germinating sorus from which the culture drop had receded put forth 
long hyaline somewhat sinuous filaments, the branches (lateral) of which 
resembled promycelia and bore globules at their tips. The after devel- 
opment of the sporidia I have not seen. ‘The structure of the mature 
sorus of this fungus seems to approximate it to the genus Burrillia, estab- 
lished by Dr. Setchell for a species growing in the leaves of Sagittaria’ 
It may be characterized as follows: 
Burrillia globulifera, n. sp. Sori globose to elliptical, dark brown 
or black, surface uneven, 250-450 » in diameter. Spores one to three 
deep on the surface of the sorus, dark brown, closely compacted, irreg- 
ularly polyhedral, 6-9 » in diameter. Sorus beneath the spores com- 
posed of dark brown pseudoparenchyma limited within by a narrow 
layer of hyphe enclosing a central cavity. Development of the sorus 
centripetal. Germination of the spores in the sorus. Promycelia about 
2m in diameter, 30-80 long, brownish, studded with numerous 
minute rounded prominences. Sporidia 4 to 8 or more, terminal, 
whorled, cylindrical, 12-18 x 3 yw, formed in a globule of fluid.
