[ Rhabdostyla] (Rhabdostyla) muscorum Kahl, 1935: 675 , pl. 138, fig. 9, 9a and 9b

Epistylis (Rhabdostyla) muscorum Kahl, 1935 — Stiller, 1971: 70, pl. 36, fig. I

Diagnosis: Size about 40µm. Elongated vase-like body, with two grooves in the basal part. Thin peduncle, measuring approximately 20 µm to about a third of the body size. Peristomial collar thick. Peristomial disc is flat and low. Infundibulum reaching halfway through the body. Contractile vacuole found on the right side of the infundibulum in the upper third of the body. Macronucleus elongated and positioned longitudinally, has a fold at the top. Found in moss infusions.

Remarks: diagnosis compiled from Kahl (1935) and Stiller (1971). According to Kahl (1935), it has a very characteristic contractile form and the furrows in the most basal part of the individuals have been little studied and need more attention.
