Perithecia scattered, erumpent-superficial, depressed-hemispheri- 

 cal, about 200 II diam., with a short, nipple-like, black ostiolum. Asci 

 subcylindrical, mostly curved at least when young, attenuated above,

On foliage of Sequoia gigantea, California. 



We have drawn these characters from a reexamination of the orig- 

 inal specc. and find the sporidia shorter than stated in the original 

 description. In some specc. paraphyses were seen, but they were very 

 rare and very evanescent. 



FAMILY. SPHJIRELLOIDEJ:. 



Perithecia membranaceous, small, mostly perforated with a simple 

 pore at the apex, without any distinct ostiolum, at first covered by the 

 epidermis, finally more or less erumpent or even superficial. Asci 

 mostly fasciculate. Paraphyses wanting or obscure.
