12 FUNGUS-FLORA. 



being sessile or extended behind ; at first sessile resnpinate, 

 soon shell-shaped, dimidiate, obovate, at length broadly ex- 

 panded, undulately lobed, often imbricated. Every part 

 dingy yellow. Size very variable, about l in. long. Surface 

 minutely pubescent, then glabrous, slightly rivulose. Flesh 

 equal, but thin. Gills decurrent to the base, anastomosing 

 behind, branched, crowded, crisped, yellow. In a small form 

 the gills radiate from an excentric point. (Fries.) 



Far. fagi, Cooke. 



Gregarious, crisped, pallid upwards, orange beneath ; gills 

 crisped, orange. 



Paxillus panuoides, B. & Br., Ann. Nat. Hist., No. 1961. 



On a beech stump. 



Although described as a distinct species, we fail to detect 

 in the dried specimens, or in the spores, any specific dif- 

 ference from P. panuoides ; only the deeper colour of the 

 gills and different habit being manifest. (Cooke.) 



COKTINAKIUS. Fries. (All figs, on p. 16.) 



Pileus symmetrical, flesh thick or membranaceous ; stem 

 central, flesh continuous with that of the pileus ; veil cob- 

 web-like or silky-fibrillose, not interwoven to form a mem- 

 brane, distinct from the cuticle of the pileus and superficial, 

 not forming a distinct ring on the stem, but frequently 

 remaining as a silky or fibrillose zone ; gills persistent, dry, 

 pulverulent, often violet at first, finally ferruginous or bright 

 cinnamon from the spores. 



Cortinarius, Fries, Epicr., p. 255 ; Cke., Hdbk., p. 236. 



One of the most natural of genera belonging to the 

 Agariciuae, but at the same time difficult to define in words. 

 The most marked features are the cobweb-like or spidery 

 veil and the bright ferruginous spores. The gills are dry 

 and thin, the mode of attachment various, free, sinuate and 

 adnexed, adnate, and sometimes with a decurrent tooth, but 

 rarely truly decurrent. When young, the gills are often 

 more or less tinged with purple or blue, as is also the stem, 

 and in fact in many species every part of the fungus is more 

 or less tinged with purple or blue when young, this colour, 

 however, usually disappearing at maturity.
