724. Septoria galeopsidis West. 
On Galeopsis Tetrahit L. State Line. Sporules 
35—65 X 1% microns. 
'725. Septoria gratiolae Sacc. & Speg. 
On Gratiola Virginiana L. Radisson. This corre¬ 
sponds with the description of S. gratiolae E. & 
M. which I assume is not distinct. This seems 
hardly distinct from the fungus on Veronica ar- 
vertsis L. referred to Septoria veronicae Desm. in 
the supplementary list (No. 458) although there 
is a slight difference in the size of the pycnidia 
which are 65 microns in diameter on Gratiola 
and 70—75 on Veronica. 
'726. Septoria hyalina E. & E. 
On Viola blanda Willd. Genoa Junction, Dousman, 
Sullivan and Vilas county. 
On Viola pubescens Ait. Racine. 
727. Septoria lactucicola E. & M. 
On Laduca Canadensis L. Raymond and Berryville, 
'728. Septoria lycopersici Speg. 
On Lycopersicum esculentum Mill, (cult.) Racine. 
Some tomato growers consider the presence of 
this fungus desirable because it hastens the ripen¬ 
ing of the fruit. 
'729. Septoria lythrina Pk. 
On Lythrum alatum Pursh. Union Grove. In this 
collection the pycnidia are hypophyllous and the 
sporules continuous but sometimes plurinucleate. 
'730. Septoria nabali B. & C. 
On Prenanthes alba L. Racine. 
731. Septoria parietariae n. sp. 
Spots suborbicular to irregular, immarginate, fulig¬ 
inous ; pycnidia epiphyllous but showing through 
beneath, scattered, dark brown or black, globose, 
opening by a round pore, 70—100 microns in 
diameter; sporules hyaline, bacillar^, straight or 
slightly curved, 30—36 X 1—1% microns.
