OCHRE-SPORED AGARICS. 157 



touched. In the young plants the color of the delicate hairy surface 

 is deeper, often phlox-purple, the color becoming thinner as the cap 

 expands. 



The gills are notched (sinuate) at the stem, or adnate, sometimes 

 slightly decurrent, crowded. Before exposure by the rupture of the 

 veil they are cream-buff in color, then taking on darker shades, drab 

 to hair brown or sepia with a purple tinge. The stem is yellowish, 

 nearly or quite the color of the cap, often with a purplish tinge at 

 the base. It is covered with numerous small punctate scales of the 

 same color, or sulphur yellow above where they are more crowded 

 and larger. The scales do not extend on the stem above the point 

 where the veil is attached. The stem is slightly striate above the 

 attachment of the veil. It is somewhat tough and cartilaginous, solid, 

 or in age stuffed, or nearly hollow. The veil is floccose and quite 

 thick when the plant is young. It is scaly on the under side, 

 clinging to the margin of the pileus in triangular remnants, appearing 

 like a crown. The color of the veil and of its remnants is the same 

 as the color of the scales of the cap. 



The spores in mass are light brown, and when fresh with a slight 

 purple tinge. (The color of the spores on white paper is near wal- 

 nut brown or hair brown of Ridgeway's colors.) Under the micro- 

 scope they are yellowish, oval or short oblong, often inequilateral, 

 6-8 x 4-5 n. 



Figure 151 is from plants (No. 4016, C. U. herbarium) collected 

 at Blowing Rock, N. C., September, 1899, on a fallen maple 

 log. The plants sometimes occur singly. It has been collected at 

 Ithaca, N. Y., and was first described from plants collected at 

 Waynesville, Ohio. 



HI a m mil I a sapinea Fr., is a common plant growing on dead conifer- 

 ous wood. It is dull yellow, the pileus 1-4 cm. in diameter, and 

 with numerous small scales. 



HEBELOMA Fr. 



In Hebeloma the gills are either squarely set against the stem 

 (adnate) or they are notched (sinuate), and the spores are clay-col- 

 ored. The edge of the gills is usually whitish, the surface clay-col- 

 ored. The veil is only seen in the young stage, and then is very 

 delicate and fibrillose. The stem is fleshy and fibrous, and some- 



/ 



what mealy at the apex. The genus corresponds with Tricholoma 

 of the white-spored agarics. All the species are regarded as unwhole- 

 some, and some are considered poisonous. The species largely 

 occur during the autumn. Few have been studied in America.
