connections exist in C. colwmnatus, they should show as distinctly 
as they do in Mutinus caninus or in Dictyophora duplicata. 
At other places in the preparation the pseudoparenchymatous 
hyphe may happen to lie in the plane of the section. In such 
places, in preparations double-stained with paracarmine and 
safranin, the true relations of the pseudoparenchyma and the 
- tissue of the chambers become clearly shown, as in fig. 8. In 
this figure the wall (f) is shown with the tissue of a chamber 
(2) on one side and with the gelatinous layer of the volva (G) 
on the other. The pseudoparenchyma of the wall has no con- 
nection with either the tissue of the chamber or with that of the 
gelatinous layer of the volva. It has merely taken possession 
of a space between the two. If this figure is compared with 
igs. 11, 12 and 75 of my paper on M: caninus, the contrast 
between the Clathree and the Phallez in the origin of the 
pseudoparenchyma becomes very evident. There is also a 
difference in appearance between the gelatinous tissue in the 
chambers of C. columnatus and that in the chambers of the 
Phalleee which | have seen. In the former there is a very 
marked resemblance to the tissue of the gelatinous layer of the 
Volva. This may be seen also in fig. 8. 
Ed. Fischer’ has asserted that the pseudoparenchyma of the 
Walls of Clathrus is homologous with the hymenial layer, being . 
merely a sterile hymenium. The portion of the section drawn 
n fig. 9 is of great importance in this connection. It represents 
“portion of a column and the adjacent gleba. In the upper 
te of the figure, the basidia of the hymenium (/7) are seen 
Projecting radially outward from the tramal tissue (¢) into a 
chamber of the gleba. The wall (~), consisting of pseudo- 
Parenchymatous hyphe, is situated between the tramal tissue and 
the gelatinous tissue (6) of achamber. The hyphae of the wall 
a slightly laterally inflated. They are not connected with the 
no of the chamber or with the gleba. If the homology put 
sh by Fischer were well-founded, the pseudoparenchyma 
ould have the same connection with the tissue of the chamber
