Lisiiiicolous. Perithecia scattered, included in an elliptical, ele-- 

 \ated, gray or black tubercle pierced by the short, incolispicuou!-^ 

 ostiolum. Asci cylindrical, 8-spored. Sporidia tiniseriate, elliptical, 

 constricted in the middle, 3-septate, with 1-2 loiigittidilial septa, bright

On decorticated Acacia, California (Harknessj. 



We have seen no specc. of Th. personatum, Cke. & Hark., but 

 the description agrees in all respects with that of Th. liijidum. 



Til. Canad^nse, E. & E. (in Herb.) 



Perithecia scattered or gregarious, on the more or less bleached 

 surface of the wood, minute (| mm. or less), covered by a thin, oblong

 and muriform, hyaline, 20-27 x 10-13 fi. 



On old (spruce)? logs. Lake Nipigon, Ontario, Caftada (Macoun). 



Outwardly this much resembles Th. lividum^ but the shield is 

 thinner. Perithecia much smaller, sporidia larger and hyaline.
