59. Omphalia colensoi, Berk., Flora N.Z., ii., p. 173; Hdbk. 

 N.Z. Flora, p. 602 (as Agaricus (Omphalia) colensoi) ; 

 Sacc, Syll. v., no. 1264. 



Pileus thin, rather deeply umbilicate, sometimes almost 

 funnel-shaped, glabrous, entirely covered with very fine radial 

 wrinkles (when dry), margin incurved, 1-1-5 cm. across ; gills 

 pallid, rather narrow, slightly decurrent, thin and not distant ; 

 spores hyaline, subglobose, about 4 x 3 /x ; stem 1-1-5 cm. 

 long, slender, minutely scurfy, then becoming glabrous. 



On the ground, amongst sand and scraps of wood, wet 

 logs, &c. Ngaawapurua, Northern Island, New Zealand. 



The pileus appears to have been whitish when fresh, stem 

 darker. Distinguished from 07np]iaiia umhellifera by the thin, 

 rather close gills. Type specimens examined. 



60. Omphalia pyxidata, BuUiard, Champ. France, tab. 568, 

 fig. 2; Sacc, Syll. v., no. 1199. 



Pileus membranaceous, umbilicate, then infundibuliform, 

 almost glabrous ; radially striate and brick-red or rufescent 

 when moist, hygrophanous ; whitish and minutely silky 

 when dry; 1-5-2-5 cm. across; gills decurrent, rather distant, 

 narrow, flesh-colour, then yellowish ; spores 7-8 x 5-6 /a ; 

 stem 2-2-5 cm. long, 2 mm. thick, even, tough, pale-rufes- 

 cent, stufl'ed, then hollow. 



Among short grass, &c. Dannevirke, New Zealand. 

 Europe, Australia. 



Characterized by the dull-red tinge of the entire fungus 

 and the narrow gills. 



Specimens of this species have been found amongst the 

 New Zealand fungi sent to Kew by Colenso, hence its occur- 

 rence does not rest on the doubtful identification of the 

 specimens alluded to in the " Handbook of the New Zealand 

 Flora," p. 602. 



61. Omphalia umbellif era, Linn., Suec, no. 1192; Flora N.Z., 

 ii., p. 173; Hdbk. N.Z. Flora, p. 602; Austr. Fung., 

 p. 28; Sacc, Syll. v., no. 1241. 



Pileus convex, then almost plane and obconic, often more 

 or less wavy and upturned, radiately striate when moist, even 

 ^nd silky when dry, 1-5-2 cm. across ; gills decurrent, very 

 distant, broad behind, whitish or coloured hke the pileus ; 

 spores broadly elliptical, 7 x 4 ;u, ; stem about 1 cm. long and 

 2 mm. thick, coloured like the pileus, base downy, imper- 

 fectly hollow. 



On the ground. Northern Island, New Zealand. Austraha, 

 Tasmania, Ceylon, Europe, Greenland, United States. 



Very variable in colour ; most commonly whitish, becoming 

 shining white when dry, but also grey, yellow, brownish,
