Poria sp. 
On dead Vernonia arborea, altitude 4500 ft., West Java, C. 
Hartley (in Mo. Bot. Gard. Herb., 59506). 
The fructification is resupinate on a rotten limb, and covering 
an area 10 cm. long, 2-314 cm. broad, between warm buff and 
antimony yellow of Ridgway in dry condition; pores with mouths 
angular, about 4 to а mm. The hymenium is deteriorated and 
shows neither basidia nor spores.

HYDNACEAE 
Hydnum obrutans Burt, n. sp. Plate 2, fig. 2. 
Type: in Mo. Bot. Gard. Herb. 
Fructification resupinate, long and widely effused, not separable, 
white, becoming up to 214 em. thick by the older teeth becoming 
buried and grown together under those of more recent formation, 
soft and easily sectioned when moistened; teeth white, cylindric, 
subulate, oblique, nearly parallel with the substratum, free 
portion 1-2 mm. long, about 3-4 to a mm.; no setae, cystidia, 
nor gloeocystidia; basidia simple; spores hyaline, even, globose, 
4% y in diameter, copious. 
Fructifications large; fragments fractured on all sides, up to 
10 em. long, 216 cm. wide, 5 mm.-214 cm. thick; teeth about 
200-250 y in diameter. 
Causing heart rot of living trunks of Quercus sp., 4500 ft. 
altitude, West Java, C. Hartley, type (in Mo. Bot. Gard. Herb., 
59520). 
This species is noteworthy by its parasitic nature, great thick- 
ness attained through consolidation together of the buried teeth 
comparable with that of the tubes of a Fomes, white color, and 
fracturing into chalk-like masses when dry but soft and not truly 
fleshy nor caleareous when moistened.
