PILEUS 1-3 cm. broad and high, conical, unexpanded, subacute 

 at apex, often splitting-expanded, or lobed on margin, viscid when 

 moist, shining when dry, glabrous, yellow, orange or orange-red, 

 subvirgate, often stained black in age. FLESH concolor, very thin, 

 becoming black when bruised or old. GILLS almost free, ventri- 

 cose, broad, almost triangular at times, thick, rather close to sub- 

 distant, pallid to sulphur-yellow, when old black stained, trama of 

 parallel hyphae. STEM 3-9 cm. long, 2-6 mm. thick, subcylindrieal, 

 soft, dry, fibrillose-striate, usually twisted, hollow, citron to golden 

 yellow, becoming black stained with age, splitting longitudinally. 

 SPOKES broadly elliptical, 8-10 x :><;.:> micr., smooth. CYSTIDIA 

 none. BASIDIA 35-38x8 micr., slender. 



Gregarious or solitary. In low, moist, conifer or frondose woods, 

 grassy places, etc. Throughout the State. May to October. 

 (Earliest record May 8; latest October 15.) Very common. 



Easily recognized by its conical pileus and the blackening flesh. 

 The whole plant usually turns black in drying. It is not unusual 

 to find olive tints in the pileus, and the shades of yellow or orange 

 to red vary much as the plant matures or ages. After having be- 

 come rain-soaked, the whole plant is sometimes black.
