Pileus coriaceous, cup-shaped, flabelliform or orbicular, drying 
tawny olive, spongy tomentose but with the tomentum thinning 
out towards the margin and the surface there zonate, short- 
stipitate or sessile, the margin thin, entire; hymenium wood-brown, 
paler towards the margin, densely, minutely warted, with very 
numerous, short, radially elongated ridges not continuous in а 
branched system; pileus in structure consisting of an intermediate 
layer, about 800 д broad, composed of interwoven, longitudinally 
arranged, hyaline hyphae 214-414 y in diameter, of a broad 
layer of the tomentum of the upper surface of the pileus, and of 
а hymenial layer containing numerous flexuous gloeocystidia up 
to 60 X 416-6 u; spores hyaline, even, 3 x 2 u; hymenial warts 
up to 80 u high, 100-200 џ in diameter at the base, composed of 
a mass of erect, granule-incrusted hyphae; no cystidia found. 
Pileus up to 5 em. in diameter. 
On frondose wood. Florida. 
The hymenial warts are conspicuous in sections, even though 
not appreciably elevated above the hymenial surface, by contents 
of localized masses of granule-incrusted hyphae. This incrusting 
matter is of different nature from that usually present in the 
walls of hyphae, because it dissolves completely when the sections 
are treated with dilute potassium hydrate solution; lactic acid 
does not destroy the incrusting matter.
