NOTES: The species was first described by Durieu (1866) Eleocharis parvula. However, it has been infrequently collected and little studied and its position in the Ustilaginales questioned because of the hosts marine habitat which is “an anomalous ustilaginomycotinous habitat” (Va´nky1994). Bauer et al. (2007) in a study of the ultrastructure of teliospore walls, teliospore germination, hyphal septation, cellular interactions, and nucleotide sequences from the D1/D2 region of the nuLSU rRNA gene of Ustilago marina showed it differed from other Ustilaginaceae phylogenetically and in the mode of sporulation (occurs exclusively at the base of the host plant culms). They, therefore introduced the new genus Parvulago to accommodate U. marina.
