Phyllosticta Amaranthi, E. & K.— On leaves of A. retrofiexus. 

 Garden City, Ks., Aug. '84. On reddish brown (2— 4 mm.) spots with a 

 dark, slightly raised border. Perithecia &— 12 on a spot, epiphyllous, 

 erumpent, rather large ; spores oblong-elliptical, 2-nucleate, 9—11 x 3—5 /^-, 

 Differs from P. Chenopodii, West, in its larger perithecia and spores and 

 in the different character of the spots. 



Phyllosticta abortiva, E. & K. — On leaves of Menispermmi (Jan- 

 adense, Manhattan, Ks., Nov. '84. Spots brown, suborbicular, (i — 1 cm.) 

 with a definite darker colored but scarcely raised margin. Perithecia

NEW FUNGI FROM IOWA. 



BY J. B, ELU8 AND E, "W. HOLWAY. 



The species here described were collected by Mr. Hoi way in the vicin- 

 ity of Decorah, Iowa, mostly during the summer and fall of 1884. 



Hypocrea cubispora, E. & Hoi.— Stroma tuberculiform, obconic, 

 subplicate below, about 1 cm. broad and f cm. high, lemon-yellow within 

 and without, surface punctate with the black ostiola ; perithecia peri- 

 pheric, glob )se ; asci cylindrical containing 8 sub ubical, dark olive or 

 brownish black, 2-nucleate, 4—6 x 3—4 /^-, sporidia, some of which are 

 obscurely uniseptate. On an old log, August. 



DiATRYPELLA PopULi, E. & Hol.— Pcrlthecia cartilaginous, ovate 

 or subangular by mutual compression (i- 1 mm.) closely packed in an 

 orbicular lens-shaped stroma, 2—3 mm. in diam., dark brown outside 

 dirty white within and seated on the surface of the inner bark ; ostiola 

 short, stout, tips obscurely 4-cleft and united in an obscure black disk or 

 piercing the epidermis separately; asci long clavate, 100 — 115 x 15 p-; 

 sporidia cylindrical, yellowish, curved, 10—12 x H— 2 /^-. The surface of 

 the wood is blackened except directly under the stroma where it retains 

 its light color. On dead limbs of Populus, Aug. 1883. 



Valsa Mentspermi, E. & HoL— Perithecia circinating in a cortical 

 stroma without any circumscribing line, 6—10 in number and about i mm. 

 in diam., with membranaceous, coarsely cellular walls ; ostiola very 

 short, united and concealed in a circular disk i—} mm. in diam. and 

 entirely covered by the epidermis through which its outline is seen as a 

 small black circle with a black dot in the center ; asci clavate, 70 x 12 ; 

 sporidia crowded, cylindrical, yellowish, curved, 15—20 x 4—6 On 

 stripping oft" the epidermis the perithecia sometimes adhere to it and
