Spores whif». in the mass. 
*Flesh not changing colour, gills narrow, dec-urrent. 
227. Russula delica Fr. (L., delious, weaned). — Pileus 2 to 3in. (5 to 7.5 cm.), 
usually irregular, more or less convex, with the centre depressed, surface dull, 
milk white with rusty stains appearing or diffusely blotched with Sayal Brown

tralia — Mount Lofty (sometimes under trees), Second Valley Forest Reserve, 
Fncounter Bay, Kalangadoo (S.E.). March to July. 
The species may be recognised by the dull milk-white pileus which does not 
become dark in colour on drying but often shows rusty stains.

This species may perhaps belong to section II. 
228. Russula Flocktonae CM. et Cheel. (After -Miss -Margaret L. Flockton,

1 aste mild, occasionally slightly peppery. Spores elliptical, occasionally more 
spherical, warty, S.a to 10.8 x 7 to 8.5 n- New South Wales. April to June. 
(Plate V. Bottom figure.) 
Specimens, apparently of this species, have been collected at Mount Lofty in 
Apiil. The pileus was near Cinnamon Buff (xxix.), sometimes Auburn (n.) in 
the centre, the stem becoming brownish below or Light' Pinkish Cinnamon (xxix.), 
microscopically with fine hairs on the pileus, spores warty, 7.5 to 9 fi. The 
species seems to belong to this section. 
**Flesh becoming black. 
229. Russula adusta Fr. (L., adust us, scorched). — Pileus up to- 3in. (7.5 cm.),
