and from below because of the protuberance that they cause. At maturity 

 the clypeus falls away, the contents of the perithecia drop out, and a hol- 

 low "poc-mark" cavity remains. The variability of the conidia is quite 

 remarkable. 



Trabutia portoricensis, sp. nov. — Spots approximately circular, 

 densely set with perithecia, area of young spots not at all or but 

 slightly discolored, tissue of old spots dead, tan colored. Peri- 

 thecia conspicuous above, due to the shining black clypeus, from 

 below by the protuberance which they cause. Perithecia opening 

 epiphyllous, clypeus black, 80-95 /jl in diameter. Ostiole central, 

 10-15 M * n diameter. Perithecium central in the mesophyll. Asci 

 irregular, thin-walled, 8-spored, inordinate, 68X17/1- Paraphyses 

 many; spores filiform, oblong, obtuse, 24X7 m> continuous, hyaline.

Trabutiella, gen. nov. — Similar to Trabutia, but with the asci 

 16-spored. Similar to Ditopella, but distinguished from it by its 

 clypeus. Type of genus the following. 



Trabutiella cordiae, sp, nov. — Spots when young but slightly 

 discolored; later the tissue dies and the spots are tan colored, or 



remain
