and slightly unequal, few or many-nucleate, sometimes obscurely 

 uniseptate, colorless or slightly colored, .001 to .0016 in. long, 

 .00025 to .0003 broad. 



Living leaves of Perajphyllum ramosissimum. Southern Utah. 

 June. M. E. Jones. 



This is an aberrant species with the spores unusually broad and 

 variable and the perithecia rather large and somewhat unequal. 



Septosporium Equiseti n. sp. 



Hyphae forming minute tufts, the fertile very short, bearing 

 acrogenous spores, the sterile longer, septate, colored ; spores 

 elliptical, usually with three transverse septa and one or two 

 longitudinal ones, colored, .001 in. long, .0005 broad. 



Dead tips of branches of Equisetum arvense. West Virginia. 

 June. C. F. Millspaugh. 



Uromyces deciduus n. sp. 



Spots none ; sori minute, rotund, pulverulent, hypophyllous or 

 amphigenous, often surrounding the young branches and occupy- 

 ing the whole lower surface of the leaflets, less abundant on the 

 upper surface, rusty-brown ; teleutospores oblong-iUiptical or 

 oblong-pyriform, .0008 to .0012 in. long, .0005 to .0006 broad, 

 with the epispore roughened or verruculose, quickly deciduous 

 from the short pedicel, a few abruptly clavate or capitate para- 

 physes intermingled with the teleutospores,. 0012 to .0016 in. long. 



Living leaflets and young branches of the screw bean, Prosojns 

 jpubescens. Mescal mountains, Arizona. May. Jones. 



This species is easily known by its quickly deciduous spores and 

 the intermingled capitate paraphyses. The pedicels are from one- 

 fourth to one-half the length of the spores. " The fungus does 

 not kill the leaves but causes the stem to form fascicles or bird's- 

 nest clusters of branchlets near the end of the present year's 

 growth."
