Trichodon W. P. Schimper, 1856.

Trichodon is a genus segregated from the acrocarpous and subulate leaved Ditrichum. The basis for this segregation lies in the strongly expanded leaf base that allows for the clasping base to be distinguished from the squarrose leaf limb. The subula of Trichodon is more papillose-prorate than most species of Ditrichum. Like most species of Ditrichum, Trichodon has plane to basally incurved leaf margins. It is found on muddy road or trail banks primarily in the northwestern portions of California. Sporophytes have not been seen on Trichodon in California, and this may account for the scarcity of its collection.
