carbonaceous, at length depressed, ostiolum minute ; asci clavate, 

 loo-iiox i8 IJ; attenuated below, rounded at the apex, surrounded 

 by numerous filiform paraphyses, 8-spored : Sporidia uniseriate or 

 biseriate, fusoid cylindrical, curved, 26-32 x 6-7 p., triseptate and 

 constricted at the septa, greenish hyaline." According to Niessl, the 

 pycnidial stage is Hendersonia Fiedlc^ri Rabenhorst. On dead 

 branches of Cornus, associated with DidymosplhTJ^ia obHtescens 

 (B. & Br.) Sacc. Feltgen reports this species as occurring in Lux- 

 emburg upon Cornus, Ligustrjim viilgare, and Ulex Eiiropccus. He 

 describes the perithecia as sunken in the matrix up to their papilliform 

 ostioli and the measurements as follows : Asci 106 - 120 x 15 - 18 « ; 

 sporidia 24-26 x 6 /^, hyaline. New to the United States.

 garious, but not crowded, large, ovate globose, clothed mostly at the 

 base with long, brown, bristle-like, septate hairs which are 6 ji in diam- 

 eter, simple or branched, straight or reflexed and flexuous at the tips, 

 covered with a persistent grayish white tomentum, all excepting the 

 protruding papilliform ostiolum which is bare. Inner substance of the 

 perithecia when crushed upon the slide pale greenish-yellow (f^avo- 

 virescent). Asci straight or curved, oblong sub-fusoid or arcuate, 

 with an occasional shining oil drop in the rounded, hyaline apex, 100 

 X 10- 12 //. Sporidia imperfectly biseriate or fasciculate, abruptly bent 

 at the lower fourth, at times straighter and flexuous in the middle, con- 

 tinuous, hyaline, 40 x 5 fJ-. The sporidia are at times furnished with a 

 short (about 6 fx) acute hyaline tip, at one or both ends, which append- 

 ages however are usually absent or indistinct. These appendages are 

 mostly seen in young sporidia and may become absorbed with age.
