Nectria dematiosa, Schio. Dead branches of mulberry. Morus aba. 

 Charlton. July. 



Xylaria bulbosa, B. & Br. Ground under tamarack and arbor- 

 vitse trees. Manlius. Aug. 



Hypoxylon Blakei, B. & 0, Dead trunks of willows, Buffalo. Clin- 

 ton. Center. June. This scarcely differs from H. Morsei except in 

 its spores which are a little smaller than in that species. 



Eutypa subtecta, Fr. Dead trunks and branches of poplar, Popu- 

 lus tremuloides. Center. Sept. 



Diatrype quadrata, Schio, Bark of oak, beech, etc. Buffalo. Clin- 

 ton. Sandlake and North Greenbush. This is Diatrype obem B, & 

 C. in Haveners Exsiec. Fung, Fasc, IV, No. 47. It bursts forth from 

 the bark of various deciduous trees and assumes a great variety of 

 aspects, being crowded, scattered or seriately arranged and forming 

 either large or small pustules. Schweinitz's description of it is so 

 defective that it is not surprising that several synonyms have been 

 made. 



Diatrype strumella, Fr. Dead stems of flowering currant, Ribes 

 florida. Albany. May. 



Diatrype nigrospora, n. sp. Stroma small, thin, orbicular, pustulate, 

 blackish or black, elevating the epidermis and stellately or transversely 

 rupturing it ; perithecia few, generally 6-12, sunk to the wood and 

 covered above by the stroma; ostiola slightly prominent, piercing the 

 subcinereous or blackish disk; asci subcylindrical, 8-spored; spores 

 crowded or biseriate, oblong elliptical, obtuse; generally slightly curved, 

 at first pale, then colored, uniseptate, .00065 in. long, .00032 in. broad, 

 each cell containing a large nucleus. Dead branches of birch, Betula 

 lutea. Quaker Street. June. This is related to such species as D. 

 moroides, D. cincta and D. wthiops. 



Melogramma gyrosum Schio Dead bark. Silver Creek, Chautau- 

 qua county. Clinton. 



Valsa Carpini, Pers. Dead bark of water beech, Carpinus Americana. 

 North Greenbush. May. 



Valsa aurea FcJcl. Dead branches of water beech. North Greenbush. 

 May. This species is well marked by the small reddish or yellowish 

 disk and the simple ovate-elliptical spores which are about .0008 in. 

 long and .00035 in. broad. 



Valsa paucispora, n. sp. Pustules covered by the slightly elevated 

 epidermis which is at length ruptured; perithecia, 2-5, seited on the 

 inner bark; ostiola short, black, piercing the miuute pallid disk, even 

 or rarely slightly radiate-sulcate ; asci short, .0025 in. to .0028 in. 

 long, subcylindrical, tetrasporous ; spores simple, uniseriate, nearly 

 colorless, ovate-elliptical, .0006 in. long to .0008 in. long, .0004 in. 

 to .00045 in. broad. Dead alder twigs. North Greenbush. May. 

 This is closely related to the preceding species from which it may be 

 separated by its paler disk, shorter four-spored asci and uniseriate 

 spores. 



Valsa compta, Tul. Dead branches of beech, Fagus ferrnginea' 

 Quaker Street. June. In our specimens the spores are ovate or 

 oblong-elliptical, colorless, .0007 in. to .0009 in. in length. 



Valsa prunicola, n. sp. Pustules scattered, slightly prominent, 

 piercing the epidermis or rupturing it transversely ; perithecia 10-12, 

 fA^sem. Doc. No. 127.] 5
