40 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Pileus coriaceous, rigid, thin, broadly wedge-shaped to dimidi- 
ate, sessile, tapering to a point of attachment, the upper surface 
tawny olive of Ridgway, somewhat radiately rugose, short tomen- 
tose, with the tomentum disappearing more or less near the margin 
in narrow zones and there showing the pallid quaker drab surface 
of the bared areas, the margin more or less lobed; in structure 
800 u thick, with the intermediate layer composed of densely 
and longitudinally arranged, slightly eolored hyphae, and bordered 
on the upper side by а broad dark zone which bears the tomentum 
of the covering; hymenium glabrous, pallid quaker drab, blacken- 
ing when sections are treated with dilute potassic hydrate; no 
setae, cystidia, nor gloeocystidia; no spores found. 
Pilei 4-5 cm. long, 5-6 cm. broad. 
On dead wood, Tjibodas, West Java, Е. D. Rands, comm. 
by C. Hartley, type (in Mo. Bot. Gard. Herb., 59518). 
The two pilei received have had the marginal portions broken 
away near the point of attachment but lead me to believe that 
they were not connected with a reflexed portion nor umbonate- 
sessile. The hymenium, margin, and some zones of the upper 
surface of the pileus are tinged with pallid quaker gray of Ridg- 
way, i. e., livid like the hydrogen arsenide flame. In lactic acid 
mount the sections show their hyphae to be somewhat rough- 
walled, as though resinous incrusted—especially so the tomentum 
on surface of pileus, the dark zone bearing the tomentum, and 
the hymenium; dilute potassic hydrate blackens all the incrusting - 
matter and also the contents of many hyphae. I have observed 
similar inerusting matter and color changes in no species studied 
by me heretofore.
