Ecology & Life History

Basic Description: An evergreen clubmoss with short, upright branches, scale like leaves, and axillary spore cases.
Technical Description: Erect shoots from a short base, generally unbranched, .5-1.7 dm high and 10 mm in diameter, undulate in outline due to the differences in sporophyll size. Plants green in color, becoming yellowish at the base of older plants. Leaves to 8 mm long, parallel sided (linear-lanceolate) few if any teeth. Stomates on the upper surfaces of the leaf only. Lateral lobes of gemmae narrow with acute tip.
Diagnostic Characteristics: Spores not in strobili, but borne on stem, leaves broadest at the base, widely spreading nearly entire, erect shoots rarely branched.
Duration: PERENNIAL, EVERGREEN
Reproduction Comments: Forms sterile hybrids with L. lucidulum. Gemmae provide asexual replication; n=64.
Ecology Comments: Grows in association with mosses and often L. lucidulum on cool, damp, shaded ledges.
Terrestrial Habitat(s): Forest - Conifer, Forest - Mixed, Forest/Woodland
Habitat Comments: Moss covered cliffs and ledges of acidic sandstone in shaded situations. (Has been recorded from limestone (soil pH 6.3) A32WIL01PAUS.
