HYMENOMYCETES. 



ORDER I.— AGARICINI. 



Genus V. — Cortinarius (cortiua, a veil). Fr. Epicr. p. 255. 



Veil arachnoid, distinct from the cuticle of the ftileus, superficial. 

 Hymenophore continuous with the stem. Gills persistent, arid, 

 changing colour, 'pulverulent with the spores which fall off slowly. 

 Trama fibrillose. Spores globose or oblong, here and there 

 apiculate, somewhat ochraceous on white paper. Growing on 

 the ground in woods, putrefying. Fr. Hy?n. Eur. p. 335. 



The most natural of the genera of Agaricini, but not easily 

 defined by artificial characters. The veil and the gills present 

 the chief marks of distinction. The gills generally become 

 cinnamon-coloured. Very rare or altogether wanting in hot 

 countries, but generally abundant in northern woods. All 

 autumnal. They present a very different appearance in different 

 stages of growth, and in the various stages according as they are 

 moist or dry. It is necessary, therefore, to examine species both 

 in their earlier and later stages. Some FlammulcE resemble 

 them, but can scarcely be confounded with them. 



cium. 



Tribe I. PHLEGMACIUM (4>AeV a j clammy moisture). Par- phkgma- 

 tial veil arachnoid. Pileus equally fleshy, viscous. Stem firm, 

 dry. Fr. Hym. Eur. p. 336. 



f Cliduchii (C. cliduchus. KAeiSoux°?, nkeis, a club ; «x w . to have). Partial 

 veil superior, pendulous in the form of a ring from the apex of the nearly equal 

 or clavate stem. 



* Gills pallid then clay-colour.
