Stem necked with smoke-grey (pi. 313, Ton 4). Gills very

 interdum gibbosus, deinde planus aut depressus, glaber, 

 margine striata, fumoso-cinereus. Lamellae subdis- 

 junctae, confertae, cinereo-albidae, marginibus percinereo- 

 albidis et subserratis. Stipes 10 ad 13 cm. altus, crassus, 

 sursum subattenuatus, substriatus, deorsum cavus, 

 fumoso-cinereus et punctatus. Volva vaginata, ampla, 

 fumoso-cinerea. Sporae sphericae, 10"4-18 li. 



This species is clearly closely related to, but quite dis- 

 tinct from, A. vaginata, Roze, which we have also collected. 

 We have come upon our species on several occasions, and it 

 has always presented the same characters. The colour of 

 the gills, punctate grey stem, and size and shape of the spores 

 are distinctive features. We have designated it "punctata" 

 from the appearance of the stem. (PI. xxviii.)

In May, 1917, an interesting form was found at Mosman, 

 Sydney, growing in a dense caespitose mass at the base of a 

 stump. The cap was almost black with dense short fibres. 

 There were definite remains of a pale-brownish ring | inch 

 below the cap, whilst just below the cap itself was a flimsy 

 veil rupturing to form a very definite second ring. 



93. Armillaria mxcida, Schrad., var. exanmilata, var. 

 nov. — Cap up to 4 inches in diameter, slightly convex, then 

 plane, glutinous, edge a little striate, whitish to pale stone- 

 brown, cuticle peels. Gills very slightly sinuate, slightly 

 ventricose, moderately distant to distant, white. Stem 

 3J inches high, slender to quite stout, bulbous below, attenu- 

 ated upwards, slightly fibrously streaked, fibrous, tough, 

 white to whitish, solid. Spores spherical, granular, thick- 

 walled with a "nucleus," white, 15*5 to 24 /x, basidia and 

 hyphae large in proportion. On rotting fallen trunk, Mum- 

 mulgum Brush, near Casino, December, 1916. 



Even in young specimens we can find no sign of a ring. 

 The plants are obviously like a large ringless Armillaria
