 stem.

 sometimes umbonate, glabrous, dry, or in rainy weather 

 viscid, 2-3 in. broad, margin sometimes regular and spread- 

 ing, at others irregular and repand, hymenium plane. Flesh 

 yellowish, soft, unchangeable, sometimes distinctly greyish. 

 Tubes ^-^ in. long, yellow. Pores angular, large, irregular, 

 subcompound, attached to the stem and often decurrent.
