| Lycopodiaceae | Dendrolycopodium | Groundpine, Tree-clubmoss |  (c) Fleming, Gary P. | ||
| Lycopodiaceae | Dendrolycopodium dendroideum | Tree Groundpine, Round-branch Clubmoss, Prickly Tree-clubmoss | Openings, grassy balds, high elevation spruce-fir and northern hardwood forests. | The northernmost of the L. obscurum complex, ranging from n. Québec and Newfoundland and Labrador (Newfoundland) west to Alaska, south to s. New Jersey, w. North Carolina, Missouri, Minnesota, South Dakota, Colorado, Montana, Idaho, and Washington. Petrewski (2020) found that plants previously attributed to D. dendroideum in e. Asia are not part of this species. |  (c) Fleming, Gary P. |
| Lycopodiaceae | Dendrolycopodium hickeyi | Delicate Tree-clubmoss, Pennsylvania Groundpine, Hickey's Tree-clubmoss | Grassy balds, bog margins, forest openings, acidic ridgetop forests. | N. Québec and Newfoundland and Labrador (Newfoundland) west to Minnesota, south to New Jersey, sw. North Carolina, and n. Indiana. |  (c) Fowler, Jim |

| Lycopodiaceae | Diphasiastrum | Flat-branched Clubmoss, Running Cedar |  (c) Sorrie, Bruce A. - CC-BY | ||
| Lycopodiaceae | Diphasiastrum ×habereri | Dry forests. | Known from widely scattered localities in our area; not always in close proximity to its parents. | ||
| Lycopodiaceae | Diphasiastrum ×verecundum | Bashful Ground-Cedar | |||
| Lycopodiaceae | Diphasiastrum complanatum | Northern Running-Cedar | Forests, woodlands, edges. | The presence of this species as far south as s. New York and ne. Pennsylvania is complicated. Alleged by Gleason & Cronquist (1991) to reach "south in our range to Pa. and Minn.". Wherry et al. (1979) cited numerous occurrences in Pennsylvania which have since been annotated as D. ×habereri; however, Rhoads and Block (2007) later rejected this species from Pennsylvania, apparently due to a lack of specimens. It has been documented in Sullivan County, New York, which sits at the Pennsylvania/New York border; however, Werier et al. (2022) explain that many specimens collected in New York labeled as D. complanatum may actually be D. digitatum. Lastly, some specimens collected in northeastern Pennsylvania appear to potentially be D. complanatum (S. Grund, pers. comm.; 2022); however, these and the aforementioned specimens need critical examination before we can confirm or deny the legitimate (historical or current) presence of this species in Pennsylvania. | |

Tennessee (Blount County); Asian material is segregated as S. lioui Li Bing Zhang (Chen et al. 2021). This species was reported for North Carolina by Lellinger (1985) and FNA, and is apparently indicated as occurring in North Carolina on the range map in Mickel (1979); there is apparently no documentation for these reports, though the species occurs in Grayson County, Virginia, a county adjacent to North Carolina. In 2022, it was found in Haywood County, North Carolina. |  (c) Sorrie, Bruce A. - CC-BY |
