194 Artuur: NEW SPECIES OF UREDINEAE—XIV 
Cronartium filamentosum (Peck) Hedge. (Peridermium fila- 
mentosum Peck, 1882); 
Cronartium coleosporioides (Diet. & Holw.) Arth. (Uredo 
coleosporioides Diet. & Holw. 1893); 
ronartium stalactiforme Arth. & Kern (Peridermium stalactt- 
forme Arth. & Kern, 1906). 
Should it be deemed advisable to combine these three species 
as subspecie’s, races, or forms, the name to be employed for the 
aggregate species, using the oldest specific name, would be

Diabole cubensis comb. nov. 
Uromycladium (?) cubense Arth. Mem. Torrey Club 17: 119. 
18. 
The species occurs in Cuba on Mimosa pigra L. (M. asperata 
L. ) and was at first assigned with many misgivings to the genus 
Uromycladium. That connection has become more and more 
uncertain, and it is now believed to constitute a new and very 
distinctive genus. 
Puccinia Plucheae (Sydow) comb. nov. 
Uredo Plucheae Sydow, Ann. Myc. 1: 1903 
Uredo biocellata Arth. Bull. Torrey Club 33: ayy. 1906. 
Puccinia biocellata Vestergr. Micr. Rar. Sel. 1267. 1908. 
The teliospores of this rust have been collected on two hosts, 
Pluchea fastigiata Griseb. and P. Quitoc DC., in Argentina, 
and issued in Vestergren’s exsiccati, Nos. 1267 and 1368. The 
rust occurs on a number of species of Pluchea in Florida, Guat- 
emala and the West Indes, but no teliospores have yet been 
found in North America. 
Uredo nominata sp. nov.
