346 FUNGUS-FLORA. 



narrow, whitish, then grey, finally blackish ; stem 1-1^ in. 

 long, rather curved, mealy then smooth, fragile, hollow. 



Agaricus (Psaihyrella) disseminatus, Pers., Syn., p. 403 ; 

 Cke., Hdbk., p. 223 ; Cke., Illustr., pi. 657 B. 



About trunks of trees, and on the ground. Forming large, 

 dense tufts ; very slender and fragile, soon flaccid, but not 

 deliquescent. 



Crowded. Pileus ovate, conical, at length campanulate, 

 ^-^ in. from the base to the apex, striate and plicate, 

 membranaceous, pale buff or reddish- brown, at length grey, 

 becoming flaccid and dissolving. Lamellae distant, narrow, 

 pale brown. Stipes 13 inches long, slender, weak, brittle, 

 crooked, hollow, pale yellowish, whitish or greyish. Par- 

 ticularly partial to old willow-trees, and when growing on a 

 stump of a felled tree often covering nearly a square yard.

GOMPHIDIUS. Fries, (figs. 7-9, p. 303.) 



Stem central, expanding gradually and without differentia- 

 tion into the fleshy pileus ; gills decurrent, distant, soft, 

 rather mucilaginous, edge acute ; veil floccose, viscid, 

 forming an imperfect ring round the stem ; spores large, 

 elongato-fusiform, smoky-olive; cystidia large. 



Gomphidius, Fries, Epicr., p. 319 ; Fries, Hym. Eur., p. 399 ; 

 Cke., Hdbk., p. 284. 



A very distinct genus, characterised by the peculiar 

 tough, elastic substance of the entire fungus, pileus glutinous 

 when moist, as is also the floccose veil; gills decurrent, 

 generally more or less tinged with dingy olive at maturity, 

 soft and mucilaginous. Spores very large, elongated and 

 narrowly fusiform, dingy olive, in form resembling those 

 characteristic of the species of Boletus ; a genus without close 

 affinities, and might with equal reasons have been placed in 

 any other group with coloured spores. Fries says, from the 

 habit, its position is between Cortinarius and Hygrophorus. 



Gomphidius glutinosus. Schaeff. 



Pileus 2-5 in. across, obtuse, margin for a long time 

 incurved, glutinous, purplish-brown or fulvous, flesh thick 

 except at the incurved margin, white; veil viscid; gills
