PAXILLUS. 



The gluten on the pileus dries especially round the margin into black spots, Gomphidius. 

 or forms a narrow irregular black border. The gills are clothed under a lens 

 with short tomentose hairs. Distinguished from other species by its slender, 

 thin, and delicate habit.

GENUS VII. Paxillus (paxillus, a small stake). Fr. Gen. Paxiiius. 



Hymenom. p. 8. 



Hymenophore continuous with the stem, decurrent. Gills 

 membranaceous, scissile, somewhat branched and here and there 

 anastomosing behind, distinct from 

 tJie hymenophore and readily separ- 

 ating from it. Spores dingy whitish 

 or ferruginous. Fleshy, putrescent, 

 pileus at first with the margin in- 

 volute then continuously and gradu- 

 ally unfolded and dilated, indeter- 

 minate. 



A natural genus, but its extent is 

 not yet properly determined. There 

 are several species of Tricholoma and 

 Clitocybe, which apparently ought to 

 be transferred to it. It is analogous 

 to Boletus in respect of its gills easily 

 separating from the pileus, but to 

 Polyporus in respect of its indefinite 

 growth. Most of the species seem to 

 be edible. Fr. Hym. Eur. p. 400. 



It comprehends two typical sections which are manifestly dis- 

 tinct, the one that which has P. lepista for its type, the other 

 (Tapinia) that which has P. involutus tor its type. The former 

 always grow on the ground, but the Tapinia^ occur both on the 

 ground and on trunks ; the former have the pileus entire, the 

 latter more or less dimidiate, or altogether lateral and sessile. 

 Fr. Monogr. ii. p. 115. 



Trib. I. LEPISTA (P. lepista}. Pileus entire, central. Spores dingy, only 

 in P. panceolus with a tendency to ferruginous. 



Trib. II. TAPINIA (Tan-etvow, to depress). Pileus commonly excentric or 

 resupinate. Spores ferruginous.
