314. A. discopus Lev. Shining white. Pileus conical, obtuse, 

 mealy-pulverulent. Stem very tender, mealy-pulverulent, inserted 

 with a small hairy bulb. Gills adnate, few, very distant, plicose. 



Very small. Clearly distinct from A. tenerrimus in the gills. 

 On twigs. 



Name Stoxos, a disc ; TTOUS, a foot. From the stem set on a disc. Ltveill.

315. A. sacchariferus B. & Br. Whitish, everywhere beset 

 with shining granules. Pileus 4 mm. (2 lin.) broad, wholly hemi- 

 spherical. Stem short, 4 mm. (2 lin.) long, filiform, fixed at the 

 base by a few flocci. Gills arcuato-decurrent, 8-9, very distant, 

 rather thick, their margin and even the surface granulated. 



Allied to A. tenerrimus, which has crystalline particles on the pileus, but the 

 gills are free and ventricose.

316. A. pterigenus Fr. Wholly beautiful rose-colour. Pileus 

 6 mm. (3 lin.) broad, 4 mm. (2 lin.) high, very tender, pellucid, 

 globose when young, then oblong, and at length campanulate, 

 always obtuse and at length umbilicate, even except as it appears 

 slightly striate from the translucent gills. Stem at first obso- 

 letely, but when full grown remarkably fistulose, flaccid, smooth, 

 naked, thickened into a bulb and girt with long, strigose, radiat- 

 ing fibrils at the base. Gills few (6-8), adnate, broad, distant, 

 distinct, and without any dimidiate ones intermixed. 



Although always delicate and thin it varies very much in stature ; stem 

 capillary, in choked-up places elongated to 5-7.5 cent. (2-3 in.), sometimes 

 tense and straight, sometimes flexuous ; pileus at the beginning of the size 

 and form of a pin's head. In natural affinity it comes nearest to A. capillaris. 

 Gregarious and often fasciculate. 



On dead fern-stems, &c. Uncommon. Sept.-Nov. 



Var. with lemon-coloured stem, and more crowded gills, on oak-leaves. 

 M.J.B. The gills are occasionally alternate. Usually found by the sides of 

 rivulets. The dead fern-stems, hanging in damp masses, must be lifted up, 

 as it generally grows underneath, and is easily overlooked. Spores ellipsoid, 

 8-9 x 4 mk. K. Namepteris, a species of fern ; gigno, to bear. Growing on 

 fern-stems. Fr. Monogr. i. p. 231. Hym. Eur. p. 152. Icon. t. 85. /. 4.
