OF SOUTH AUSTRALIA. 
151 
There are several European and American species 'which resemble eaeli other 
in becoming dark when drying. In 11. nigricans Fr, the gills are distant to 
subdistunt and the white flesh turns reddish when bruised and then blackish. 
In It. densifolui Seer., the gills are actuate to subdecurrent and close and the 
greyish-white flesh as well as the whitish stem become reddish when bruised and 
then blackish, h. sordida Peck has whitish flesh which becomes blackish without 
a reddish stage, a whitish stem becoming black when handled, and close adnate 
to subdeeurrent gills, li. adusta Fr. has flesh which does not change on bruising, 
close adnate to subdecurrent gills and a white stem becoming sooty-grey. The 
Australian plant seems best referred to the latter. 
11. Pellicle of the pileus dry, adnate, rarely possessing eystidia, usually 
breaking up into flocc-i, granules or areolae. Margin rounded, rarely 
striate, not involute. Uill.s with a very broad, rounded apex. Spores 
whitish creamt- colour in mass. 
Xo South Australian species recorded. 
III. I elliele of tin 1 pileus viscid, separable at the margin and possessing 
eystidia. Margin subacute, rarely striate in old age. Flesh firm. 
Taste mild. Gills attenuated in front, often forked and unequal. 
Spores verrueose, small, white in the mass. 
-30. Russula, cy.anozantha (Schaeff.) Fr.? (Gr„ hyams, blue; mnthos. yellow). 
— Pileus 2 Jin. (5.6 cm.), upturned, pallid brownish- white with dull greyish -green 
blotches. Gills adnate, moderately close, cream. Stem 1 in. (2.5 eni.), stout, 
attenuated downwards, slightly rough, white. Taste mild. Spores subspliericah 
slightly warty, 6 to 7 g. On the ground. South Australia — Mount Lofty. April.' 
There is doubt as to whether this Australian plant is rightly referred to 
this species. 
2.11. Russula Cheelii Clel. (After Edwin Cheel, Curator of the Herbarium 
Botanic Gardens, Sydney) .—Pileus 3in. (7.5 cm.), convex with a central depres- 
sion, then upturned, viscid when moist, edge slightly rugose. Warm Buff (xv. ). 
Gills adnate, close, often forked near the stem, with occasional short ones at' the 
pel iphery, narrow, attenuated both ways, cream-coloured becoming a little spotted. 
Stem 24m. (6.2 cm,.), tin. (2.1 cm.) thick above, nearly equal or slightly 
attenuated downwards, surface matt, slightly striate, stuffed, white. Taste mild 
Spores pear-shaped, warty, 8.5 x 6.5 g. South Australia— Kuitpo. May. 
This species probably belongs to this section though eystidia have not been 
recorded on the pileus.

\ ell o wish, oeliraceous or brownish, sometimes olivaceous brown, never 
red or violet. Margin straight, more or less striate, subacute. Taste 
acrid. Spores pure white or cream. 
232._ Russula pectinatoides Peck (!>., pecten, a comb; Gr., eidos, like). — Pileus
