§ Stem glabrous. 69-78. 
§§ Stem floccose or pulverulent at first. 79-92. 
*** Veil formed of white meal or hyaline vesicles (not 
glistening and micaceous). 93-101. 
Section V. 
Volva and ring absent. P ileus covered with glistening , 
micaceous particles when young. 1 02-1 10. 
(It is uncertain as to whether traces of a veil are in reality 
present on the pileus of the species constituting the present 
section. The glistening particles of oxalate of lime are 
washed away in rainy weather, leaving the pileus naked.) 
* Gills attached to the stem. 102-106. 
** Gills free. 107-110. 
Section VI. 
Volva , ring , and veil entirely absent ; flesh exceedingly thin , 
and the pileus soon becomes radially fissured or split along the 
lines of the gills ; furfur ac eons or scurfy , or glabrous. t 11-165. 
(The leading character of the present section consists 
in the radial splitting of the pileus along the lines of the 
back of the gills during the expansion of the pileus. In all 
the previous sections, the radial splitting of the pileus takes 
place along the lines of striation, which are situated between 
the gills. The furfuraceous or scurfy appearance is not due 
to the presence of a veil, but is caused by the cells of the 
thin flesh which are torn apart, and project outwards when 
the splitting takes place. In those species where the flesh 
of the pileus is reduced to a mere film, the surface remains 
glabrous after splitting.) 
* Pileus more or less furfuraceous or scurfy, m-131. 
f Gills attached to the stem, m-120. 
§ Pileus white, m-113. 
§§ Pileus coloured. 1 14- 120.
