237. Russula viridis del. (L., viridis, green), — Pileus up t'o 2 to 2Jin. (5 to 
6.2 cm.), convex, slightly depressed in the centre, surface dull, edge not striate, 
margin nearly straight, pellicle separable, probably slightly sticky when moist, 
tints of Grape Green in the centre becoming Lincoln Green (xll), at the 
periphery passing into pallid greyish-green and nearly white or near Yetiver 
Green (xlvu.) and paler or darker in places. Gills equal, fading off somewhat 
as the swollen apex of the stem is reached, moderately close, Harrow, sometimes 
forked near the stem, creamy white. Stem 14 to IJin. (3.7 to 4.4 cm.), Jin. 
(16 mm.) thick, slightly rugose, swollen below and attenuated upwards or equal, 
solid, white. Flesh fragile, white. Taste mild. No smell. Spores spherical 
pear-shaped, finely warty, nearly pure white but slightly tinted cream, 7.5 to 
9 x 5.5 to 6.5 /x. Apparently no cystidia on the pileus. On the ground. South 
Australia — Mount Lofty. March, June. 
Russula Marine Peck, in its Australian form, perhaps belongs more properly to 
this section.
