Likin’ the Lichen

lichen

Lichens are made up of two types of life forms: a symbiotic organism (fungus) plus a photosynthetic partner (green alga or cyanobacterium). The fungus part gets its nutrients from the air and rain, the photosynthetic one makes its own food with the sun’s help. Lichens have been used in making dyes and perfumes, as well as traditional medicines.

In the presence of environmental toxins, lichens perish, but when the air is clean, they thrive. So, their prevalence in the area was very good news. I took deep breaths and snapped my photos.

    Isn’t that how Dr. Albert Hoffman discovered LSD?

      Does the L in LSD stand for lichen, then?
