574 Ellis and Everhart : New Species of 



Perithecia 2-3 lying side by side in the blackened substance of 

 the bark which is split longitudinally and slightly raised, the papilli- 

 form ostiola being visible in the narrow chinks ; sporules elliptical 

 or slightly obovate, 3 -septate, pale brown, 12-15 x 6-8 /i, on 

 slender pedicels about I 5 ft long.

Septoria megaspora Speg. ? Fung. Arg. Pug. 1, 188 



Kellermannia mittica E. & E. in herb. 



On leaves of Yucca filifera, Monterey, Mexico, March, 1900, 

 and on leaves of Agave Lechngrulle, Peyotes, Mexico, April, 1900 

 (Dr. Wm. Trelease). 



Perithecia scattered, sunk in the substance of the leaf, .5-1 

 mm. diam., raising and throwing off a circular piece off the cuticle 

 directly over them : sporules clavate-cylindrical, hyaline, multi- 

 septate, scarcely constricted, 70-100 x 8-10//, attenuated above 

 to an obtuse point, sessile, fasciculate. 



Differs from Spegazini's description in the multiseptate spores 



and might properly be placed in the genus Phleospora. 



Septoria annua E. & E. 



On partly dead leaves and culms of Poa annua, London, 



Canada, May, 1900 (J. Dearness). 



Perithecia scattered, black, depressed-globose, pierced above, 

 75-110 ft diam.; sporules abundant, filiform, mostly attenuated 

 below, nucleolate, hyaline, 30-40 X 1.5 /A slightly curved. 

 Comes very near 5. tenella C. & E. 



Septoria cylindrica E. & E. 



July, 1878 (J 



Blankenship, no. 78). 



Perithecia hypophyllous, globose, ioo-no/i diam., black, 

 erumpent, scattered on pallid, indefinite spots ; sporules fusoid- 

 cylindrical, moderately curved, 25-35 X 2.5-3^, 3-(pseudo-)sep- 

 tate, nucleate at first. 



Melanconium angustum E. & E. 



On dead hickory limb, Newfield, N. J., Feb., 1900. 



Acervuli minute, raising the epidermis into small pustules, then 

 erumpent, often compressed ; conidia oblong, olive-brown, 2-3- 

 nucleate, straight or nearly so, 12-16 x 4—5.5 /^, narrower and 

 darker than in M. pallidum Pk. t and acervuli smaller.
