Specialized asexual reproduction by cylindric to fusiform gemmae, longitudinal walls absent. Sexual condition dioicous. Sporophytes unknown.

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.
