 PSEUDOVALSA SMITHII E. & E. n. Sp. 



Perithecia 4-8 together, ovate, about Y^ mm. dia., connate 

 so as to form a sub-hemispherical tubercle i-i>^ mm. dia., 

 and crowned in the center with the tuft of short ostiola which 

 is finally deciduous, leaving the stroma perforated. These 

 stromata are gregarious or sub-confluent and appear to have 

 been at first covered by the epidermis, but, in the specimens 

 examined, this had entirely disappeared, leaving the stromata 

 superficial. Asci not seen. Sporidia fusoid, slightly curved, 

 deep brown, almost opake, 52-62 X 10-14, u, 3-septate, the two 

 end cells small and paler. No appendages were visible but 

 these may have disappeared. 



Ps. hicornis (Cke.) differs in its separate (not connate) peri- 

 thecia. The sporidia are much like those of Ps. sigmoidea 

 (C. & E.), but the habit is different.
