was not known to occur in our state south of the Adirondack region. It has 

 recently been found in Albany county, in the swamps near the eastern base 

 of the Helderbergs. 



The cap when young is covered with a woolly coat, or veil, which 

 soon separates and forms wart-like scales, revealing the red surface of the 

 cap, which is viscid when moist. In the young plant the tubes are con- 

 cealed by a filmy membrane, but this soon separates from the margin of 

 the cap and forms a collar on the upper part of the stem. With advanc- 

 ing age the cap expands till it is broadly convex or nearly flat, and some- 

 times its color fades to yellow, either wholly or on the margin only. The 

 scales also sometimes lose their color and become paler than the cap, and 

 sometimes they are yellowish even in young specimens. The flesh is pale 

 yellow, but sometimes a little brighter next the tubes. The tubes are nearly 

 plane at first, pale yellow and with small mouths, but when mature the color 

 is a dark ochraceous, and the mouths are rather lar^e and anyular. An 

 obscure radiating structure is perceptible, as if the tubes were formed by 

 radiating gills connected by numerous transverse partitions. The stem is 

 cylindric or tapering upward, solid and firm and adorned with a thick collar 

 near the top. It is red below the collar and yellow above and within. The 

 collar is somewhat viscid and apt to become blackish when old. 



The cap is 2 to 5 inches broad ; the stem 2 to 5 inches long, 4 to 6 

 lines thick. In the raw state the flavor of the flesh is slightly disagreeable, 

 but when cooked the disagreeable flavor wholly disappears, and the species 

 may be regarded as an excellent addition to the list of edible mushrooms. 

 It is a well marked species and not liable to be confused with any other. It 

 is said to be plentiful in some places in Canada.
