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 ix long, 3-6 jj. 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 ^^- i" diameter, blackish or 

 greenish tinted ; spores broadly elliptic or subglobose, hyaline, 

 7-9 ijL long, 6-8 fji broad. {PL 17./. 21-2J.) 



On decaying wood. 



California : 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 

 each peridium.
