leaving the sporangioles seated alone on the wood, barely visible 
without magnification ; sporangioles yellowish-brown, very numer- 
ous, crowded, circular, flattened above and below, barely 0.25 mm. 
in diameter, even or slightly creased under high magnification ; 
spores subglobose, hyaline, thick-walled, 4~7 » long, 3-6 y wide.

3. Granularia rudis Peck sp. nov. 
Peridia hemispherical or subglobose, sessile; outer covering 
thin, smooth, fragile when dry, cellular, rather gelatinous when 
Moist, yellowish-brown with a faint greenish tint ; indehiscent or 
the peridial walls gradually breaking away ; sporangioles few, irreg- 
ular, angular or compressed, 2-2.3 mm, in diameter, blackish or 
greenish tinted; spores broadly elliptic or subglobose, hyaline, 
7-9 long, 6-8 w broad. (PL. 17. f. 21-23.) 
On decaying wood. 
Cauirornia: W. R. Dudley. 
The material from which this species is described is very scanty, 
but the specific features are so individual, and they differ so much 
from any known species of Granularia that it has been decided to 
include it in the present revision. It differs from all known species 
in the gelatinous cellular and greenish texture of the peridium, and 
in the large angular sporangioles, only a few being contained in 
€ach peridium,
