Additional Species. 



Leptosphaeria folliculata Ell. & Evht. var. oxyspora n. 

 var. On Carex gracillima. Price Co. Sept. 9, 1911. Differs 

 from the type in the somewhat narrower asei {ca. 50x8/*) and 

 especially in the triseptate acute ascopores (ca. 15x3^.). On 

 the comparatively narrow leaves of this host the perithecia are 

 borne on dead apical areas at the bases of which there is often 

 evidence of primary spotting and confluence. I am indebted to 

 Dr. R. A. Harper for comparison of this with the type in the 

 Ellis herbarium at the New York Botanical Garden. It is not 

 unlikely that sufficient material would connect these forms with 

 L. caricicola Fautr. and L. caricina Schroet. 



Phyllosticta livida Ell. & Evht. On Quercus macrocarpa, 

 Millston, Jackson Co. In these specimens the pyenidia are hy- 

 pophyllous. If they really represent this species the fungus 

 has a wide distribution in the U. S. previous collections being 

 reported from California and Florida. 



Phyllosticta liatridis n. sp. Spots round, white or sordid, 

 arid, 1-2 mm. in diameter, usually surrounded by a broad black 

 border; pyenidia epiphyllous, prominent, black, about 65/*; 

 sporules hyaline, oblong, 2-4 nucleolate, about 10x4/x. On Lia- 

 tris spicata, Gaslyn, Burnett Co. Aug. 1, 1911. This can hardly 

 be Phoma minutissima Cke. as that species is described. 



Diplodia uvulariae ii. sp. Spots oval to orbicular, white, 

 thin and arid, usually with a ferruginous border, 8-15x5-10mm. ; 

 pyenidia mostly epiphyllous, scattered, black, globose, 100-150/*; 

 sporules elliptical to ovate, brown, uniseptate, 12-20x6-7/x. On 

 Vvularia (Oakesia) scssilifolia Spooner, Aug. 15, 1911 (type) 

 and Gaslyn. What is probably imperfect material of this spe- 

 cies has been collected at Blue Mounds on Vvularia grandiflora. 

 It is not unlikely that North Am. Fungi 2153 issued under 

 the nomen nudum Phyllosticta uvulariae Galloway is of this 

 character. (See 4th suppl. list under No. 359.) Microscop- 

 ically this fungus suggests Phyllosticta cruenta (Fr.) Kx. Oc- 

 casional biseptate sporules occur as is to be expected. 



Stagonospora intermixta (Cke.) Sacc. Price Co., Oct. 9, 

 1911. On leaves of Cinna arundinacea. I have not seen an
