57b. Psalliota arvensis, var. fragrans, var. nov. (pi. xii., 

 figs. 3 and 4). — We have met with, this distinct variety on a 

 number of occasions. It may be readily distinguished from 

 the common field mushroom by slight yellowish stains on the 

 cap, by the pallid colour of the gills when young, and by 

 the definite though slight fragrant smell. Pileus up to 

 3tf inches in diameter, usually much less, at first hemi- 

 spherical, then convex, sometimes conical with a depressed 

 centre, sometimes gibbous, smooth, shining, pure white, later 

 with faint rusty or yellowish stains, when bruised turning 

 yellowish. Gills close, free or just reaching the stem, whitish 

 for long, then pallid greyish or pale creamy-pink, finally 

 purplish -brown. Stem 3| inches high or less, sometimes up 

 to ij inch thick, slender or stout, slightly hollow or solid, 

 with a pointed root, white, sometimes later with a reddish 

 tint. Texture sometimes tougher than that of P. campestris. 

 Slight but definite fragrant smell. Spores sometimes 7 to 

 8'5 x 4'2 to 5'2 /x, sometimes 5*2 x 3'4 y,; of 11 collections 

 in which the spores were measured, 5 gave the larger size 

 and 5 the smaller, whilst one varied from the higher to the 

 lower : there seem to be no other essential differences 

 between the two.
