571. A. firmus Pers. — Pileus 5-7.5 cent. (2-3 in.) broad, brick- Hebeioma. 

 red, fleshy, campaniclate then Jiatte7ied, timbo7iate, the broad um- 

 bo darker, thin at the circumference, even, smooth, viscid. Stem 



5-7.5 cent. (2-3 in.) long, 12 mm. {yi in.) thick, solid, firm, some- 

 ivhat attenuated and commonly da^'ker downwards, clothed 

 throughout with white. Jloccose squamules. Cortina evident^ white. 

 Gills rounded, crowded, 4-6 mm. (2-3 lin.) broad, thin, arid^ clay- 

 colour then ferruginous, unspotted, but white-serrulated at the 

 edge. 



The gills do not distil drops, hence they are unspotted. Odour weak. 



In fir woods. Laxton Park, 1875, &c. Feb., Oct. 



In the letterpress to ' Icones' Fries describes his plant as convex then 

 plane, and notes that the plant of Persoon differs in being campanulate and 

 umbonate. In the fig. of Fries the pileus is at length depressed. The British 

 plant is that of Persoon. Berkeley has gathered a plant referable to this, in 

 which the pileus was at first of a deep brown, changing to tan, and the gills 

 adnate with a minute decurrent tooth. Spores ellipsoid, attenuated at both 

 ends, even, 11-12x5-6 mk. K. '^■^vc\^— firmus, firm. Pers. Ic. descr. t. 5.

572. A. claviceps Fr. — Pileus pallid, co7ivex then expanded, 

 fleshy at the gibbous disc, even, naked. Stem stuffed, equal, 

 everywhere white-mealy, fuscous downwards. Gills emarginate, 

 crowded, arid, pallid. 



Wholly different from A. firmus P. in the smaller stature of all its parts, 

 in the stem being fuscous downwards, in the pallid gills, chiefly however in 

 the pileus being convex then expanded and discoid, in no wise conical then 

 campanulate.

573. A. punctatus Fr. — Pileus 2.5-5 cent. (1-2 in.) broad, 

 fleshy, convex, soon plane, disc obtuse or gibbous, always how- 

 ever darker and viscoso-papillose, at length depressed round the 

 umber centre, like a smooth sugared cake, becoming pale when 

 dry, when young superficially silky rou7id the i7iargin with the 

 whitish fibrillose veil. Stem 5-10 cent. (2-4 in.) long, 4-8 mm. 

 (2-4 lin.) thick, in its earliest stage hollow, equal, here and there 

 flexuous, dry, pallid, white-pruinose at the very apex, otherwise 

 silky-fibrillose with the adpresscd veil. Gills narrowed behind 

 and arcuato-adnate, slightly ventricose, crowded, quite entire, 

 7iarrow, 2-4 mm. (1-2 lin.) broad, plane, pallid.
