ORDER IV— THELEPHOREI. 



Hymenium inferior or amphigenous, coriaceous or waxy, eve?i, 

 rarely ribbed or papillose. Sporophores 4-spored. The begi?i- 

 ni)ig of a new series with the hymenium not Jigurate. 



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 Sph&rice, and disappearing when 

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

 papillae in Stereum rubzginosum, hirsuttnn, &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). Craterellus. 



Fr. Gen. Hymen. 



Hymenium waxy-membranaceous, distinct, but adnate to the 

 hymenophore, definitely inferior, continuous, smooth, even or 

 rugose. Spores white. Growing on 

 the growid, fleshy or membranaceous, 

 furnished with an e?itire pileus, stipi- 

 tate, autumnal, allied to Cantharelli. 

 Fr. Hym. Eur. p. 630. 



* Tubceform, pervious to the base of the 

 stem. 



** Infundibuliform, stem stuffed. 

 *** irregularly shaped, pileus and stem 

 fleshy. 



* Tubaform, 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. 



LXXXIII. Craterellus lutescens. 

 One-half natural size.
