ORDER IV. THELEPHOREI. 



Hymenium inferior or amphigenous, coriaceous or waxy, even, 

 rarely ribbed or papillose. Sporophores 4-spored. The begin- 

 ning of a new series with the hymenium not figurate. 



The hymenium is commonly said to be papillose, but these 

 (so-called) papillae are for the most part spurious or accidental, 

 generally arising from incrusted Sphcerice, and disappearing when 

 the fungus grows on an even surface. Thus also the occasional 

 papillae in Stereum rubiginosum, hirsutum, &c., arise from the 

 rough surface on which they grow. In a few species papilla 

 are present when they are in full vigour, but these collapse when 

 the plant dries. Fr. Hym. Eur. p. 629. 



GENUS XLIII. Craterellus (crater, a bowl). 

 Fr. Gen. Hymen. 



Hymenium waxy-membranaceous, distinct, but adnate to the 

 hymenophore, definitely inferior, continuous, smooth, even or 

 rugose. Spores white. Growing on 

 the ground, fleshy or membranaceous, 

 furnished with an entire pileus, stipi- 

 tate, autumnal, allied to Cantliarelli. 

 Fr. Hym. Eur. p. 630. 



* Tubfsfortn, pervious to the base of the 

 stem. 



** Infundibuliform, stem stuffed. 

 *** irregularly shaped, pileus and stem 

 fleshy. 



* Tub&form, pervious to the base 



of the stem. 



1. C. lutescens Fr. Pileus 2.5-10 

 cent. (1-4 in.) broad, fuscous, some- 

 what membranaceous, tubaeform, 

 soon pervious, undulated, flocculose. 

 Stem about 5 cent. (2 in.) long, hol- 

 low, smooth, yellow. Hymenium yellow, c., remotely ribbed, 

 even then rugose with interwoven veins. 



Craterellus. 



LXXXIII. Craterellus lutescens. 

 One-half natural size.
