134 REVISION OF THE Хоктн AMERICAN HYDNACEAE 
the dried plant when mounted in water appear shriveled and may 
be thought to be curved and with peculiar dark bands. This ap- 
pearance may be of some value in separating species, but it entirely 
disappears if the spores are mounted in weak potassic hydrate and 
they appear then distinctly ovoid and highly transparent.

Plant stipitate, pileate, about 5 cm. long; pileus apparently 
flabelliform, branched ; branches flattened vertically and broaden- 
ing outwardly, о.5-3 cm. long, 1-20 mm. wide, in color white or 
pale alutaceous to reddish, subzonate, darker toward the margin 
and underneath; surface smooth, to subrugose, margin thin, 
deeply laciniate, apparently sterile ; stem, 1.3 cm. long by 1.5 mm. 
; substance membranaceous, subtranslucent, showing zona- 
tions distinctly by transmitted light, fibrous, thin, less than 0.5 mm. 
thick ; teeth minute, irregularly distributed, occasionally on both 
sides of pileus, blunt, conical, or flattened, often united at the base 
into longitudinal ridges, from which the tips of the teeth project 
like crests, the ridges sometimes appearing to anastomose forming 
pores and giving rise to the feature described by Berkeley as а 
porous hymenium ; teeth similar in substance to the pileus, 0.2- 
0.8 mm. long, 0.07—0.09 by 0.09-0.27 mm. beg Page hyaline, 
smooth, зоре озове; ovoid, guttulate, 3.6 x зим

Berkeley’s original description is unsatisfactorily brief and the 
above description drawn up from dried material may perhaps be 
supplemental. The species, however, should be easily recognized 
as it is wholly unlike anything else in the Hydnaceae. Its deeply 
laciniate, palmately branched pileus and membranaceous substance 
clearly distinguish it from all other pileate species. Its minute 
teeth, however, may cause it to be overlooked as a member of this 
family.
