from the leaves of the host, turbinate, greenish, becoming almost 

 black in dried material; hymenium plane or nearly so, lighter 

 than the outside of the apothecium, the substance of the apothe- 

 cium pale olivaceous-green when teased out and viewed by 

 transmitted light; asci clavate, reaching a length of 100-135 /x 

 and a diameter of 25-30 m, the contents greenish; spores irregu- 

 larly 2-3-seriate, fusoid to fusiform, the lower end more pointed 

 than the upper, densely filled with granules and slightly yellowish- 

 green, simple, about 8-9 X 25-28 m, smooth, or very minutely 

 roughened; paraphyses filiform, scarcely enlarged above.

According to the late J. R. Weir this fungus is the cause of a 

 very destructive blight. Omhrophila thujina Peck apparently 

 differs only in the smaller size of the spores. The type has been 

 examined.

Apothecia scattered, stipitate, at first closed, gradually

 outside of the apothecium; asci clavate, reaching a length of

 2-seriate, fusoid, or fusiform, often with two distinct oil-drops, or 

 granular, apparently greenish when young, usually hyaline when 

 mature, often minutely roughened or smooth, simple, 7-8 X 

 20-38 /x; paraphyses slender, rather abruptly enlarged above 

 and surrounded with a greenish-yellow substance.
