Perithecia 5-15 in a pustule, circinating in a sulphur-yellow 

 stroma formed of the altered substance of the bark, depressed-globose, 

 J mm. or a little more in diani., contracted into slender, convergent 

 necks, with their papilliform, minute, black ostiola erumpent mostly 

 around the margin of a small, flat, circular, yellowish disk which 

 pierces the epidermis, but scarcely rises above it. Asci (p. sp.) 70-75 

 X 12-15 /<, 8-spored, Sporidia biseriate, fusoid-oblong, uniseptate, 

 each cell nucleate, hyaline, 15-20 x 5-7 [x, with an obscure apiculus at 

 each end. 



On bark of dead Carpimis, London, Canada (Dearness). 



The yellow color of the stroma is sometimes very distinct, and 

 again scarcely perceptible. It is doubtful whether this is more than a 

 form of D. sulphurea^ Fckl.

Perithecia collected in valsoid groups lightly covered by the 

 pustulate, superficial layer of the inner bark, ovate-globose, 12-20 in 

 a stroma. Ostiola erumpent togethei-, but not confluent, about \ mm. 

 long, obtusely pointed and mostly smooth at the apex, black and 

 brittle. Asci subfusoid, 8-spored, p. sp. 40-45x8-9 p.. Sporidia 

 inordinate or subbiseriate, cylindric-fusoid, very slightly curved, uni- 

 septate and slightly constricted in the middle, with a short appendage 

 at each end, hyaline, 10 x 3 //.

"Quite covered by the bark, which is merely pierced by the osti- 

 ola surrounded more or less evidently by a black line. Sporidia fusi- 

 form, sometimes sigmoid, uniseptate, 45-50 n long." 



On willow. South Carolina (Berk.) 



Cooke, in the Valsei of the U. S., doubts whether this is distinct 

 from D. tessera, (Fr.), as the slight appendages may have been over- 

 looked.
