shows the core in situ in the peridium with the ligaments binding 

 them together. The gleba has been dissipated. Also a figure of the 

 core separate.

MESOPHELLIA PACHYTHRIX. This also may be Meso- 

 phellia arenaria, but the type (all that is known) has capillitium of a 

 different color, much coarser, being compared in color and texture to 

 the fiber of the outer shell of a cocoanut. The spores also appear 

 minutely waited. It is only known from one collection at Kew, 

 called Diploderma pachythrix, by Cooke. 



MESOPHELLIA CASTANEA, FROM C. C. BRITTLEBANK, 

 AUSTRALIA (Fig. 912). Peridium of thick, hard, woody tissue. 

 Surface smooth, pale. Gleba pale pinkish color. Capillitium slender, 

 matted, subhyaline threads about 3 mic. in diameter. Spores elliptical, 

 5 x 10 mic. smooth, subhyaline. Core hard, woody, not attached to 

 the peridium by ligaments. 



The species of Mesophellia hitherto known all belong to the 

 same group with greenish gleba, thin endoperidium, and core at- 

 tached by ligaments. This specimen from C. C. Brittlebank, Mel- 



Fig 912 



bourne (No. 19) differs in several respects, the gleba color, the free 

 core, and the thick, uniform, hard peridium. If the specimen ever had 

 an outer peridium no trace remains. Excepting as to color, it is 

 about the size and appearance of an Italian chestnut. Our figure 

 (912) shows an outer view, a section with the core and gleba in situ, 

 and the core separate.
