Capsule inclined, curved; neck 2–3 times as long as urn when dry, long-cylindric, strumose at base; peristome teeth 2-fid or irregularly perforate, not fragile, commonly persistent; annulus compound, revoluble.

Discussion
Trematodon longicollis is much like T. ambiguus but differs in the relative lengths of capsule urn and neck when dry, and is clearly more southern in distribution. The peristome may occasionally adhere to the operculum on dehiscence and the capsule may then falsely appear gymnostomous.
