hyphae were in this case so closely packed that it was impossible 
to trace their origin. 
The contents of the cells are very similar to those of Pholiota. 
The large cells have a very thin peripheral layer of cytoplasm 
which contains a large number of small very deeply staining 
granules which may be very minute crystals. Larger crystals 
are very abundant, many of the cells containing twenty-five or 
thirty. They vary from the smallest size determinable to those 
which are one fourth of the diameter of the cell. They take a 
bright red color in the triple stain and are octahedrons in the 
majority of cases but a few appear to have more faces. Because 
of the numerous dark staining bodies, it was frequently impossi¬ 
ble to differentiate the nuclei but in the cells where there were 
very few if any crystals or granules two nuclei were found. The 
large cells have wide pits in their walls through which it is easy 
to trace a protoplasmic strand. In a few cases the pore is so 
large that it is possible to trace a connection not only between 
the peripheral layers of cytoplasm but also between the central 
vacuoles. The protoplasmic granules frequently accumulate 
around these pores in large numbers but the convex plates de¬ 
scribed above are not formed. The slender hyphae are filled 
with a finely granular cytoplasm without any crystals or large 
granules. The cells are regularly binucleated. The convex 
plates are always present at their cross walls. 
Dictyophora duplicata. Ed. Fisch. (Fig. 22). 
The mycelial strands of Dictyophora duplicata were collected 
from the beds of mulch around the base of young trees on the 
University drive. By loosening the soil thoroughly large masses 
of the strands were obtained still in connection with young car¬ 
pophores. The strands are fine and delicate with numerous ir¬ 
regular swellings. They branch frequently and the branches 
sometimes anastomose forming a very loose network. 
The structure of the strands is decidedly different from the 
types already described. The very center of the strand is occu¬ 
pied by a few large hyphae which twine about each other 
slightly. They are formed of very long cells which have lost all 
of their contents and their walls are slightly gelatinized.
