Seta superficial cells usually lightly papillose near the base, cells spirally twisted but interspersed with sections of straight, prorulate cells.

Capsules mature spring--early summer. Rare, on well-decayed wood, stumps, and logs, B.C., N.B., Nfld. and Labr. (Labr.), N.W.T., Colo., Mont., Wyo., Russia.

Tetraphis pellucida var. trachypoda has been synonymized under both T. geniculata and T. pellucida. It proved, in fact, to be an intermediate form between T. geniculata and T. pellucida. Tetraphis pellucida var. trachypoda occurs in North America and Russia, although at the present time the geographic range in Russia is little known. Based on the North American material examined it appears to only be found in areas where both T. pellucida and T. geniculata occur, suggesting that it might be found in the Russian Far East where both of these species also overlap.
