its duplex character over the margin of the pileus and partial veil. 
In C. anjractus and C. armillatiis there is developed a firm outer layer, 
which persists until maturity. This zone is very thin, but extends 
completely over the upper part of the fruit body. In C. anfractus 
it becomes consolidated with the cortex. The inner portion of the 
blematogen is much more floccose in character and extends from 
the upper surface of the margin of the pileus, outside the partial veil, 
to the stem. In the other three species, C. cinnamomeus, C. distans, 
and C. lilacinus, the duplex character is not evident, owing perhaps 
to the early wearing away of the surface. The inner floccose zone 
is, however, present in all. 
4. The marginal veil is developed from the ground tissue lying 
between the fundaments of the hymenophore and stem, to which 
are added new elements from the margin of the pileus. The cortina 
is therefore made up of two elements; 1st, the blematogen on the 
outside, which extends from the upper surface of the margin of the 
pileus to the stem; and 2d, the inner threads consisting of the fibers 
of the marginal veil. 
5. One species, C. armillatus seems to possess a protoblem. There 
is evidence of this layer being present in early stages of another species, 
C. anfractus. It is very possible with other methods of fixing and 
preparation, it might be found in all. 
In conclusion, I wish to acknowledge my deep indebtedness to 
Professor G. F. Atkinson for his kind direction and helpful advice.
