HABITAT hardwood forest on top of small hill in bottom of steep valley; SUBSTRATE siliceous rock and thin mineral soil over rock, frequently growing over other nearby lichens; ASPECT partly sunny; NOTES thallus subcoralloid with nearly terete branching minute lobes, nearly entirely sterile but for one apothecium with incomplete thalline margin, K-; SPORES 8 per ascus, oblong to slightly bent, ~15 × 5 µm.

This is the typical form in chaparral of the San Gabriel Mountains, it seems. I’m not sure why, but it is very rarely fertile, and nearly coralloid. But happily I was actually able to locate an apothecium for the first time ever in material from this area.


Large sterile squamulose colony.
Subcoralloid form.
