STROPHARIA. 407 



Agaricus (Stropharia) scobinaceus, Fries, Epicr., p. 217; 

 Cke., Hdbk., p. 201. 



On ash trunks. Subcaespitose ; moist and fragile. 



Caespitose. Allied to S. caput-Medusae, but not so showy, 

 moist, and more fragile. Stem hollow, attenuated from the 

 thickened (solid ?) base, fibrillose, white, apex mealy ; ring 

 superior, fugacious, white. Pileus thin, hemispherical then 

 expanded, gibbous, slightly sulcate, covered at first with 

 crowded, adpressed, blackish, evanescent scales, at first 

 brown, from the centre towards the margin livid then 

 yellowish, margin greyish -violet. Gills adnate, crowded, 

 crenulate, whitish flesh-colour then purplish. (Fries.) 



The type of this species is nearly of the same stature as 

 H. caput-Medusae, but the whole plant is thinner, more 

 fragile, and less handsome. There are various intermediate 

 forms which seem to connect the true combining features of 

 both. I have found several well-marked stages between 

 them. Spores ellipsoid-elongate, 7-8 x 3 /x. (Plow.) 



Stropharia Jerdoni. B. and Br. 



Pileus 2 in. across, campanulate, obtuse, with a broad 

 fleshy umbo, ochraceous, dry, adorned with snow-white 

 superficial, evanescent scales, cuticle not peeling off; gills 

 adnate, sending a line down the stem, but not truly decur- 

 rent, pallid then brown, transversely striate ; stem 3 in. 

 high, 2-3 lines thick, cylindrical, snow-white and pulveru- 

 lent above, brownish, with silky transverse scales below, 

 hollow, ring superior, deflexed ; spores purple-brown.

 n. 913, pi. xiv., f. 2 ; Cke., Illustr., 541 ; Cke., Hdbk., p. 201. 



On fir-stumps. Berkeley in his diagnosis says the pileus 

 is brown when dry, but in the type it is ochraceous, having 

 probably changed with age. 



Stropharia spintriger. Fr. 



Pileus 2-4 in. broad, rather fleshy, ovate then expanded, 

 obtuse, even, glabrous, pale brown pinkish-tan then whitish ; 

 gills adnate, crowded, 12 lines broad, brownish ; stem 2-3 

 in. long, 3 lines thick, equal, white, floccosely-fibrillose, apex 

 naked, hollow ; ring distant, thin, fugacious.
