Plants to 0.7 cm. Stem leaves loosely erect and not contorted when dry, spreading to ± recurved when moist, oblong-lanceolate, 1–1.7 mm; margins entire; apex broadly acute, apiculus abrupt; costa ending near apex, abaxial surface covered by cells distally; basal laminal cells subquadrate to short-rectangular; distal cells 9–14 µm, papillae 2–4 per cell, walls somewhat thick. Specialized asexual reproduction by cylindric to fusiform gemmae, longitudinal walls absent. Sexual condition dioicous. Sporophytes unknown.


Habitat: Tree trunks, dead branches
Elevation: low elevations

Discussion

Zygodon conoideus is distinguished from Z. viridissimus by its wider, oblong-lanceolate leaves, larger laminal cells, and gemmae that have 4–7 horizontal, but no longitudinal, septa. The apiculus usually has a long, clear terminal cell.
