The endoplasmic reticulum of Saprolegnia, Dictyuchus, Synura and Cryptomonas may contain tubules less than 20 nm in diameter. In Saprolegnia these tubules have a maximum length of 1.6 µm, a wall of a single layer of colchicine-resistant, osmiophilic subunits, and a tapering end-piece. Flimmer hairs (flagellar hairs) are morphologically similar and are attached to the flagellum sheath by a tapering end-piece. It is suggested that Flimmer hairs are produced in cisternae of the endoplasmic reticulum of the above organisms. Cryptomonas bears 2 rows of Flimmer hairs on one flagellum and a single row of shorter ones on the other.
