Guide to Liverworts of Oregon: Ptilidium ciliare (L.) Hampe
HOME SPECIES INDEX GENUS INDEX GLOSSARY
1b plants leafy > 3a leaves divided 1/2 or more > 4a lobe base laminar > Ptilidium 1 lobe tips not attenuate > Ptilidium 2b biggest lobe more than 14 cells wide > Ptilidium pulcherrimum
Synonym: None.
Special Status: None.
Recognition: The general appearance of this species is much more soft and fuzzy than our common species in the genus, P. californicum because the cilia are strictly uniseriate from a flat lobe. This soft appearance is shared with P. pulcherrimum, from which it differs in having wider lobes.
Distribution: Usually grows on bark or wood; not yet found in Oregon, it is found in Washington, on the Olympic Peninsula, and may turn up in NW Oregon.
Comments: To be searched for in our highest elevation, moist forests.
