79. Panaeolus semilanceatus, Peck: N. York State Mus., 

 Mus. Bull. 131, p. 37. — Peck's description of this species is 

 as follows: — "Pileus thin, conic-ovate, umbonate, greyish- 

 brown ; lamellae ascending, black "when mature; stem slender > 

 glabrous, hollow, brown : spores ellipsoid, compressed variable 

 in size, black, 12 to 18 x 8 to 12 ji. Similar to Psilocybe 

 semilanceata , Fr. , in size and shape, but differing in colour 

 and spore character." We have a common species, growing; 

 amongst grass in the Sydne}^ district, that resembles closely 

 dried specimens of Psilocybe. semilanceatus, kindly sent to 

 us by Miss E. M. Wakefield from England, but differing in 

 the spores being black. It appears to be Peck's species. 

 We describe specimens (pi. xi., fig. 6) as follows: — Pilsus 

 about | inch high and \ inch wide or larger, conico-ovate, 

 somewhat acuminate, constricted below and inturned so as 

 sometimes to almost completely hide the gills, always showing 

 some degree of inturning, occasionally slightly sticky, edge 

 slightly striate, pallid greyish-straw, somewhat browner on 

 top, pallid silky when dry, sometimes, according to moisture,, 

 showing a greyish band near the edge. Flesh whitish, thick 

 in the centre. Gills ascending, adnate, about J inch deep, 

 greyish-black, edge white and very finely toothed. Stem up 

 to 25 inches high, silkv shining- hollow, twisting on section, 

 somewhat cartilaginous and stringy, slightly attenuated 

 downwards, pale brown. Spores dark brown to black, oval, 

 ends pointed, 12 to occasionally 13"8 or 15'5 x 7 to 8'5 jm.
