Doweld (2014) erected Cylindrochytriaceae to accommodate Cylindrochytridium Karling. Cylindrochytriaceae is characterized by a monocentric, eucarpic thallus with stalked, cylindrical, apically operculate zoosporangia; posteriorly uniflagellate zoospores with a single lipid globule; and branched, extensive rhizoidal systems with numerous catenulate spindle-shaped swellings. Rhizoids arise from a single (basal) place on a cylindrical and stalked sporangium (Steiger et al. 2012).
Type genus: Cylindrochytridium Karling
Other accepted species: Species Fungorum – search Cylindrochytriaceae
