19. Cantharellus, Adans. 

 Pileus often fleshy but thin in small species, often lobed or 

 irregular ; gills more or less decurrent, narrow, edge thick, 

 entire ; stem central, excentric, or absent ; spores white, 

 smooth. 



Cantharellus, Adanson, Fung. Ord., v. 



Distinguished among white-spored genera with decurrent 

 gills by the narrow entire gills having the edge blunt or 

 thickened. Growing on the ground. 



55. Cantharellus umbricejjs, Cke., Grev., vol. viii., p. 54, 



pi. 132, figs. 1, 2 ; Sacc, Syll. v., no. 1902. 



Pileus fleshy, soft, subglobose, then expanding, then de- 

 pressed, margin incurved, glabrous, umber, about 3 cm. 

 diameter ; gills very narrow, thick, forked, not crowded, 

 dingy-orange; stem about 4 cm. long and 1cm. thick at the 

 slightly swollen base, solid, white with a tinge of yellow; 

 spores globose, 4 fx diameter. 



On the ground. Maungaroa, New Zealand. 



As the species was founded upon the examination of a 

 single specimen, accompanied by a coloured drawing, it is 

 probable that the size and some minor details given above 

 may require modification. 



20. Omphalia, Fries. 

 Pileus symmetrical, usually very thin, depressed or infundi- 

 fuliform; gills truly decurrent, edge thin, entire; stem 

 distinctly cartilaginous externally, tubular, but the cavity 

 is frequently stuffed, especially when young, usually widen- 

 ing upwards into the pileus ; spores hyaline. 



Omyhalia, Fries, Syst. Myc, i., p. 162 (as a subgenus of 

 Agaricus). 



Agreeing with Clitocyhe in the decurrent gills, but readily 

 known by the_ externally poHshed, cartilaginous stem. The 

 species are with few exceptions small, and many grow on 

 wood, twigs, &c. Smell obsolete, or nearly so, in all the 

 species. 



* Pileus even. 



56. Omphalia anthiceps, Berk, and Curt., Journ. Linn. Soc. 



(Bot.), vol. X., p. 286 ; Sacc, Syh. v., no. 1222. 



Densely tufted ; pileus deeply umbilicate, often somewhat 

 umbonate but the umbo sunk in the central depression, thin, 

 even, glabrous, white, disc tinged brown, 1-1-5 cm. broad; 

 gills adnato-decurrent, distant, rather broad, white ; spores 

 subglobose, 4-5 /x. diameter; stem 1-1-5 cm. long, slender, 

 glabrous, white, hollow. 



Densely caespitose, on decaying logs. New Zealand. Cuba.
