98 Forty-fifth Report on the State Museum. 



Pileus 6 to 8 lines broad ; stem about 1 inch long, 1 line thick. 



Thin soil covering rocks. Mount Marcy. August. Yery rare. 

 Not found since 1873. Eemarkable for the discolored edge of 

 the lamellae. 



Omphalia umbellifera X. 



Umbel-bearing Omphalia. 



(Hym. Europ. p. 161. Syl. Fung. vol. V, p. 321.) 



Pileus convex or plane, somewhat obconic, hygrophanous, 

 radiate-striate when moist, whitish or pale-yellow ; lamellae broad, 

 distant, somewhat triangular, white ; stem short, stuffed, becom- 

 ing hollow; spores broadly elliptical, .0003 to .0004 in. long, 

 .0002 to .00025 broad. 



Pileus 4 to 8 lines broad; stem 6 to 10 lines long, .5 line thick, 

 ground or decaying wood. 



Yar. scabriuscula. (Agaricus scabriusculus Pep. 23, p. 85.) 



Plant commonly larger, pileus flocculose-pulverulent, yellow ; 

 lamellae white or pale-yellow, the interspaces venose ; stem hairy - 

 squamulose. 



Decaying wood. Adirondack mountains. 



This is a very variable species. It occurs from June to Sep- 

 tember, and grows on ground largely composed of decomposed 

 vegetable matter or on much decayed ^wood. In this State it 

 seems to be limited in its range to the Adirondack region and 

 there it ascends to the tops of the highest peaks. Its pileus and 

 broad lamellae together have an obconic shape. It is often irreg- 

 ular or misshapen. The stem may be either glabrous, pruinose 

 or hairy-squamulose. Sometimes it is pubescent or villose at the 

 base only. The pileus is either glabrous or silky or flocculose- 

 pulverulent. 



Omphalia Campanella Batsch. 



Bell-shaped Omphalia. 



(Hym. Europ. p. 162. Syl. Fung. vol. V, p. 327.) 



Pileus thin, rather tough, hemispherical or convex, glabrous, 

 umbilicate, hygrophanous, yellow-ferruginous and striatulate 

 when moist, paler when dry ; lamellae moderatety close, arcuate, 

 decurrent, yellowish, the interspaces venose; stem firm, rigid, 

 hollow, brown, often paler at the top, tawny-strigose at the base /
