316 SHEAR: NEW SPECIES OF FUNGI 
ascogenous form has been obtained. It agrees in general char- 
acters with the conidial form of Glomerella rufomaculans Vaccinn 
Shear, but the conidia are constantly smaller, being only half as 
long, and we have been unable to find any indication of intergra- 
dation in this respect. 
Guignardia Vaccinii sp. nov. 
Pycnidia. Pycnidia, rather thickly and evenly distributed over 
the surface of affected leaves, usually hypophyllous, 100-120 # 
diameter, globose or depressed-globose, buried at first, finally 
somewhat erumpent, with the apex and short or nearly obsolete 
-ostiolum breaking through the epidermis; pycnospores 10.5-13.5 
x 5-6, smooth, hyaline, or amber-colored when fully mature 
and in mass, obovate and usually somewhat flattened at the apex, 
bearing a somewhat inconspicuous, granulate-mucilaginous curved 
appendage averaging about three fourths the length of the spore; 
sporophores 10-15 p long. 
Perithecia, Perithecia practically identical in size, shape, text- 
ure and mode of growth, with the pycnidia; asci 8-spored, clavate- 
cylindric, usually short-stipitate, non-paraphysate, 60-80 x 9-12}; 
spores smooth, hyaline, or when fully mature pale greenish-yellow, 
ie pias or subrhomboid and somewhat inequilateral, 13.5-16.5 
5-7 B. 
Type, zo. 1476 C.L.S., on leaves of Vaccinium macrocarpum, 
near Lakewood, New Jersey, September 4, 1904. We also have 
specimens from Morgantown, West Virginia; Wareham, Massa- 
chusetts ; Arichat, Nova Scotia ; and Grand Rapids, Wisconsin. 
This fungus was described and figured without a name by Dr. 
B. D. Halsted in Bull. N. J. Agr. Exp. Sta. 64: 33-35. 1889. 
The figure of ascospores given by Dr. Halsted does not corre- 
spond exactly with our specimens, but the plant represented is 
probably the same. The plant has also been described and fig- 
ured by the writer, but Nini specific name, in U. S. Dep. Agric. 
Farm. Bull. eek Soe oe T4 1905. 
This species is tan related to Guignardia Bidwell (Ell.) 
Viala & Rav. 
It causes a serious disease of the cultivated cranberry, gen- ¢ 
erally called “scald” by growers. Itattacks the berries when they 
are very small, causing them to shrivel up, turn black and become 
covered with pycnidia; when half-grown or more the fruit be- 
comes very soft and watery. The connection between the pycni-
