abundant. Schaeffer's plant is described as having a yellow juice, and 
the pileus purplish red; in other respects they agree.

*Bol. substric'tus. (Bolt.) Tubes dirty yellow: pores minute: 
pileus dirty yellow, convex, thin: stem dirty yellow, hard, tough, 
sometimes eccentric. 
Bolt. 170. 
Tubes the longest about a quarter of an inch. Pores pale yellowish colour, 
minute, regular, angular when magnified. 
Pileus yellow brown olive, inclining to ash-colour, gently convex, thin at 
the edge, smooth, tough, leathery, one to two inches over. Flesh thin, 
white. 
Stem dusky or yellowish, white within, cylindrical or compressed, hard, 
tough, one to two inches high, thick as a goose quill. Bolton.

(1) Tubes white. 
Bol. al'bidus. Tubes white, decurrent; pores white: pileus white, 
lohed: stem whitish. 
Schoeff. 124— (Purt. 38. E.) 
Tubes decurrent, white, not perpendicular to the pileus, but sloping so much 
towards the stem as to be nearly horizontal; near the stem a quarter of 
an inch long, shorter towards the edge of the pileus. Pores white, 
angular, very irregular in shape, ragged at the end, often appearing 
sinuous, especially towards the edge of the pileus. 
Pileus white, or buff and edged with white, a fan-shaped expansion of the 
stem turning up, and wrinkled at the edge, from half to four inches over; 
often tiled. 
Stem solid, lateral, pinky white, sometimes only a knob, but generally half 
to three inches long, and one-third of an inch diameter. 
The whole plant is white, but the whiteness depends on a very fine dense 
cottony substance, which is readily abraded, and then discovers a pinky 
tinge, and when more abraded, a foxy brown. It is much perforated by 
the stems and leaves of grass, and grows on the ground, but attached to 
bits of decayed wood.
