twigs. In some unsprayed orchards, every fruit on certain trees 

 was cracked open on account of it. 



Septoria erigerontis B. & C. Monroe County. 1923. 3969. One of 

 our most common parasites. These have pycnidia 100 to 12.5 microns 

 in diameter; spores, 1.5 to 2 by 30 to 70. These spores evidently 

 never have been carefully measured. S. erigerontis B. & C. is said 

 to have spores 38 microns long and those of S". eHgerontea Pk. are 

 given as 25. 



Septoria piricola Desm. On leaves of Pyrns communis, Clark County, 

 October 1, 1922. Trees practically defoliated. 3939. 



Sjihaeropsis iiudor^iDi Pk. On apple leaves and fruit October, 1920. 

 Common. 3803. 



Vermicularia Deviatium (Pers.) Fr. On dead spots in leaves of Frax- 

 inus americcma, August 1, 1923. Monroe County. 3971. 



Vermicularia Liliacearum Westend. On living leaves of Fuukia ovata, 

 July 16, 1920. 3789. On Convallaria majalis, July IG, 1920. Kay. 

 Both collected in Monroe County. Spots oval or elongated, spread- 

 ing indefinitely, border brown, center light; pycnidia globose, oval, 

 or varying in shape and size up to 125 microns in diameter; setae 

 on or around the pycnidia, dark brown, 50 to 100 by 5 to 6, lighter 

 at tips, septate, sometimes bent or enlarged variously at base; 

 spores fusiform, mostly acute, some obtuse, for the most part, 

 curved, usually two guttulate, hyaline, 3 to 4 by 12 to 25 microns. 



Melanconiales. 



Gloeosporium nervisequum (Fckl.) Sacc. (See Gnomonia veneta.) 

 Hyphomycetes. 



Cercospora ampelopsidis Pk. On living leaves of Avipelopsis quiyique- 

 folia, Lawrence County, July 16, 1922. 3925. 



Cercospora canescens E. & M. On living leaves of Lima bean, Clark 

 County, October 1, 1922. 3931. On common bean, Phaseolns vul- 

 garis, Monroe County, July 30, 1923. 3973. Since our specimens 

 vary somewhat from the original description, a redescription is 

 added for Lima bean. Spots on dried leaf, fading out and becoming 

 paler in center, circular or irregular, 1 to 10 mm. in diameter, very 

 numerous, sometimes showing concentric rings, often coalescing and 

 covering large areas finally killing the leaves ; below, the spots about 

 as evident, but not becoming so pale in the center. Conidiophores 

 amphigenous, brown, straight or curved, sometimes nodulose, 50 

 to 275 microns long, slightly tapering above and some paler at 

 tip. Spores straight or curved, hyaline, 5 to 20 or more septate, 

 3 to 5 by 100 to 225. 



Cercospora cercidicola Ell. On living leaves of Cercis canadensis, Mon- 

 roe County, June 22, 1923. 3972. This specimen varies from the 

 description as follows: Conidiophores 100 to 150 by 4 to 5, bearing 

 several spores, fasciculate character noticeable, the lower half fre- 

 quently forming a column; spores yellowish, 18 to 55 by 4 to 6, one 

 to three septate, when typically developed about 50 by 5 and two 

 septate.
