Porella platyphylla (Linnaeus) Pfeiff.

Family: Porellaceae

Status: Native

Synonyms:
None

Porella platyphylla is a relatively large liverwort that grows into large mats on rock substrates. The leaves are ovate and entire with a large and entire dorsal lobe. There are also large underleaves, giving the impression from the undersurface that there are five large leaf-like structures across the stem (2 dorsal lobes, 2 ventral lobes, and the underleaf.) The oil bodies are minute and hardly visible even at 400x. Please click on an image for a larger file.
