and generally a little thicker toward one end. In size they are .0006 to 

 .0009 in. long, .0003 to .0004 broad. Fuckel considers the species as the 

 stylosporous condition of Trochila Salicis, Tul. It is very unlike Glce- 

 osporium salicinium, Pk., -which is rather a Septoglceum, though the 

 septa are obscure. 



Marsonia Quercus, n. sp. 



Spots angular or suborbicular, whitish or reddish-gray, definite, nucleus 

 hypophyllous ; spores oblong or subcylindrical, straight or curved, 

 slightly constricted in the middle, obscurely uniseptate, colorless, .0005 

 to .0006 in. long, .0001 to .00016 broad, oozing out and forming a red- 

 dish or reddish-amber colored tendril or mass.

Pestalozzia monochaetoidea, S. <& E. 



Dead stems of nine-bark, Spircea opulifolia. West Albany. Apr. 



Ramularia Diervillae, n. sp. 



Plate 1, figs. ] 6-18. 



Spots suborbicular, whitish or cinereous with a dark-brown margin, 

 definite ; flocci amphigenous, minute, tufted ; spores cylindrical, color- - 

 less, .0005 to .001 in. long, .00008 to .00016 broad. 



Living leaves of Diervilla trifida Adirondack mountains. June. 



Ramularia multiplex, n. sp. 



Spots large, sometimes occupying the whole leaf, red or greenish- 

 yellow, becoming brown when old, the lower surface, and sometimes 

 both surfaces, frosted by the fungus ; flocci and spores whitish or sub- 

 cinereous, the latter very variable, subglobose elliptical, oblong or cylin- 

 drical, .00016 to .002 in. long, .00016 to. 0002 broad, sometimes catenu- 

 late. 



Living leaves of cranberry, Vaccinium Oxycoccus. Caroga. July. 



Ramularia Prini, n. sp. 



Plate 1, figs. 19-21. 



Spots small, suborbicular, cinereous or whitish, with a brown margin, 

 definite: spores hypophyllous, oblong or subfusiform, colorless, .0005 

 to .0009 in. long, .00016 to .0002 broad. 



Living leaves of Ilex verticillata. Caroga. July. 



The spores are tufted, but so minute that they are scarcely visible to 

 the naked eye. This and the two preceding species are referred to the 

 genus Ramularia with some hesitation. The hyphae are minute and ob- 

 scure, and I have seen no septate spores, but in other respects they ap- 

 pear to belong here. The next species, which rarely has uniseptate 

 spores, forms a connecting link between these and the succeeding one. 



Ramularia Oxalidis, Farl.
