Fructifications dark fuscous to fawn-color, coriaceous-soft, 

 cespitose, obconic, with a short stem-like base, or dimidiate and 

 sessile, or incrusting and effuso-reflexed ; pileoli more or less 

 imbricated, sometimes laterally confluent, fibrous-squamulose 

 and usually strigose, thin, margin fibrous-fimbriate and lacin- 

 iate ; hymenium inferior, papillose, fuscous to fawn-color ; spores 

 pale fuscous, irregular, angular, sometimes slightly tuberculate, 

 6-9 x Q/i. 



Clusters 5-8 cm. in diameter, with single pileolus about 3 cm. 

 long and broad; obconic pileus 2-3 cm. in diameter; dimidiate 

 pileolus 1^-2 cm. long, 2-3 cm. broad, about 1 mm. thick. 



On sandy ground in bare fields and at base of trunks and 

 from fallen twigs and leaves in pine woods. Canada to South 

 Carolina, and in Michigan, Jamaica, and Alaska. July to De- 

 cember. 



My observations of this species acquired from specimens 

 received and from seeing it growing abundantly near Middle 

 Grove, N. Y., seem to show that the medium from which this 

 fungus derives its food produces an interesting effect on the 

 fructification. Growing from bare, sandy ground the fructifica- 

 tions are dark fuscous in color, and may be flattened clusters of 

 imbricated pileoli, or of the obconic-pileus type composed of 

 ascending pileoli confluent laterally, or dimidiate, sessile pileoli. 

 When growing on abundant woody matter, as is the case in the 

 specimen in Sowerby's illustration already cited, the fructifica- 

 tion assumes a redder color and replaces its dimidiate, sessile 

 pileus on earth by a reflexed one on the wood. With regard to
