purplish-brown scales or to become blotchy bluish-green and 

 brownish-yellow in the centre, when old pale brownish with 

 shades of dull bluish-green, cuticle separable. Gills adnate, 

 close, all equal, sometimes forked, sometimes slightly anas- 

 tomosing at the stem, diminishing towards the stem and 

 rounded externally, white or creamy. Stem up to If inch 

 high and up to § inch thick, slightly attenuated downwards, 

 mealy, very slightly striate, solid, white. Taste mild. Shed 

 spores white, spherical, warty, 7 to 8'5 /x. Neutral Bay, 

 Sydney, March and May, 1917; Narrabeen, March, 1916; 

 North Bridge, Sydney, July, 1916. (Miss Clarke, Water- 

 colour 147.) A similar plant obtained at Sydney in March, 

 1916, had a very slightly peppery taste. Probably the same 

 species, with the cap pallid brownish-white with dull greyish- 

 green blotches, was collected at Mount Lofty, S. Austr., in 

 April, 1917 (spores 6 to 7 ja). 



114. Russida granulosa, Cooke: Handb., p. 332; Cooke: 

 Illustrs., pi. 1038; Massee : Brit. Fung. Flora, iii., p. 69. — 

 The punctate brown spots on the stem, the cystidia, and the 

 acrid taste seem to indicate with reasonable certainty that 

 the following is this species: — Pileus when young somewhat 

 dome-shaped and irregular with the edge sharply turned in, 

 then irregularly convex, finally expanding up to 4 inches 

 in diameter, smooth but sometimes with a few wrinkles, or 

 slightly fibrously streaked, edge plicate, somewhat viscid when 

 moist, cuticle not separable, yellowish-brown. Flesh thick, 

 becoming attenuated towards the edge, white. Gills adnate 

 to adnexed, moderately close, edges darker and very slightly 

 serrate, creamy, when bruised becoming brownish. Stem. 

 1^ to 2\ inches high, attenuated downwards, mealy-white 

 with a tinge of ochre or with fine scattered punctate brown 

 spots. Taste intensely peppery and somewhat bitter. Spores 

 warty, 7 to 9 fx ; a few projecting acuminate cystidia, 

 42x12 /x. Narrabeen, March, 1916, and February, 1917; 

 Kew, January, 1917; Neutral Bay, Sydney, March, 1917.

115. Russida pectinatoides, Peck. — Peck's description (N. 

 York State Mus., Bull. 116, p. 90) of this species is as fol- 

 lows: — ' c Pileus thin, broadly convex, becoming nearly plane 

 or centrally depressed, viscid when moist, widely tuberculose 

 striate on the margin, dingy straw colour, brownish, yellowish- 

 brown or cinerous brown, sometimes darker in the centre,

 spongy within, white; spores whitish, subglobose ; '00025-'0003
