1. Phlegmariurus Holub, Preslia. 36: 17, 21. 1964.

Hanging fir-moss [based on epithet of Lycopodium phlegmaria ; Greek phlegma, flame, and oura, tail; in reference to the tasslelike fertile portions of the plant]

Plants epiphytic or terrestrial, pendent [erect]. Roots produced in distal parts of shoots, migrating downward in cortex to emerge in substrate. Horizontal stems absent [present]. Shoots clustered, round in cross section, dichotomously branching, 1.5--5 mm diam. Leaves not in distinct ranks [ranked], imbricate or not, monomorphic (or sporophylls sometimes differentiated), appressed, ascending to spreading, linear to subulate, margins mostly entire [denticulate]. Gemmiferous branchlets and gemmae absent. Sporangia reniform, borne individually in axils of undifferentiated or slightly differentiated sporophylls [differentiated sporophylls in strobili]. Spores pitted to small-grooved, sides at equator convex and angles acute. Gametophytes nonphotosynthetic, mycorrhizal, mainly growing buried in humus on trees, branched, paraphysate with uniseriate hairs; ring meristem absent. x = 68.

Species over 300 (1 in the flora): in tropical areas worldwide.

As construed here, Phlegmariurus is very large and diverse. Many groups have been tentatively suggested in this genus (B. ├śllgaard 1987). Some of these ultimately may be recognized as subgenera or even genera.
