coarser hyphae; globose organs of proteid reaction, 6-15 и 
in diameter, with shriveled or wrinkled surface, are scattered 
throughout the fructification; hymenium composed of gran- 
ule-incrusted hyphal systems and of presumable basidia 
buried among the incrusted hyphae; such basidia-like bodies 
clavate, 60-100 15-20 д, yellow in KHO preparations, simple, 
none seen bearing sterigmata; detached spores hyaline, even, 
18-27 x 12-21 y. 
Fructifications 2-5 mm. in diameter, becoming up to 3 cm. 
long by confluence. 
On bark of frondose trees. South Carolina to Louisiana, 
West Indies, and Mexico to Colombia. 
This species may be recognized by its pulverulent, egg- 
yellow, orbicular fruetifieations which are white within and 
contain so much granular matter as to render other details of 
internal structure obscure and difficult of determination. This 
granular matter holds together so as to show that it is in- 
erusting matter upon very tenuous, nonstaining hyphal fila- 
ments. While I do not doubt that the large, yellow, clavate 
organs near the hymenial surface but buried in the granular 
matter are immature basidia, still I have not demonstrated 
their sterigmata in the preparations of any of the collections 
which have been examined up to the present. The globose 
organs show distinctly in stained preparations which have been 
heated in dilute HCl to free them of the crystalline matter.
