XLIV. CORTINARIUS Fr. 

 (From the cortina or veil.} 



Veil single, partially double or double. When single there is 

 only an arachnoid cortina extending from the margin of the pileus to 

 the stem, on the latter of which it often forms a more or less perfect 

 fibrillose zone. When partially double the pileus and stem are more 

 or less fibrous and the arachnoid cortina distinct. When double the 

 whole plant is enveloped in infancy in a veil of gluten from which 

 the arachnoid cortina is distinct. Hymenophore continuous with the 

 stem. Pileus more or less fleshy. Stein central, more or less 

 viscid, annulate from the veil or fibrillose-zoned from the cortina; 

 annulus and zone often evanescent. Gills usually adnate, but some- 

 times adnexed, free or sinuate with a decurrent tooth, membranous, 

 persistent, arid, at first often purple or blue changing to cinnamon 

 from the spores. Spores the colour of iron-rust, rusty-ochre, 

 somewhat ochreous or pale or dark cinnamon. 



The species are variable in size and changeable in colour, purple 

 and blue being common in infancy ; they present a different appear- 

 ance in different stages of growth and according as they are moist or 

 dry ; young as well as mature examples must therefore be studied. 

 All are terrestrial except 1140, which sometimes grows on wood. 



Some species of Pholiota and Flammula somewhat resemble the
