lid; spores oblong-fusiform, ochraceous-brown tinged with 
green, .0005 to .0006 in. long, .o002 broad. 
Var. albzpes. Stem whitish, wholly reticulated, the reticu- 
lations coarser near the base. 
Var. pallidipes. Stem pallid, slightly furfuraceous, even 
or obscurely reticulated toward the base, distinctly reticu- 
lated above. 
Var. Zenuzpes. Stem slender, elongated. 
This species is closely related to B. edulzs, from which it 
is easily separated by its squamulose-tomentose pileus and 
less free tubes. It is very variable in the character of the 
stem. In drying, the pileus often becomes yellowish. The 
ochraceous tube mouths indicate an approach to the Luridi.
