Abstract

Uromycladium falcatarium sp. nov., the cause of gall rust on Paraserianthes falcataria in south-east Asia.

Abstract

The gall rusts on Acacia spp. and Paraserianthes falcataria are caused by species of Uromycladium. Morphology and a phylogenetic analysis of four loci from ribosomal (SSU, ITS, LSU) and mitochondrial (CO3) DNA, showed that the rust on P. falcataria differed from U. tepperianum. Uromycladium falcatarium sp. nov. is described to accommodate this taxon, which can be differentiated from other species of Uromycladium by teliospore wall morphology, host genus and DNA sequence data.
