CLAVIS AGARICINORUM. 211 



Subgenus 20. Hebeloma, Fr. Syst. Myc. vol. i. p. 249 ; with which 

 I include liioajbe, Fr. Monogr. Hymen. Suec. vol. i. p. 334 (Plate III. 

 fig. 20). — Spores for the most part clay-coloured, or in Inocybe feiTU- 

 gineo-fuscous ; veil of a different texture from the pellicle of the pileus, 

 or in Iiioci/be homogeneous with the fibres of the pileus ; pileus fleshy, 

 pelliculose, damp, subviscous, or (in Inocybe) fibrous ; stem confluent 

 and homogeneous with the hymenophorum, fleshy-fibrous, ringless ; 

 gills sinuato-adnate. — Hab. All terrestrial. 



All the species are gregarious, and many so similar in appearance as 

 to be with difficulty distinguished from each other. Some arc scent- 

 less, several smell like rotten pears, and many have a disgusting odour 

 and are poisonous ; none are esculent. Fries, in his ' Monographia Hy- 

 menomycetum Sueciae,' has introduced a new subgenus after Hebeloma, 

 which he names Inocybe, distinguished by the pileus being silky-fbrous, 

 and having a few other unimportant characters ; but I do not see how 

 such a subgenus can stand, unless, indeed, a similar corresponding 

 subgenus be founded after Triclioloma, Entoloma, and HypJioIoma, for 

 all these subgenera have numerous species exactly corresponding with 

 the silky pileus, etc. of Inocybe. I therefore prefer to keep to his old 

 views as expressed in the ' Epicrisis,' and keep Inocybe as a sec- 

 tion of Hebeloma. Hebeloma corresponds with Triclioloma, Plate I, 

 fig. 4, Entoloma, Plate II. fig. 13, Hypholoma, Plate IV. fig. 29, 

 and Pan/solus, Plate V. fig. 33. The species figured is Agaricus 

 (Hebeloma) fastibilis, Fr. A very common species, closely allied to A. 

 crustiiUnoformis, Bull. Spores -0004" x -0003". 



Subgenus 21. Flammula, Fr. Syst. Myc. vol. i. p. 250 (Plate III. 

 fig. 21). — Spores in most species purely fermgineous, occasionally 

 approaching yellow ochre, always bright in colour ; veil filamentous, 

 often obsolete ; pileus fleshy, and, as the subgenus is at present con- 

 stituted, very variable. It may be, — 1, covered with an inseparable 

 and fibriilose cuticle ; 2, covered with a more 'or less viscid and se- 

 parable cuticle; 3, moist, and with no separable cuticle; 4, neither 

 pelliculose nor viscid, and broken up more or less into scales or fibrils ; 

 stem fleshy, fibrous, confluent, and homogeneous with the hymeno- 

 phorum ; gills adnate, acutely adnate, or decurrent. — Hab. On the 

 ground or on wood. 



Fries says the natural affinity of Flammula is with PhoUota, 

 Plate III. fig. 19, but I consider all true Plammnlce should correspond
