Key Identification Features
- Scytinium lichenoides is a jelly lichen that produces often distinctly fringed lobes.
- The lower surface usually has prominent, often vertically oriented ribs, and may develop a slight cobwebby texture near the base.
- In cross-section, the thallus has a distinct cortex made of angular cells, which sits above a medulla of intertwined fungal hyphae.
- It lacks distinct layers, as well as an upper or lower cortex, and its cyanobacterial partner is spread evenly through the entire thallus.
