upon the subject, it would be useless to remove it to any other equally 

 uncertain neighbourhood.

On fern-stems, leaves, sticks, &c., in v/oods. Aug. — Nov. Common. 

 — Pileus an inch or more broad and high, obtuse, sometimes umbilicate, 

 cinereous-yellow, but also occasionally, according to Fries, white, bkiish 

 or rufous, submeuibranaceous, the margin striate and toothed ; epider- 

 mis viscid ; when moist easily tearing otf. Gills arcuato-adnate, subde- 

 current, partaking of the colour of the pileus. Stem 3 — 4 inches high, 

 about 1 line thick, full yellow, viscid, smooth, tomentose at the base. 



* 9. Dry: j^Heics more or -less depressed ; gills decurrent. 



160. A, caniptophyllus. Berk, {elhow-gilled Agaric); pileus 

 dark-brown, margin deeply striate grey, gills distant wliite 

 ascending then suddenly decurrent, stem minutely pubescent, 

 the base radiato-strigose. 



On sticks, &c. Aug. — Oct. Margate. — Solitary or only subgre- 

 garious. Pileus h an inch broad, dry, convex, obtuse, subhemisphaerical, 

 smooth. Gills rather distant, at first adnate, nearly plane, then ascend- 

 ing and suddenly decurrent, though, as far as I have observed, there is 

 no absolute depression but only a flattening of the centre of the pileus. 

 Stem 2 inches or more high, not a line thick, subflexuous, somewhat 

 rigid, minutely fistulose with a few white fibres ; under a lens minutely 

 but beautifully pubescent, the base radiato-strigose ; at first yellow, 

 when full-grown pale above, pale rufescent below. — This species does 

 not agree with any described by Fries. Of those with which its affinity 

 is evident, 47 — 51 have the gills more or less coloured, 52 has a white 

 stem and a variegated campanulate pileus, 53 has a pubescent pileus, 

 and 54 has evidently a very difierent habit. It seems to come the 

 nearest to the two last. There are besides four supposed species 

 described in a note, but neither does it seem identical with any of 

 these. 



161. A. corticola, Bull, (bai^k Agaric); small, pileus thin 

 hemisphserical then umbilicate striate, gills uncinato-decurrent, 

 stem minutely pulverulent short incurved. Pers. Syn. p. 394.

Trunks of trees, dead bark, &c. Oct. and during the whole v>'inter. 

 Common. — Gregarious. Pileus I — 3 lines broad, hemisphcerical, in 

 general obtuse, but sometimes slightly papillose, rarely umbilicate; 

 umber, white, cinereous, lilac and according to Fries, flesh-coloured, 

 rufous, bluish, &c. ; Jiesh rather thick in proportion. Gills variously 

 adnato-uncinate or subdecurrent, partaking more or less of the colour
