Guide to Liverworts of Oregon: Nardia breidleri (Limpr.) Lindb.
HOME SPECIES INDEX GENUS INDEX GLOSSARY
Nardia 1 one oil body per cell > Nardia breidleri
Synonym: None.
Special Status: None.
Recognition: Living material is characterized by the clear, colorless, solitary oil bodies. Sterile material can be tricky to name with confidence because the underleaves may not be easy to find. Underleaves are often eroded or poorly developed. The female shoot tips develop a thick pouch which cups the archegonia and young sporophytes called a marsupium. It does not enclose them completely as in Geocalyx and Calypogeia.
Distribution: On soil; in the Cascade Mountains. A stray shoot was recovered from a bottom sample from Waldo Lake.
Comments: This is one of the small, terrestrial liverworts that may form extensive mats in the subalpine or alpine zones, along with Anthelia. It is probably more overlooked than rare.
