Family: Bryaceae
Status: Native
Synonyms:

Brachymenium exile (Dozy & Molk.) Bosch & Sande Lac.
Osculatia exilis (Dozy & Molk.) Ochyra, Plášek & Bedn.-Ochyra
Gemmabryum exile is unusual among the genus Gemmabryum in its long, stringy habit,
and the obvious presence of abundant axillary bulbils and rhizoidal tubers. The tubers are typically
from 100-200µm in size. These characters together make
it fairly easy to recognize. The leaves have plain margins, no distinctive border, and a costa that
is excurrent into an orange awn in this specimen (but is apparently shorter in other specimens).
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp & Dina Clark for allowing us
to photograph this specimen.
