[2] The type species is Dictyosporium elegans, which was described by August Carl Joseph Corda in Witenweber (1836).

[7] The family of this genus, Dictyosporiaceae, was created to accommodate a holomorphic group of Dothideomycetes, including 12 genera that are saprobes on decaying wood and plant debris in terrestrial and freshwater habitats.

[7] The genus was analysed molecularly and was previously situated phylogenetically inside the Massariinaceae family.

But in 2015 Tanka et al. changed its position and situated the genus inside the current family Dictyosporiaceae.

In 2015 D. araucariae, D. indicum, D. hydei, D. olivacesporum, D. pseudomusae, D. sexualis, D. splendidum and D. wuyiense were newly identified.
