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; hjTnenium wood-brown, 

 paler towards the margin, densely, minutely warted, with very 

 numerous, short, radially elongated ridges not continuous in a 

 branched sj-^stem; pileus in structure consisting of an intermediate 

 layer, about 800 [i broad, composed of interwoven, longitudinally 

 arranged, hyaline h>^hae 2Y2-^]A ^ in diameter, of a broad 

 layer of the tomentum of the upper surface of the pileus, and of 

 a hj-menial layer containing numerous flexuous gloeocj^stidia up 

 to 60 X 43/^-6 [x; spores hyahne, even, 3 X 2 [ji; hjTnenial warts 

 up to 80 [X high, 100-200 ^ in diameter at the base, composed of 

 a mass of erect, granule-in crusted hyphae; no cystidia found. 



Pileus up to 5 cm. in diameter. 



On frondose wood. Florida. 



The h^menial w^arts are conspicuous in sections, even though 

 not appreciably elevated above the hymenial surface, by contents 

 of locahzed masses of granule-incrusted hjTphae. 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 w^ith dilute potassium hydrate solution; lactic acid 

 does not destroy the incrusting matter.
