smooth, continuous, elliptical, ends obtuse, 18-22 x 11-12 p.; 

 paraphyses septate, clavate and brownish at the tips. 



Distinct, repanda, Sacc., Syll., viii. n. 373. 



Specimens communicated by Greville to Berkeley accepted 

 as typical. These specimens are part of the gathering 

 collected by Wauch and Greville under beech-trees at 

 Foxhall, and figured in Scot. Crypt. Flor., pi. 59. 



On the ground, often in beech- woods ; also on decayed 

 trunks. 



Solitary, or several growing close together in a tufted 

 manner, sessile, large, 14 inches broad, carnose, brittle, very 

 concave while young, but gradually expanding until it 

 becomes quite plane, sometimes splitting at the edge, but 

 often entire, waved and somewhat lobed. Margin crenate 

 and somewhat reflexed. Colour of the hymeniuin dilute- 

 brown, of various shades ; outer surface whitish, pulverulent. 

 The base is often plicate and radicating. Pileus when 

 splitting never convolute. (Greville.)

Gregarious or caespitose and often distorted by mutual

 differs from both in colour, habit, and fruit. (Smith.) 



Unknown to me.
