Gregarious. Distinguished by the sulphur-yellow colour 

 of every part, and the strong, penetrating, unpleasant smell. 



Pileus 1-2 in. broad, fleshy, obtuse, at length expanded 

 or depressed with a slight appearance of an umbo, sometimes 

 flexuous and irregular, dirty yellow, or ochraceous-umber, 

 darker in the centre, the margin at first involute and 

 minutely tomentose, the whole clothed with extremely 

 minute .silkiness or squamulae, so as to give it a pulverulent 

 appearance, retaining the impression of the fingers; flesh 

 yellow. Gills subdistant, rounded, flexuous, emarginate or 

 acuto-adnate. Stem 2 in. or more high, 4 lines thick, occa- 

 sionally subbulbous, stuffed, sometimes at length hollow, 

 the surface of the cavity rather slimy, yellow within, 

 furnished at the base occasionally with many rather strong 

 yellow fibrous roots. Odour disagreeable, at first faiina- 

 ceous, then like that of Hemerocallis Jiava. Taste unpleasant
