Densely gregarious. Peritliecia ovate, 150-200x110-120 fi, 

 dark I'ed, smooth or nearly so, not collapsing. Asci (p. sp.) about 

 35 /J. long, cylindrical, evanescent. Sporidia uniseriate, oblong-ellip- 

 tical, hyaline, obtuse at the ends, uniseptate and slightly constricted, 

 5-6 x2| /^. This has the general appearance of iV". ditissima, TuL, 

 but besides the more regularly shaped perithecia the sporidia are 

 much smaller. The asci are with difficulty seen so that this might be 

 taken for a stylosporous fungus only from the fact that here and there 

 series of eight sporidia lying end to end indicate the presence of asci.

Cespitose. Perithecia of medium size, | mm. diam., globose, 

 minutely furfuraceous, of a brick-red color, sometimes collapsing, with 

 a darker colored papilliform ostiolum. Asci subcylindrical, 100-115 x 

 12 a. Sporidia 15x5-6 /i, ol)long-elliptical, uniseptate. 



This spCL'ies was found at Newfield some years ago on outer bark 

 of living quince trees. The Newfield specimens agree with authentic 

 specimens from Plowright in all respects, only the sporidia are a little 

 smaller (15x5-6 /i). In Plowright's specimens they are 18-22 x 

 6-7 p. and subinequilateral. The Newfield specimens were immature, 

 the asci being mostly filled with granular matter. What appears to 

 lie the same was also sent by Dr. Macoun from British Columbia, on 

 bark of maple.

Perithecia very minute, scarcely visible to the naked eye, solitary 

 or 2-3 together, conic-globose, slightly depressed at the apex, purplish- 

 red. Asci oblong-elliptical, 60-80x10-14 [i, with eight biseriate, 

 oblong, two-celled, hyaline sporidia, slightly constricted in the middle 

 and about 11x7 fi, becoming at length subfuscous.
