356. A. gracillimus Weinm. Snow-white. Pileus 4-6 mm. 

 (2-3 lin.) broad, membranaceous, hemispherical, sometimes papil- 

 late, sometimes umbilicate, but never inverted, flocculoss then 

 becoming smooth, sulcate at the sides. Stem 6-12 mm. (3-6 lin.) 

 long, delicately fistulose, bristle-like, soft, inserted by a floccose 

 base. Gills decurrent, thin, somewhat distant, the alternate ones 

 dimidiate. 



It resembles smaller forms of A. fibula, but is always thinner, less tough, 

 withering, wholly shining white, and somewhat flocculose when, young. In 

 many particulars it agrees with A. stellatus, but is thinner, and is certainly 

 distinct in the form of the pileus, which is at first floccose, and in the thin gills. 



In marshy ground on decaying stems. Rare. Aug.

** INTEGRELLI. Gills fold-like, narrow. 



358. A. integrellus Pers. Wholly white. Pileus 4-6 mm. 

 (2-3 lin.) broad, membranaceous, conical when young, soon 

 hemispherical, most frequently irregularly shaped, when flattened 

 12 mm. (Yz in.) broad and depressed at the disc, striate at the 

 margin. Stem as much as 2.5 cent, (i in.) long, delicately fistu- 

 lose, thin but slightly firm, pilose downwards and adnate often 

 with a small villous bulb at the base. Gills decurrent, narrow, 

 in the form of folds, distant, commonly disappearing short of the 

 margin of the pileus, equal or branched, acute at the edge. 



The stem is incurved when growing on wood. The gills are equal or 

 branched as in Cantharelli, but with an acute edge. Small, commonly fas- 

 ciculate (especially on wood), fragile, changeable in form. 



In shady places, on decayed sticks, &c. Uncommon. Oct- 



Nov.
