GUIDE TO THE MODELS OF FUNGI. 



Coprittus, but merely become moist or mucid and putrefy ; the spores 

 also differ in being ferruginous, and not black. The species, owing 

 to their yellowish-ferruginous colours, are sometimes taken for 

 Corlinarii, but they never have an arachnoid veil and commonly 

 grow on dung or dungy places like Coprinus.

GEAUS 2V.—C0RTIAARIUS Fr. 



The genus Cortinarius is distinguished 

 from other genera of the Agaricinece by an 

 arachnoid veil (cotiina), by dry, persistent 

 gills, which usuall}' change colour to cinna- 

 mon, and by ferruginous spores. The 

 species appear of various colours at dif- 

 ferent periods of growth and according as 

 they are wet or dry ; all are terrestrial 

 and autumnal. They are frequently confounded with species of 

 Pholiota and Hebcloma, but these do not possess a cortina. 



C. violaceus Yr. is looked upon as esculent. The Rev M. J. 

 Berkeley has recorded an undoubted case of poisoning by C. bolaris 

 Fr. : the results were alarming, but not fatal ; the symptoms were great 

 oppression of the chest and profuse perspiration. Two days afte. 

 eating the fungus the salivary glands re- 

 mained enlarged and tender. There are 

 184 British species o{ Cortinarius, of which 

 eleven arc represented by models. 



The genus Cortinarius is divided into 

 sub-genera. 



Sub-genus i. Plilcgmacium. — Veil 

 partial ; pileus fleshy, viscid ; sicin firm, 

 dry. There are fifty-two British species 

 of Plilrginaciiint, of which three are repre- 

 sented by models.

73. Cortinarius varius 

 fleshy, briglit Icrruginous-tawn}' or ycllow- 

 tawn}', very obtuse, slightly viscid, smooth, 

 parts of the cortina attached to the margin ; flesh white ; gills 

 sinuate, thin, somewhat crowded, violaceous-purplish or dark blue,.
