Type: in Lloyd Herb, and in Mo. Bot. Gard. Herb. 



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 a 

 branched system; pileus in structure consisting of an intermediate 

 layer, about 800 y. broad, composed of interwoven, longitudinally 

 arranged, hyaline hyphae 2^-4}^ ;x in diameter, of a broad 

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

 a hymenial layer containing numerous flexuous gloeocystidia up 

 to 60 X 43^-6 [l; spores hyaline, even, 3 X 2 p; hymenial warts 

 up to 80 {x high, 100-200 \l in diameter at the base, composed of 

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



Pileus up to 5 cm. 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.
