POLYPORACEiE 
105 
with red. Common in ant. in woods and pastures. The var. 
nanus ( P . 1 in.) differs in the flesh, becoming red when cut, 
and in the elongated sinuous openings of the tubes. The 
var. versicolor (P. ij in.) may be at once recognised by the 
beautiful rose-pink pileus. 
B. radicans (radix, root) differs from chrysenteron chiefly in 
the permanently incurved margin of the pileus, flesh not 
reddening, smaller pores, and stouter stem tapering down¬ 
wards into a rooting base. 
B. subtomentosus (from the somewhat tomentose pileus), 
“ Yellow-crack Bolet.” Plate XXXIV. 7. 
Somewhat resembling B. chrysenteron , but known by the 
absence of red under the tomentum ; hence the cracks are 
yellowish, never red. Common in woods in ant.; sometimes 
growing from the interior of beech-nuts. In the var. radicans 
the pileus is bright yellowish-green; stem whitish below, 
yellow and strongly grooved above. 
B. parasiticus (from its parasitic habit). Plate XI. 5. 
P. 2-2J in., dry silky, yellowish tan. F. reddish. T. 
yellow, then reddish-orange, openings minute. S. \-2 in., 
incurved, hollow; colour of the pileus, flesh yellow. Para¬ 
sitic on the earth-balls (Scleroderma vulgare and verrucosum). 
At once known by the peculiar habitat. Said to be un¬ 
common, but is probably often overlooked, the colour of the 
pileus exactly resembling that of the peridium of its host. 
Autumnal. 
B. badius (badius, bay-brown). Plate XXXIV. 6. 
P. 3-5 in., rather viscid in wet, soon becoming dry and 
shining, bay-brown. F. thick (1-2 in.), white, slightly 
tinged blue near the tubes, and faintly red above when cut. 
T. about | in. long, depressed around the stem, yellow, 
becoming green when bruised ; openings yellowish, at once 
becoming deep bluish-green when bruised. S. 2-3 in., 
mottled and streaked with brown, never reticulated. In 
woods, chiefly pine, in ant. Common.
