1 8 GUIDE TO THE MODELS OF FUNGI. 



than 2| in. in diameter ; gills adnato-sinuate, broad, thick, distant, 

 shining white; the stalk is six inches or more long, pale brown, 

 straight, rigid, generally twisted and attenuated upwards, the base 

 continued as a tail-like root, sometimes six inches long and tapering 

 to a point, the whole of this root being buried in the ground or in 

 rotten wood. Odourless. 



A. radicatus is extremely common, and generally grows in a 

 solitary manner among grass on and near decaying stumps, in 

 woods and by hedgesides. There is a wholly shining-white form, 

 and a common small form with a pileus one inch or less across. 



In the Botanical Department there is a drawing of a specimen 

 of this species with a pileus 84 in. in diameter and a stem (including 

 the rooting base) 22 in. long. 



The pileus is dry in its young state, glutinous (at the disc only) 

 at maturity, and becomes dry again with age. 



28. Agaricus fusipes Bull. — Pileus fleshy, rufescent-brown, 

 smooth, dry, umbonate, often cracked ; gills adnexed, broad, distant, 

 firm, white, then pale brown, often spotted with foxy-brown stains ; 

 stalk rufous-brown, long, stuffed, cartilaginous externally, swollen 

 in the middle, twisted, cracked, longitudinally striate and attenuated 

 to a point at the rooting base. 



This species is common on old stumps, where it usually grows 

 in a densely caespitose manner ; it is very variable in size. It is 

 generally considered esculent ; the taste is not unpleasant, but the 

 flesh is tough. Dr. Badham, in his Esculent Funguses of Britain, 

 recommends this fungus for pickling. 



29 Agaricus maculatus A. & S. — Pileus fleshy, compact, con- 

 vexo-plane, even, smooth, margin thin, at first involute; gills sinuate, 

 almost free, very crowded, linear ; stalk hard, externally cartilaginous, 

 somewhat ventricose, striate, base attenuated, rooted. Taste acid. 



It is a typical example of a large Collybia, inhabiting woods, 

 usually under beeches and firs ; it may be at once known by its 

 large size, and its creamy or pale buff" colour, spotted and stained 

 foxy-red ; it sometimes becomes almost wholly ruiescent. 



30. Agaricus velutipes Curt. — Pileus tawny-yellow, convex, 

 then plane, moderately fleshy, smooth, viscous ; flesh yellowish, 

 watery, and soft; gills slightly adnexed, almost free, somewhat 

 distant, pallid yellow; stalk ^ough, externally cartilaginous, covered 

 with dense brown — sometimes almost black — velvety down. 



It sometimes springs from a luxuriant golden byssoid mycelium 

 formerly called Ozoncutn aurcum and Byssus barbaia. The stem and 

 mycelium are frequently luminous. 



A. 7.<clutipcs is a very common late-growing species ; it may be 

 found through the entire winter in crowded clusters on trunks and 

 stumps of all kinds in the parks and gardens both in town and 

 country ; the stem is 'seldom so attenuated as shown in the model,
