There are only two previous citations since the 20th Century of this smut species for Romania. However, this relates to herbarium material collected for the first time in 1957 in Târgu Mureș recorded by K. Vánky (according dataset: The Fungal Collection at the Botanische Staatssammlung München) and to the second collecting in 1978 in Valea lui Mihai-Șimian, Brașov by Negrean G. (according dataset: The Fungal Collection at the Senckenberg Museum für Naturkunde Görlitz). In the present paper the interaction between the phytopathogenic fungus Ustilago syntherismae and the plant at which it infects, Digitaria sanguinalis, has been studied. Aspects related to the phenotypic expression (symptoms) manifested by Digitaria sanguinalis under field conditions and to the morphological characteristics of the spores of the fungus Ustilago syntherismae are presented. The observations took place in the period 2018-2020.Further research is required to investigate the current distribution of the loose smut - Ustilago syntherismae (Schweinitz) Peck on Digitaria sanguinalis (L.) Scop.in Romania.
