Nectria episphaeria (Tode) Fries 

 A blood-red Nectria on Eutypella on beech, collected by Peck at 

 Morehouseville, but unnamed, possesses the essential characters of 

 Nectria episphaeria, but is smaller in every way than 

 the measurements given in the description of the usual form. The 

 perithecia are mostly under 100 p. in diameter; the asci 45 /i, instead 

 of 60 fjL long, and the sporidia 7x4/0,, instead of 9-12 x 4-6 p.. 

 It may stand for the present as var. minor Dearness & House, 

 var. nov. 



Thyronectria Xanthoxyli (Peck) E. & E. 

 On dead branches of X a n t h o x y 1 o n a m e r i c a n u m L. 

 West Troy. C. H. Peck, October 1898 (type). This has been 

 merged by Seaver^' into T. pyrrhochlora (Auers.) Sacc. 

 It has, however, certain distinctive characters, including smaller 

 cespitose perithecia in smaller and less immersed stroma, which 

 makes this disposition of the species open to question. 



Balansia Hypoxylon (Peck) Atkinson^^ 

 On leaves of Spartina Michauxiana Hitchc. Lewis 

 Point, Madison county. H. D. House, August 20, 1918. The 

 ascigerous cells are 360 /x long; the longest asci about 270 jx long; 

 spores nearly as long and .7 fx thick. Doctor Peck collected the 

 type of this species at Sandlake, Rensselaer county, on D a n - 

 thonia spicata (L.) Beauv. 



Claviceps purpurea (Fr.) Tul. 

 Sclerotia on the inflorescence of Spartina alterniflora 

 Loisel., Long Beach, Long Island. H . D. House, October 20, 1923. 

 Some of the sclerotia are over 2 cm long. 



Dothidella caricina Dearness & House, sp. nov. 



Stromata black, covered at first by the blackened epidermis and 

 strongly suggesting a small form of Phyllachora graminis ; .15-1.5 

 mm in length, .15-.4 mm in width, containing one, two or three 

 ascigerous cells, sometimes more (eleven was the largest number 

 observed in a single stroma) ; ostiola black, shining, sulcate, about 

 50 fx in height, and of the same width, rupturing the lower, that is, 

 the outer surface of the leaves and sheaths ; asci narrowly clavate, 

 60-75 ^ 7~8 jx, eight-spored, paraphysate; sporidia hyaline, unisep- 

 tate, partially biseriate, usually nucleate and slightly curved on one 

 side, 11^18 fx long, mostly about 15 x 3 /i.
