stages of 

 growths, moist or dry. It is necessary to examine them in the 

 different stages. 



The genus is divided into six tribes or subgenera, which 

 might be elevated to the rank of genus, the same as the sub- 

 genera of the genus Agaricus. They are : 



Tribe i. Phlegmacium or Schleimkopf, which has the 

 pileus viscous, stem dry, veil spider-web. 



Tribe 2. Myxacium (mucus). Whole plant is viscous, 

 pileus and stem. The stem is thickly coated with gluten, but 

 only when it is wet or moist ; when dry it is glossy. The 

 Germans call it the Schleimfuss pilze.
