ON THE CLASSIFICATION OF FUNGI. 39 



I. CRATEEELLUS. Terrestrial. Fleshy, becoming putrescent. 

 Hymenium distinct, skin-like, smooth, even, or rugose. Pileus 

 and Stem continuous. 



II. THELEPHORA. Terrestrial and parasitic. Pileus fibrous, 

 destitute of cuticle, tough. Hymenium tough and fleshy, striate 

 or papillate, becoming rigid, at last flocculent. 



III. STEREUM. Parasitic. Pileus with cuticle. Hymenium 

 tough, thick, concrete with Pileus, naked, not beset with bristles. 



IV. HYMENOCILffiTE. Parasitic. Dry and leathery plants. 

 Hymenium even, and beset with short, stiff bristles. 



y. AURICULARIA. Parasitic. Hymenium spread upon 

 distant, reticulate folds, and becoming gelatinous in wet. 



VI. CORTICIUM. Parasitic. Hymenium fleshy, even, swollen 

 in wet, collapsed in dry weather. Surface often rimose. 



VII. CYPHELLA. Parasitic. Minute. Cup-shaped. Sub- 

 membranaceous. Hymenium inferior. 



VIII. SOLENIA. Parasitic. Minute, Tubular cups, with 

 narrowed mouth. 



IX. KNEIFFIA. Parasitic. Soft and fleshy, collapsing and 

 flocculent when dry. Hymenium rough with little bunches of 

 stiff bristles. 



THE GENERA OF CLAV ARIEL 



To this Order belong five Genera, distinguished as below. (PI. 

 XL) 



I. SPARASSIS. Terrestrial. Fleshy, frondose, laciniate. 

 Rather large. 



II. CLAVARIA. Terrestrial. Simple or frondose. Stem in- 

 distinct. Fleshy. Hymenium dry. 



III. CALOCERA. Parasitic. Small. Cartilaginous when moist. 

 Horny when dry. Hymenium viscid. 



IV. TYPHULA. Parasitic. Minute. Filiform. Stem and 

 club distinct. Hymenium waxy. 



V. PISTILLARIA. Parasitic. Minute. Stem and Club 

 distinct. Waxy, then homy. Cellular or fibrous. 



THE GENERA OF TREMELLINI. 



This Order contains eight Genera, particularized as follows. 

 Like some of the preceding Genera, however, which have been 

 described as minute, there are several of the Tremellini that 

 can scarcely be designated Mushrooms, but should belong to the 

 microscopic list. (PI. XII.)
