Type speciesDictyocyclus hydrangeae Sivan., W.H. Hsieh & Chi Y. Chen, Bot. J. Linn.Soc. 126(4): 324 (1998).

Notes – Sivanesan et al. (1998) introduced this monotypic genus in Parmulariaceae. However, Dictyocyclus has similar characteristics to Myriangium, including single ascus inside each locule and muriform ascospores. Therefore, Dissanayake et al. (2014) based on morphology alone placed this genus in Myriangiaceae. Fresh collections and sequence data are needed to establish its familial position in Dothideomycetes. This is an epifoliar genus, characterized by muriform ascospores with 3–5 transverse septa, and one longitudinal or oblique septum in each of the end cells (Dissanayake et al. 2014).
