Perithecia scattered or subgregarious, innate-superficial, ovoid, 

 smooth, at first with a short, cylindrical or compressed ostiolum, black, 

 300-500 /i diam. Asci cylindric-clavate, 90-125 x 10-12 ju, 8-spored. 

 Sporidia biseriate, elongated or oblong, 3-septate, constricted in the 

 middle, greenish-hyaline, 20-26x5-8 fi (sometimes 35 p. long). 



On branches, Bethlehem, Pa. (Schw.). 



The ostiolum is finally deciduous; the perithecium is then rather 

 broadly perforated.

Var. effusa, on decorticated ash limbs, London, Canada (Dear- 

 ness), has the perithecia densely gregarious and effused in patches 

 more or less crowded for .1 cm. or more in extent. Asci and sporidia 

 as in the typical form.

Perithecia subcutaneous, erumpent, cespitose, black, subglobose, 

 papillate, seated on a pulvinate stroma. Asci cylindrical, 8-spored. 

 Sporidia lanceolate, 3-5-septote, cells divided by longitudinal septa, 

 olivaceous, 50x15-18 p.. 



On Ailanthus glandulosa, Aiken, South Carolina (Ravenel). 



Evidently different from C. Ailanthi, Rabh. Sacc. Syll. 3958. ,

The spec, in Herb. Schw. labeled Sphceria stemmatea, Fr., "from 

 Bartrams," is apparently a Phyllosticta or a Septoria, but without 

 fruit; it is, however, different from a spec, of S. stemmatea, Fr., in the 

 same collection from Fries, in having larger perithecia. The Friesian 

 spec, shows the asci very distinctly, but the sporidia are immature and 

 not well defined. The general appearance of this spec, is exactly that 

 of Sphcerella Gaultherice, C. & E. Grev. VII, p. 42. Probably S. 

 Gaultherice and S. brachytheca are both synonyms of S. stemmatea, 

 Fr., but this can not be definitely stated without further observations.
