PLUTEOLUS — ^PHOLIOTA. 209 



On rotten sticks, &c. 



Fragile. Distingnished from P. rettculahis, by the pilens 

 not having raised, anastomosing veins, and in the powdery 



stem. 



PHOLIOTA. Fries, (fig. 10, p. 3.) 



Pileus more or less fleshy ; gills adnate, -with or without 

 a decurrent tooth, or rounded behind and adnexed, tawny or 

 ferruginous at maturity, as are also the spores ; stem central, 

 furnished with a distinct interwoven ring. 



Pholiota, Fries, Syst. Myc., i. p. 24Ci; Cke., Hdbk., p. 140. 



The only genus in the Ochrosporae having the sten t 

 fnmisEed with a persistent, membranous, or interwfiveu 

 Tnore or less spreading ring. In Flanmula, a closely allied 

 genus, the ring, if present, is fibrillose and never forms more 

 than an indistinct silky zone or girdle round the stem. In 

 Co rtina rius. which is also allied, the veil is fibrillose, forming 

 at most a zone round the stem. 



A few species grow on the ground, principally in damp 

 places amongst moss, bat .the majority grow on wood, and 

 are often densely caespitose. The genus includes many very 

 large and brilliantly coloured species.
