Discussion
Taxiphyllum deplanatum is widespread in northeastern North America with disjunct populations in New Brunswick, Quebec, Saskatchewan, Arizona, and New Mexico. Taxiphyllum deplanatum has often been confused with T. taxirameum, but the two are easily distinguished superficially and microscopically. The flaccid, appressed-imbricate leaves characteristic of T. deplanatum will easily separate it from T. taxirameum with its rigid, usually distant, wide-spreading to squarrose leaves. The alar regions of T. deplanatum are well differentiated with quadrate to short-rectangular cells, 3–8 in the marginal rows, which is in striking contrast to the poorly differentiated alar regions of T. taxirameum that have only a few rectangular cells on the margins. Taxiphyllum deplanatum has been reported for the Gulf Coast region, based on a Louisiana specimen (R. R. Ireland 1969b). However, it was re-examined and found to be a misidentified specimen of T. taxirameum as W. D. Reese (1984) noted. The capsules are extremely rare.
