Plates 1, 9 and 33 



Caps usually irregular, often cespitose, 0.5-2.3 cm, broad, rounded 

 or nearly plane to depressed in center, usually slightly unbilicate, 

 nearly smooth or minutely fibrous roughened, hygrophanous, and, 

 when water-soaked, of a dull fleshy-brick color with a distinctly 

 deei)er-colored line over each gill (striatulate) ; when dry ]iale fleshy 

 buff and not striatulate or very faintly so. Flesh colored like the 

 surface, brittle, very thin and translucent, only one-third mm. thick 

 near stem ; taste rather nutty. 



Gills broadl}' adnate. usually sinuate, sometimes squarely attached, 

 very slightly decurrent, distant, thick, irregular, the margin blunt, 

 deep flesh color and distinctly poAvdered with the white spores. 



Stem 1.2-3.5 cm. long, 1-2 mm. thick, equal, often twisted and 

 bent, sometimes flattened ; surface pruinose, flesh tough, fibrous, a 

 small hollow, color of cap, the base often somewhat swollen and at 

 times white with mycelium. 



Spores white, spherical, echinulate, 7.4-10.3/x, (up to 11/i,, count- 

 ing the .spines) usually about 9.2/x in diameter. Basidia (of No. 

 5121) 9.7-12.5 X 30-37/a with 4 long, curved sterigmata. 



Frequent in damp depressions in woods and along wet ditches. 

 The spores of our plant are smaller than the dimensions given by 

 Peck, but they are distinctly echinulate and also very variable in 

 size in the same plant. The striatulate cap, small size, irregular 

 .shape, thick distant and leathery gills, large spores and swampy 

 habitat would indicate lliis species. Patouillard describes and fig- 

 ures the basidia as two-spored (see below). They have not been so in 

 the plants we have examined.
