PSILOCTBE. 373 



Psilocybe semilanceata. Fr. 



Pileus ^— J in. across, suTDmembranaceous, acutely conical, 

 sometimes almost cuspidate, margin more or less persistently 

 incurved, slightly viscid and striatulate -when moist, when 

 dry very pale yellow or pallid with tinges of yellow, or blue- 

 green, shining ; gills subdistant, broadly adnate, brown 

 then blackish with purple tinge, margin pale ; stem 2—3 in. 

 long, 1^ line thick, equal, tough, wavy, silky-fibrous and 

 shining, pallid, with minute, evanescent fibrils at the apex, 

 stuffed with silky fibres ; spores brown, 10-12 X 6 /x. 



Agaricus (Psilocyhe) semilaneeatus, Fr., Obs., ii. p. 178 ; 

 Cke., must., t. 572; Cke., Hdbk., p. 211. 



Amongst grass in pastures, &c. Gregarious, pileus som.e- 

 times quite obtuse, from which condition every transition 

 exists to cuspidate. 



Fries says that he has observed the presence of a sub- 

 annulate ring in the young stage of the present species and 

 conseq:uently it might with equal propriety be placed in the 

 genus Stropharia, after S. semiglobata. 



Var. caeruleseens. Cooke. 



Pileus rather obtuse, bare of stem, more or less distinctly 

 tinged with blue ; spores, 10-12 x 6 /t. 



Cke., niustr., t. 573. 



Amongst grass in pastures. 



It is doubtful as to the propriety of considering the above 

 a true variety ; I do not consider it as even a permanent 

 form ; in the type the relative prominence of the umbo is 

 very variable, and there is frequently a tinge of blue at the 

 base of the stem, and Cooke's variety, if retained, rests 

 entirely on the distinct blue tinge at the base of the stem. 



II. EIGIDI. Veil absent. Pileus scarcely pelliculose, flesh 

 frequently splitting, Tiygrophanous. Gills adnexed, rarely 

 adnate. Stem rigid. 



Psilocybe canobrunnea. Fr. 

 Pileus 2-3 in. broad, fleshy, convex then plane, obtuse, 

 hygrophanous, rather viscid when moist, fleshy-brown, pale 

 when dry; stem about 2 in. long, \ in. or more thick, 

 whitish, squamulose, rooting, hoUow ; gills almost free, 

 crowded, broad, ventricose, pallid then brownish-purple.
