Observation 11633: Lichen P. Micheli
When: 2008-09-27
No herbarium specimen

Notes: This may be more of the same observation I just posted, or it could be something different, my lack of lichen lore being what it is. Photos taken of lichen growing from a decorative chunk of lava which I use as a decorative plant planter. These extensions have a more fluted appearance in their post horn shape than the first observation, so am submitting as a separate observation. But taken on the same rock (which I realize doesn’t mean much).

Sorry, I don’t think we can get to species on this

without more detail. Need macros of the cups to see the texture of the soredia (if present). Shape and color of squamules and cups (inside and outside cups) can also be helpful. Also would be useful to know if they have fumarprotocetraric acid (K~ brownish C- KC- PPD+ orange/red) or usnic acid (K- C- KC+ golden PPD-), but note that this is correlated with presence of red pycnidia or apothecia in western species: check color of dots along the rim of the cups very carefully.
