incurved on drying, irregular, undulate to lobed ; context soft- 
fleshy, rosy-gray, about 5 mm. thick; tubes slightly decurrent, 1-2 
mm. long, whitish-stuffed when young, white to pale-umbrinous 
within, mouths subangular, unequal, 2-4 to a mm., edges thin, 
entire to fimbriate, lacerate with age, white when young, becom- 
ing gray or umbrinous; spores subglobose, hyaline, echinulate, 
5-6 X 4-5~5 i *- ; stipe central, thick, short, bulbous at the base, with 
surface and substance resembling that of the pileus, but darker 
in color, 4-5 cm. long, 1-1.5 cm. thick. 
Found sparingly on the ground in open woods in New York, 
New Jersey, and Alabama. The specimens here figured were 
collected by Dr. F. M. Bauer near Amityville, Long Island, in 
September, 1911. The genus Scutiger approaches very near the 
Boletaceae, but the species are somewhat tougher and dry more 
easily. Of the dozen or more members of the genus in this 
country, all except two are very rare and local.

Plate 106. Upper Figure 
Pileus imbricate-multiplex, 15-40 cm. in diameter; pileoli very 
numerous, branching from a common trunk, imbricate or con- 
fluent, variable in size and shape, dimidiate to flabelliform, 1.5-6 
cm. broad ; surface smoky-gray, fibrillose, radiate-striate ; margin 
thin, undulate or lobed, strongly indexed when dry ; context white, 
very thin, tough, fragile, having the odor of mice; tubes white, 
2-3 mm. long, mouths circular and regular when young, 3 to a 
mm., often large and angular with age, edges white, thin, entire 
to lacerate ; spores subglobose to ellipsoid, smooth, hyaline ; stipe 
tubercular, white, connate-rimose. 
This large, branched species grows commonly in Europe and 
North America at the base of oak trees or arises from their 
roots, on which it feeds. It also attacks the roots of chestnut 
trees, and in the Italian chestnut orchards it is often allowed to 
destroy its host because it is much esteemed in that region for 
food. It must be eaten when young or it will become too tough.
